How to Analyze an AR Aging Report and Prioritize Claims

An AR aging report can contain hundreds or even thousands of unpaid medical claims.

If you simply start at the top of the report and work downward, you may spend an entire day on low-value or low-risk accounts while more urgent claims approach:

• Timely filing deadlines
• Appeal deadlines
• Authorization expiration issues
• Old AR status
• High financial exposure
• Final payer limits

That is why experienced AR representatives do not treat every outstanding claim equally.

They prioritize.

The purpose of an AR aging report is not only to show:

How much money is outstanding?

It should also help answer:

Which claims require attention first?

Why are they unpaid?

Which balances are most at risk?

Which payers are creating delays?

Which claims have the greatest recovery opportunity?

A strong AR representative learns to combine:

Age + Balance + Denial Reason + Deadline + Payer + Claim Status + Recoverability

to decide what should be worked first.

This guide explains how.

What Is an AR Aging Report?

An Accounts Receivable aging report shows outstanding balances grouped according to how long they have remained unpaid.

Common aging buckets include:

• 0–30 days
• 31–60 days
• 61–90 days
• 91–120 days
• 120+ days

Some organizations use different ranges, such as:

• 0–30
• 31–60
• 61–90
• 91–120
• 121–150
• 151–180
• 180+

The exact structure depends on the billing system and organization.

The basic purpose is the same:

Identify how old outstanding receivables are.

What Information Can an AR Aging Report Contain?

Depending on the billing system, the report may include:

• Patient name
• Account number
• Date of service
• Payer
• Provider
• CPT/HCPCS
• Billed amount
• Outstanding amount
• Aging bucket
• Claim status
• Last payment
• Last follow-up
• Denial information
• Patient responsibility
• Insurance balance
• Claim number
• Location
• Specialty

A good AR representative does not look only at the age column.

The other fields help determine why the claim remains unpaid and how urgently it needs attention.

Why AR Prioritization Matters

Imagine you have these three claims:

Claim A

Age: 32 days
Balance: $12,000
Status: Denied for authorization
Appeal deadline: 8 days remaining

Claim B

Age: 125 days
Balance: $45
Status: Payer processing

Claim C

Age: 68 days
Balance: $2,500
Status: Claim not on file
Timely filing deadline: 5 days remaining

Which should you work first?

If you follow age alone:

Claim B is oldest.

But based on financial and filing risk:

Claim C and Claim A are much more urgent.

This demonstrates a core AR principle:

Oldest does not always mean highest priority.

The Main Factors Used to Prioritize AR

A strong prioritization strategy typically considers:

1. Filing and appeal deadlines
2. Claim balance
3. Claim age
4. Denial reason
5. Claim status
6. Payer
7. Recoverability
8. Last follow-up
9. Documentation availability
10. Root cause
11. Financial impact
12. Patient responsibility status

These factors should be considered together.

Priority 1: Claims With Filing or Appeal Deadlines

Deadline-sensitive claims should receive immediate attention.

Examples include:

• Timely filing deadline approaching
• Appeal deadline approaching
• Corrected claim filing deadline
• Reconsideration deadline
• Documentation submission deadline

A $500 claim with three days left before an appeal deadline may be more urgent than a $5,000 claim that still has several months available.

Once a deadline expires, recovery may become much more difficult.

Timely Filing Risk

Before resubmitting or correcting an old claim, ask:

• What is the payer's filing limit?
• When was the original claim submitted?
• Did the clearinghouse accept it?
• Did the payer receive it?
• Is there a payer claim number?
• Do we have proof of timely filing?

An unresolved clearinghouse rejection can be especially dangerous because the payer may never have received the claim.

For more information, read:

Timely Filing in Medical Billing: Limits, Denials & Proof of Timely Filing

Appeal Deadline Risk

Denied claims can have separate appeal or reconsideration deadlines.

When working denied AR:

Do not only ask:

How old is the claim?

Also ask:

How much time remains to challenge the denial?

An appeal deadline may expire before the claim reaches the oldest aging bucket.

That is why denial work queues should include deadline tracking whenever possible.

Priority 2: High-Dollar Claims

High-balance claims deserve close attention because one unresolved claim can represent more revenue than dozens of smaller accounts.

For example:

Claim A

$15,000 outstanding.

Claims B–Z

25 claims at $100 each.

The high-dollar claim may justify earlier investigation because of its financial impact.

However:

High balance alone should not override filing deadlines or recoverability.

A $20,000 claim with no realistic recovery path should not consume unlimited staff time while recoverable accounts expire.

How to Identify High-Dollar AR

Organizations may define high-dollar claims differently.

