How Do I Respond to a CARC 97 Denial?

The Direct Answer

Respond to a CARC 97 denial by writing an appeal letter that proves your bundled procedure was clinically distinct from the primary code — different anatomic site, separate encounter, or independent clinical decision — and attach operative notes or progress notes as evidence. CARC 97 denials account for roughly 12% of all claim denials in surgical and procedural billing. Modifier 59 alone does not win; payers overturn when documentation shows each service served a separate medical purpose.

How It Works

Identify both CPT codes on the denial and look up the NCCI edit pair in the CMS NCCI Policy Manual. Determine whether your modifier indicator allows a distinct service override. Pull the operative report or procedure note and highlight documentation showing separate anatomic sites, distinct clinical sessions, or independent medical decisions for each code.

Write your appeal referencing the specific NCCI edit, the modifier used, and the clinical evidence proving distinctness. Attach the operative report, original claim, remittance advice, and NCCI policy excerpt. Submit through the payer portal and track the appeal reference number. Denial Appeal Pro automates this by reading your CARC 97 denial and generating NCCI-specific appeal language in under 60 seconds.

What You Get

A bundling-specific appeal letter with both CPT codes identified, the NCCI edit pair referenced, modifier rationale explained, and clinical distinctness arguments mapped to your denial. The letter includes an attachment checklist covering operative notes, original claim, remittance advice, and NCCI policy documentation.

Practices that submit CARC 97 appeals with operative note evidence recover an average of $280 per overturned line item — making these appeals worth the 30-minute manual effort, or the 60-second AI generation step.

Frequently Asked Questions

What does CARC 97 mean on my denial?

CARC 97 means the payer bundled your secondary procedure into the payment for another code on the same date of service. The bundled line item receives zero payment even though both codes were billed.

Which modifier do I need for a CARC 97 appeal?

Modifier 59 or XE, XP, XS, or XU indicates a distinct procedural service. Your appeal must explain why the procedures were clinically separate — different anatomic sites, sessions, or encounters — not just that you appended a modifier.

What documentation wins a CARC 97 appeal?

Operative reports or procedure notes showing each service was performed at a different anatomic site or during a distinct clinical session have the highest overturn rate. Include the NCCI edit pair reference and explain why the bundling edit should not apply.

Can AI write a CARC 97 appeal letter?

Yes. Denial Appeal Pro reads your CARC 97 denial and generates an appeal with NCCI edit references, modifier rationale, and the clinical distinctness language payers expect — in under 60 seconds.
