What is a RARC code in denial management?

A Remittance Advice Remark Code, or RARC, provides additional information that clarifies the payer's adjustment or denial reason.

RARCs supplement the information provided by CARCs.

A RARC may explain missing documentation, payer processing requirements, authorization details, coverage rules, or another condition affecting adjudication.

Some RARCs are informational, while others provide important direction for follow-up.

AR staff should review the CARC and RARC together rather than relying on a single code.

• RARC adds detail to the payer's adjudication.
• It should be interpreted with the CARC.
• Some RARCs are informational.
• Payer context still matters.

A claim denies with a broad CARC, but the accompanying RARC identifies that the payer needs specific documentation. That RARC changes the next action from a generic appeal to a targeted records submission.

• Ignoring RARCs.
• Treating every RARC as a denial by itself.
• Not reviewing payer-specific remarks.

Say that RARC refines the denial reason and can change the correct follow-up action.