Examples might include:

• Top 10 balances
• Claims over a fixed threshold
• Top 5% of open AR
• High-value procedure claims

The exact threshold should depend on:

• Specialty
• Average claim value
• Payer mix
• Provider type

A surgery practice and a behavioral health practice should not necessarily use the same dollar threshold.

Priority 3: Claims Near 90 or 120 Days

Claims moving into older buckets deserve increasing attention.

Why?

Because as claims age:

• Payer history becomes more complex
• Appeal windows may narrow
• Documentation can become harder to obtain
• Coverage may change
• Staff may lose track of previous actions
• Recoverability may decline

Claims approaching:

90 days

or:

120 days

should often receive more structured review.

Why 120+ AR Is Important

120+ AR can represent:

• Complex denials
• Repeated follow-up failures
• Enrollment problems
• Timely filing issues
• Appeals
• Underpayments
• COB problems
• Unworked claims

A high 120+ balance can indicate that the organization is resolving new claims but failing to close difficult old accounts.

This makes 120+ AR an important management and AR metric.

Priority 4: Claims With No Payer Record

A claim may appear in AR even though the payer never received it.

Common causes include:

• Clearinghouse rejection
• Wrong payer ID
• Claim not transmitted
• Claim routed incorrectly
• Invalid provider information

These claims should be reviewed quickly because timely filing may still be running.

A useful workflow is:

Check billing system
↓
Check clearinghouse
↓
Check payer acknowledgment
↓
Confirm claim number

If no payer record exists, determine whether the claim needs correction and resubmission.

Priority 5: Denied Claims With Actionable Causes

Some denials can be resolved relatively quickly.

Examples may include:

• Missing authorization information
• Incorrect modifier
• Wrong member ID
• COB update
• Duplicate processing error
• Missing documentation
• Payer processing mistake

If the root cause is clear and the required action is available, these claims may be strong recovery opportunities.

The goal is to identify:

Actionable denials

rather than repeatedly reviewing accounts without a clear next step.

Denial Categories to Separate

It can be useful to group denials into categories such as:

• Eligibility
• Authorization
• Timely filing
• Medical necessity
• Coding
• Duplicate
• COB
• Provider enrollment
• Non-covered service
• Missing information
• Underpayment

This makes it easier to identify recurring problems.

Top Medical Billing Denials: Common Causes, Codes & How to Resolve Them

Priority 6: High-Recovery Claims

Recoverability matters.

Consider:

Claim A

$8,000 denial.

No documentation exists, filing limits expired, and payer has issued final determination.

Claim B

$3,000 denial.

Valid authorization is available and payer allows reconsideration.

Claim B may deserve higher priority because it has a much stronger recovery path.

AR teams should avoid spending excessive time on balances that have little or no realistic recovery potential.

What Does Recoverability Mean?

Recoverability is the likelihood that the outstanding balance can still be collected appropriately.

Factors may include:

• Filing deadline
• Appeal rights
• Documentation
• Authorization
• Eligibility
• Provider enrollment
• Payer responsibility
• Contract
• Claim history
• Previous determinations

This requires judgment.

Priority 7: Claims With Long Follow-Up Gaps

A claim may only be 60 days old but still deserve attention if nobody has touched it for 45 days.

Review:

• Last follow-up date
• Last payer response
• Expected processing time
• Next action date

This can reveal accounts that have fallen out of the normal workflow.

Follow-Up Interval Matters

Follow-up should not be too frequent or too slow.

For example:

If a payer states:

Reprocessing takes 30 days.

Calling again after two days may waste time.

But waiting 90 days may allow the account to age unnecessarily.

A strong AR representative records:

• Action date
• Expected turnaround time
• Next follow-up date

and works the account accordingly.

Priority 8: Payer-Specific Backlogs

Sometimes the problem is not individual claims.

It is one payer.

For example:

• Payer A has normal aging.
• Payer B suddenly has many 90+ claims.
• Payer C has rising authorization denials.

This suggests a payer-specific issue.

AR reports should therefore be analyzed by:

• Payer
• Plan
• Product
• Region when relevant

This can reveal systemic problems.

Payer-Level Questions to Ask

When one payer has unusually high AR, ask:

• Are claims being rejected?
• Is payer processing delayed?
• Is provider enrollment active?
• Has payer ID changed?
• Are authorizations missing?
• Is a contract issue affecting payments?
• Are appeals pending?
• Is payment posting delayed?

A payer trend can be more important than an individual account.

Priority 9: Provider-Specific Problems

AR can also be analyzed by provider.

Suppose one physician has much higher old AR than others.

Possible causes:

• Enrollment issue
• Documentation delay
• Coding pattern
• Authorization issue
• Specialty-specific payer rule
• Incorrect provider configuration

Grouping AR by provider can help identify these trends.

