A coding denial occurs when the payer identifies a problem with diagnosis, procedure, modifier, units, sequencing, bundling, or other coded claim information.
What is a coding denial?

Detailed Answer
Coding denials can result from an actual coding error or from a payer edit that needs further review.
Examples include:
- Invalid or inactive code
- Modifier conflict
- Diagnosis-procedure mismatch
- Bundling edit
- Incorrect units
- Global-surgery edit
The AR team should not change coding independently when clinical coding judgment is required. The account should be routed to qualified coding staff when appropriate.
Key Points to Mention
- Coding denials have multiple causes.
- Not every coding denial means the original coding was wrong.
- Clinical coding changes should be supported by documentation.
- AR and coding teams should coordinate.
Example Scenario
A claim denies because the payer says two procedures are bundled. The account is routed for coding review rather than the AR representative adding modifier 59 without documentation.
Common Mistakes
- Changing codes without documentation.
- Treating all coding denials as billing errors.
- Adding modifiers solely to get payment.
Interview Tip
Show respect for the boundary between AR research and coder judgment.