Priority 10: Claims With Provider Enrollment Issues

Provider enrollment problems can affect many claims at once.

Examples include:

• Provider not enrolled
• Enrollment effective date issue
• Location not linked
• Taxonomy issue
• Rendering provider problem
• Reassignment issue

These should often be escalated quickly because one unresolved enrollment problem may affect dozens or hundreds of claims.

Why Enrollment Problems Can Be High Priority

Consider:

50 claims

all denied because provider enrollment is incomplete.

Working them individually will not solve the underlying issue.

The more effective action is:

Identify enrollment problem → Coordinate with credentialing/enrollment team → Resolve system issue → Reprocess affected claims

This is an example of root-cause management.

Priority 11: Claims With Authorization Issues

Authorization denials should be reviewed based on:

• Was authorization required?
• Was it obtained?
• Was it valid for DOS?
• Did CPT match?
• Did provider match?
• Did facility match?
• Were units available?

If valid authorization exists, there may be a strong recovery opportunity.

If none exists, review whether:

• Retro authorization
• Appeal
• Medical necessity review
• Another payer process

is available.

Read:

Prior Authorization in Medical Billing: Process, Requirements & Common Denials

Priority 12: COB Claims

Coordination of Benefits can keep claims outstanding for long periods.

Common situations include:

• Primary payer not updated
• Secondary payer waiting for primary EOB
• Patient has other insurance
• Payer order incorrect
• COB questionnaire incomplete

When working COB AR:

Verify:

• Primary insurance
• Secondary insurance
• Effective dates
• Primary EOB
• Payer order

COB claims can often be resolved once the correct payer hierarchy is established.

Priority 13: Underpayments

Do not focus only on completely unpaid claims.

A claim can be "paid" and still have an outstanding insurance balance.

For example:

Expected reimbursement: $1,000
Payer allowed: $850
Payment: $600

There may be:

• Incorrect adjustment
• Contract issue
• Coding reduction
• Modifier issue
• Underpayment

These claims should be identified separately from zero-payment denials.

Paid Does Not Always Mean Resolved

This is important.

If the claim shows:

Insurance payment posted

do not automatically assume:

AR resolved.

Review:

• Expected reimbursement
• Allowed amount
• Contract
• Patient responsibility
• Adjustments

Underpayments can remain hidden if incorrect write-offs are posted.

Priority 14: Patient Responsibility Errors

Some AR reports may contain balances incorrectly assigned to insurance or patient responsibility.

Before pursuing the payer, ask:

• Did payer assign deductible?
• Coinsurance?
• Copay?
• Was secondary insurance billed?
• Is QMB status involved?
• Is contractual adjustment correct?

The goal is to ensure the balance belongs to the correct responsible party.

Insurance AR vs Patient AR

These should usually be analyzed separately.

Insurance AR

Money expected from payers.

Patient AR

Legitimate patient responsibility.

Mixing them can distort:

• Aging
• Collection strategy
• Follow-up work

A claim may have both components.

Step-by-Step AR Aging Analysis

Now let's build a practical workflow.

Step 1: Review Total AR

Start with:

Total outstanding balance

This gives the overall size of the receivable.

But do not stop there.

A total AR number alone tells you very little about risk.

Step 2: Break AR Into Aging Buckets

Review:

• 0–30
• 31–60
• 61–90
• 91–120
• 120+

Calculate or review the percentage in each bucket.

Example:

Total:

$600,000

Now you can see where the risk sits.

Step 3: Identify Old AR Percentage

In the example:

91–120 + 120+

= $130,000

Percentage:

$130,000 ÷ $600,000 × 100 ≈ 21.7%

This helps management monitor how much AR has moved beyond 90 days.

Step 4: Segment by Payer

Next, ask:

Which payers hold the most AR?

For example:

Then review age distribution within each payer.

Payer A may have the largest AR simply because it represents the largest volume.

Payer B may be more concerning if most of its AR is 120+.

Step 5: Segment by Denial Category

Review which denial categories are driving old AR.

For example:

This tells you where to focus root-cause analysis.

Step 6: Identify High-Dollar Accounts

Sort by:

Outstanding Balance — Highest to Lowest

Review:

• Claim age
• Denial
• Filing deadline
• Last action
• Recoverability

High-dollar accounts should rarely remain untouched.

Step 7: Identify Claims With No Recent Follow-Up

Filter for:

• No notes
• No recent activity
• Follow-up overdue

These may represent workflow gaps.

Step 8: Identify Deadline-Sensitive Accounts

Create a high-priority queue for:

• Filing deadlines
• Appeal deadlines
• Reconsideration deadlines
• Authorization-related deadlines

These should normally be worked before routine status calls.

Step 9: Identify Payer Processing Delays

Some claims may simply be pending.

Before calling repeatedly:

• Check payer portal
• Review processing timeframe
• Review last action
• Confirm expected follow-up date

Not every open claim needs immediate intervention.

Step 10: Work the Highest-Risk Queue First

A practical order might be:

1. Deadline-sensitive claims

2. High-dollar denials

3. Claims with no payer record

4. 120+ high-balance AR

5. 90+ unresolved denials

6. Authorization/eligibility claims with clear resolution path

7. Underpayments

8. Routine pending claims

The exact order can vary by organization.

What About 0–30 Day AR?

New AR should not be ignored.

But not every new claim requires manual follow-up.

For example:

If the payer normally processes within 20–30 days and the claim is:

10 days old

with:

Accepted status

it may simply need time.

However, new claims should still be monitored for:

• Rejections
• Missing payer acceptance
• Authorization problems
• High-dollar exposure

What About 31–60 Day AR?

This is often where proactive follow-up becomes more important.

Review:

• Payer acceptance
• Claim status
• Pending reasons
• Denials
• Payment
• Documentation requests

Claims should not automatically drift into 60+ without understanding their status.

What About 61–90 Day AR?

At this stage, claims deserve more attention.

Questions include:

• Why is this still open?
• Has the claim been denied?
• Is an appeal required?
• Is follow-up overdue?
• Is there an enrollment issue?
• Is payment missing?

The objective is to prevent these claims from becoming 90+ or 120+.

What About 91–120 Day AR?

These claims are becoming more risky.

Priority should increase for:

• High balances
• Active appeals
• Filing issues
• Reprocessing
• Underpayments
• Authorization denials

At this stage, repeated generic status calls are often not enough.

There should be a clear resolution plan.

How to Work 120+ AR

120+ AR deserves a deeper review.

A useful structure is:

1. Confirm Recoverability

Is the claim still recoverable?

2. Review Complete History

• Original submission
• Rejections
• Denials
• Calls
• Appeals
• Documentation

3. Identify the Real Root Cause

Do not rely only on the latest note.

4. Escalate When Necessary

Some claims may require:

• Supervisor
• Client
• Coding
• Credentialing
• Authorization
• Provider documentation

5. Determine Final Action

Possible outcomes:

• Payment
• Appeal
• Corrected claim
• Reprocessing
• Adjustment
• Patient transfer when appropriate
• Final write-off when authorized

Old AR should not remain open indefinitely without a defined next step.

120+ AR Review Questions

For each account, ask:

• Why is this still open?
• What was the original cause?
• What was the latest payer response?
• Is there a deadline?
• Is documentation available?
• Is escalation needed?
• Is recovery still realistic?
• What is the next action?
• When should follow-up occur?

Every old account should have a clear reason for remaining open.

High-Dollar + Old AR

One of the most important combinations is:

High balance + high age

For example:

$25,000

145 days old

This account should receive immediate review.

Potential issues could include:

• Appeal pending
• Provider enrollment
• Authorization
• Medical necessity
• Underpayment
• COB

Large old claims should rarely sit in routine queues without escalation.

Low-Dollar Old AR

Low-dollar claims still matter.

However, AR teams have limited time.

Organizations may use:

• Automated workflows
• Batch corrections
• Payer portals
• Threshold-based prioritization

to handle low-value claims efficiently.

The approach should balance:

cost of collection vs recoverable value

without violating contractual or legal obligations.

AR Prioritization by Risk

You can think about claims in four groups.

High Risk / High Value

Example:

• $10,000
• Appeal deadline in 7 days

Immediate priority

High Risk / Low Value

Example:

• $100
• Filing deadline in 3 days

Still important because right may expire.

Low Risk / High Value

Example:

• $15,000
• Payer accepted and processing within normal timeframe

Monitor closely but may not need immediate call.

Low Risk / Low Value

Example:

• $50
• 20 days old
• Pending normally

Lowest manual priority.

This framework helps allocate time intelligently.

AR Prioritization by Denial Type

Some denial categories need faster attention than others.

Timely Filing

High urgency because rights may expire.

Authorization

May require immediate documentation or appeal.

Medical Necessity

Can require records and longer preparation.

COB

Often resolvable through insurance verification.

Duplicate

Review existing claim before resubmission.

Coding

May require coding team review.

Enrollment

May require escalation outside AR.

Different denials require different workflows.

AR Prioritization by Payer Behavior

Payer behavior matters.

Suppose:

Payer A

Usually processes corrected claims within 10 days.

Payer B

Usually takes much longer.

Follow-up timing should reflect known payer processing periods.

Do not call every payer on the same schedule.

AR Prioritization by Specialty

Specialty also matters.

For example:

Behavioral Health

May have:

• Authorization
• Visit limits
• Mental health benefits

Pain Management

May have:

• Procedure bundling
• Laterality
• Authorization
• Modifier issues

DME

May have:

• Medical necessity
• Documentation
• Supplier requirements

Surgery

May have:

• Global periods
• High-value claims
• Authorization
• Complex modifiers

AR strategy should reflect specialty-specific risk.

Root-Cause Analysis in AR

Working a claim means solving the account.

Managing AR means understanding why groups of claims remain unpaid.

Suppose the aging report shows:

$80,000 in authorization denials

Do not simply work 100 separate accounts.

Ask:

• Which procedures?
• Which payer?
• Which provider?
• Which location?
• Were authorizations obtained?
• Did CPT change?
• Were units exceeded?

This can reveal the operational source.

Example: Eligibility Root Cause

The report shows:

40 claims denied for inactive coverage

Further analysis reveals:

All belong to one insurance plan.

The front desk may be selecting an outdated plan in the system.

Fixing the source can prevent future denials.

Example: Clearinghouse Root Cause

The report shows many claims aged 60+ with no payer record.

Investigation reveals:

All had clearinghouse rejection for the same rendering provider error.

The issue may be provider configuration, not AR follow-up.

Example: Payment Posting Root Cause

The aging report shows high outstanding insurance AR.

But payer portals show claims already paid.

The problem is:

Payment posting backlog

not payer nonpayment.

Calling payers would waste time.

How to Use CARC and RARC in AR Prioritization

When a claim is denied, review:

• Group code
• CARC
• RARC
• Paid amount
• Adjustment
• Patient responsibility

These help identify why the payer processed the claim the way it did.

For example:

A timely filing denial should be routed differently from:

• Deductible
• Duplicate
• Bundling
• Medical necessity

Read:

CARC and RARC Codes Explained: A Beginner's Guide to Medical Billing Denials

How to Prioritize by CARC/RARC

A practical approach may be:

Deadline-sensitive CARCs

Work quickly.

Documentation-related denials

Gather missing records.

Duplicate denials

Check original claim.

Bundling denials

Review coding.

Patient responsibility

Confirm posting.

The code itself does not decide priority.

It helps classify the work.

How to Analyze Claim Notes

Before calling the payer, read previous notes.

Look for:

• Last payer response
• Reference number
• Claim number
• Appeal status
• Processing time
• Documentation request
• Follow-up date

Poor note review leads to repeated work.

For example:

Previous note:

Appeal submitted. Allow 30 business days.

If only five days have passed, another payer call may not be useful.

Good AR Documentation

A useful note should explain:

What happened

What was found

What action was taken

What happens next

Example:

Payer portal reviewed. Claim denied for authorization mismatch. Authorization #A123 valid for DOS and CPT, but rendering provider differs from claim. Account referred for authorization/provider review. Appeal deadline 11/15/2026. Follow-up scheduled in 5 days.

That note supports prioritization.

Weak AR Documentation

Examples:

Called insurance.

Claim denied.

Follow up later.

These notes do not help the next representative understand:

• What happened
• Why
• What should happen next

Good documentation improves the entire AR workflow.

Daily AR Work Strategy

A structured daily routine can improve performance.

For example:

Start of Day

Review:

• Deadline queue
• High-dollar accounts
• Escalations
• Overdue follow-ups

First Work Block

Handle:

• Appeal deadlines
• Filing deadlines
• High-value denials

Second Work Block

Handle:

• 120+ AR
• 90+ AR
• Complex accounts

Third Work Block

Handle:

• Routine payer follow-ups
• Pending claims
• Lower-balance accounts

End of Day

Review:

• Unresolved escalations
• Follow-up dates
• Documentation completeness

This is generally more effective than randomly choosing accounts.

Example AR Priority Queue

Imagine this worklist:

A reasonable priority might be:

1. Claim A — immediate deadline.

2. Claim C — no payer record and filing risk.

3. Claim D — aged denial with potential recovery.

4. Claim B — old but low value; review status.

5. Claim E — high value but currently within normal processing.

This demonstrates why age alone is insufficient.

How to Prioritize Appeals

Appeals can be prioritized by:

• Deadline
• Balance
• Strength of evidence
• Denial type
• Documentation readiness

For example:

A $3,000 authorization denial with complete authorization documentation may be a strong appeal candidate.

A $15,000 denial with no documentation and expired appeal rights may have lower practical recovery potential.

How to Prioritize Corrected Claims

Corrected claims should be reviewed for:

• Filing deadline
• Original claim number
• Correction reason
• Supporting documentation
• Payer submission method

Do not submit corrected claims simply because the original claim denied.

There must be something valid to correct.

Corrected Claim vs Appeal

A useful rule:

Corrected Claim

The original claim information was incorrect.

Appeal

The original claim was correct, but payer decision is being challenged.

Confusing the two can waste valuable time.

How to Prioritize Underpayments

Underpayment queues can be prioritized by:

• Dollar variance
• Contract confidence
• Volume
• Payer
• Time limit for dispute

A small recurring underpayment across hundreds of claims may be financially significant even if each individual amount is small.

High-Volume Low-Dollar Issues

Suppose one payer underpays:

$10 per claim

That may seem minor.

But across:

5,000 claims

the impact is:

$50,000

This is why AR analysis should consider both:

individual value

and

pattern volume.

AR Aging and KPIs

Aging analysis connects directly to RCM metrics such as:

• Days in AR
• AR over 90 days
• AR over 120 days
• Denial rate
• Recovery rate
• Net collection rate

For more information, read:

Medical Billing KPIs Explained: Clean Claim Rate, Denial Rate, Days in AR & More

What Is Days in AR?

Days in AR estimates how much outstanding AR exists relative to average daily charges.

It provides a high-level measure of collection speed.

But it should not replace aging analysis.

A single Days in AR number does not tell you:

• Which payer is slow
• Which denial is growing
• Which claims are near deadlines

The aging report provides deeper operational detail.

AR Trend Analysis

Compare:

• Current month
• Previous month
• Previous quarter
• Same period last year

Ask:

• Is total AR increasing?
• Is 120+ increasing?
• Which payer is worsening?
• Which denial category is growing?

Trends matter more than one isolated snapshot.

Example Trend

Month 1:

120+ AR = $50,000

Month 2:

120+ AR = $65,000

Month 3:

120+ AR = $90,000

This is a warning sign.

Even if total AR remains stable, old AR is increasing.

Management should investigate why.

New AR vs Old AR

A strong RCM team should manage both.

If all effort goes toward old AR:

New claims may develop avoidable problems.

If all effort goes toward new claims:

Old balances may become unrecoverable.

The strategy should include:

prevention + follow-up + recovery

AR Work Queue Design

Instead of one giant work queue, organizations can create separate queues such as:

• Filing risk
• Appeal deadline
• High-dollar
• 120+
• 90–120
• Authorization
• Eligibility
• COB
• Coding
• Enrollment
• Underpayment

This allows specialists to work similar problems efficiently.

Why Specialized Queues Can Help

A representative working 50 authorization denials may become faster at:

• Reviewing auth details
• Identifying mismatch patterns
• Preparing appeals

than someone switching constantly between unrelated claim types.

However, specialization should not prevent broader RCM understanding.

Escalation Criteria

Some claims should be escalated rather than repeatedly worked at the same level.

Examples:

• High-dollar unresolved claim
• Repeated payer processing error
• Provider enrollment issue
• Contract dispute
• Complex medical necessity denial
• Final appeal stage
• Client documentation required

A good AR representative knows when escalation is appropriate.

When Not to Call the Payer

A payer call may not be needed if:

• Portal provides complete claim status.
• Claim is still within stated processing time.
• Appeal was recently submitted.
• Clearinghouse shows claim never reached payer.
• Internal documentation is missing.
• Coding review is required first.

Calling insurance is a tool.

It is not the first answer to every AR problem.

Payer Portal vs Phone Call

Use payer portals when they provide:

• Claim status
• Claim number
• Denial reason
• EOB
• Appeal status
• Payment information

Phone calls may be useful when:

• Status is unclear
• Additional explanation is needed
• Portal lacks information
• Escalation is required

Efficient AR teams use both appropriately.

AR Follow-Up Checklist

Before working an account:

• Correct patient?
• Correct payer?
• Correct DOS?
• Claim submitted?
• Clearinghouse accepted?
• Payer accepted?
• Claim number available?
• Paid?
• Denied?
• Pending?
• Filing deadline?
• Appeal deadline?
• Previous notes reviewed?
• What is the exact next action?

This prevents unnecessary work.

AR Prioritization Checklist

For every claim, ask:

Risk

• Filing deadline?
• Appeal deadline?

Value

• High balance?
• High volume pattern?

Age

• 90+?
• 120+?

Status

• Not on file?
• Denied?
• Pending?
• Paid incorrectly?

Recoverability

• Documentation available?
• Authorization available?
• Appeal rights open?

Root Cause

• Front end?
• Coding?
• Enrollment?
• Payer?
• Posting?

Action

• Call?
• Correct?
• Appeal?
• Escalate?
• Adjust?

This creates a consistent decision-making process.

Common AR Prioritization Mistakes

Avoid:

• Working strictly oldest to newest
• Working only high-dollar claims
• Ignoring filing deadlines
• Ignoring appeals
• Calling payer before checking clearinghouse
• Repeating the same follow-up
• Ignoring underpayments
• Ignoring payer trends
• Ignoring provider enrollment problems
• Poor documentation
• Leaving difficult claims untouched

Strong AR is about intelligent prioritization.

Mistake: Only Working 120+ AR

Old AR matters.

But if newer denials are ignored, today's 30-day claims become tomorrow's 120+ claims.

AR strategy should prevent new aging while resolving old balances.

Mistake: Only Working High-Dollar Claims

High balances deserve attention.

But large numbers of smaller claims can add up to significant revenue.

Balance thresholds should be used intelligently, not blindly.

Mistake: Working Every Claim the Same Way

A:

Timely filing denial

should not be worked like:

Patient deductible

or:

Claim not on file

Each category requires a different approach.

Mistake: Repeatedly Calling Without Action

Example:

Day 1:

Claim denied for authorization.

Day 20:

Claim still denied for authorization.

Day 40:

Claim still denied for authorization.

Nothing changed.

The missing step is:

Investigate authorization.

AR follow-up should move the claim toward resolution.

What Makes a Strong AR Representative?

A strong AR representative does not simply ask:

What is the claim status?

They ask:

Why is this claim still open?

Then:

What is the next action that will move it toward resolution?

That is the difference between:

status checking

and

AR management.

AR Interview Question: How Do You Prioritize Claims?

A strong answer could be:

I do not prioritize only by age. I first review filing and appeal deadlines, then consider balance, claim age, denial reason, payer, last follow-up, and recoverability. High-dollar claims, claims approaching deadlines, no-record claims, and 90+ or 120+ unresolved denials usually receive higher priority. I also review payer and denial trends so systemic problems can be escalated rather than working every claim individually.

Interview Question: Do You Work Oldest Claims First?

A strong answer:

Old claims are important, but I would not always work strictly oldest first. A newer high-dollar claim with an appeal deadline in five days may be more urgent than a small 150-day claim that is already processing. I prioritize based on risk, financial impact, age, deadline, and recoverability.

Interview Question: How Do You Work 120+ AR?

A strong answer:

I review the complete claim history, confirm whether the balance is still recoverable, identify the original root cause, check filing and appeal rights, and determine whether the account needs payer follow-up, corrected billing, appeal, documentation, enrollment review, escalation, or final adjustment. I avoid leaving old accounts open without a defined next action.

Interview Question: How Do You Handle High-Dollar AR?

A strong answer:

I review high-dollar claims early because of their financial impact, but I also consider deadlines and claim status. I verify the submission history, denial reason, payer processing, documentation, authorization, and previous follow-up. If the issue requires another department or escalation, I route it quickly rather than allowing the balance to continue aging.

Interview Question: What Would You Do if a Claim Is 100 Days Old but Payer Says It Was Never Received?

A strong answer:

I would review the original claim submission, clearinghouse acceptance, payer acknowledgment, payer ID, and any claim number. I would also check the payer's timely filing limit. If the payer genuinely never received the claim, I would determine whether correction and resubmission are still allowed. If we have evidence of timely payer receipt, I would preserve that evidence and follow the payer's appropriate dispute process.

Interview Question: Which Is More Important—Age or Balance?

A strong answer:

Neither should be used alone. I would consider age, balance, filing or appeal deadlines, denial reason, payer, and recoverability together. A high-balance claim may deserve priority, but a smaller claim can become more urgent if its filing rights are about to expire.

How to Show AR Aging Experience on Your Resume

Instead of:

Worked AR aging.

Use something more specific:

Analyzed insurance AR aging reports and prioritized claims based on balance, age, filing and appeal deadlines, denial reason, payer status, and recoverability.

Another example:

Managed 90+ and 120+ AR by reviewing claim history, clearinghouse status, payer denials, appeals, corrected claims, and follow-up deadlines.

For senior roles:

Identified payer and denial trends within aging reports and escalated recurring authorization, enrollment, coding, and payment issues for root-cause resolution.

Only include responsibilities you actually performed.

How Team Leads Should Analyze AR Aging

Team Leads should move beyond account-level work.

Review:

• Total AR
• 90+ AR
• 120+ AR
• High-dollar accounts
• Payer trends
• Denial categories
• Staff work queues
• Follow-up gaps
• Escalations

Then ask:

Where is the risk concentrated?

This helps assign resources more effectively.

How Managers Should Analyze AR Aging

RCM managers should connect aging to upstream processes.

For example:

High authorization AR

Review authorization workflow.

High claim-not-on-file AR

Review clearinghouse/rejection process.

High enrollment AR

Review credentialing.

High underpayment AR

Review contracts/payment variance.

AR reports can reveal operational problems across the entire revenue cycle.

AR Aging and Root-Cause Prevention

The ultimate goal is not simply to collect old AR.

The goal is to reduce the creation of avoidable old AR.

For example:

If 30% of 120+ AR results from authorization issues:

Improve authorization workflow.

If many old claims were clearinghouse rejects:

Improve rejection monitoring.

If payer payments are unposted:

Fix payment posting backlog.

Good AR analysis improves both:

collections today

and

claim quality tomorrow.

AR Aging Daily Workflow Example

A practical daily routine could be:

8:00–8:30

Review deadlines and escalations.

8:30–10:30

High-dollar / filing-risk claims.

10:30–12:00

120+ and 90+ AR.

12:00–1:00

Documentation / appeal preparation.

1:00–3:00

Routine payer follow-up and pending claims.

End of shift

Update notes and next-follow-up dates.

The exact schedule depends on workload, but the principle is:

Work risk before routine volume.

Weekly AR Review

A weekly team review might include:

• Total AR
• 90+ balance
• 120+ balance
• Top payers
• Top denial categories
• High-dollar claims
• Filing-risk claims
• Appeal backlog
• Payment posting backlog
• Escalations

This turns aging into an active management tool.

Monthly AR Review

Monthly analysis may examine:

• Aging trend
• Days in AR
• Denial trend
• Payer performance
• Recovery
• Write-offs
• Underpayments
• Team productivity
• Quality

The objective should be to understand:

Are we improving or simply moving claims between aging buckets?

How to Know if AR Is Improving

Positive signs may include:

• Lower 120+ AR
• Lower 90+ AR
• Fewer filing denials
• Fewer unresolved rejections
• Faster appeal resolution
• Better payment posting
• Improved recovery

However, always consider changes in:

• Volume
• Specialty
• Payer mix
• Charges

Raw balances alone can be misleading.

What Freshers Should Learn From an Aging Report

If you are new to AR, first learn:

1. Aging buckets
2. Insurance vs patient balance
3. Claim status
4. Denial reason
5. Submission history
6. Last follow-up
7. Next action

Do not worry about advanced AR strategy immediately.

Learn how one claim moves through the workflow.

What Experienced AR Representatives Should Learn

Experienced professionals should be able to identify:

• Deadline risk
• Financial priority
• Payer trends
• Denial patterns
• Underpayments
• Enrollment issues
• Workflow gaps
• Root causes

This is where AR becomes an analytical role rather than only a follow-up role.

What Senior AR Representatives Should Learn

Senior AR professionals should be able to:

• Prioritize large work queues
• Escalate complex claims
• Support junior staff
• Analyze 120+ AR
• Identify payer patterns
• Review denial trends
• Improve account documentation
• Recommend process changes

These skills prepare professionals for leadership roles.

AR Aging Quick Reference

A simple decision framework:

Claim approaching deadline?

Work immediately.

High-dollar denied claim?

Prioritize.

Claim not on payer file?

Check submission and timely filing.

120+ unresolved claim?

Deep review and escalation.

90+ denial?

Define resolution path.

Pending within normal payer timeframe?

Schedule appropriate follow-up.

Patient responsibility?

Verify adjudication and secondary coverage first.

Underpayment?

Compare expected vs actual reimbursement.

This framework can help organize daily AR work.

The Most Important AR Prioritization Rule

Do not ask only:

Which claim is oldest?

Ask:

Which claim is most at risk, most valuable, most recoverable, and closest to losing its recovery rights?

That question leads to much stronger AR decisions.

Final Thoughts

An AR aging report is much more than a list of unpaid claims.

It is a map of where revenue is delayed, where financial risk is increasing, and where operational problems may be occurring.

A strong AR representative does not work claims randomly.

They prioritize based on:

• Filing deadlines
• Appeal deadlines
• Balance
• Age
• Denial reason
• Claim status
• Payer
• Recoverability
• Last follow-up
• Root cause

The goal is not simply to make more calls.

The goal is to move outstanding claims toward appropriate resolution.

For example:

Claim not on file
→ investigate clearinghouse.

Authorization denial
→ review authorization.

Underpayment
→ review contract/payment.

120+ claim
→ review complete history.

Timely filing denial
→ locate proof of timely filing.

Enrollment denial
→ escalate provider enrollment issue.

This is what separates routine claim follow-up from professional AR management.

For beginners, start by learning how to read the aging report.

For experienced AR representatives, learn to recognize patterns and prioritize risk.

For senior and leadership roles, use aging data to identify systemic problems across the entire Revenue Cycle Management process.
