Official X12 description

“The benefit for this service is included in the payment/allowance for another service/procedure that has already been adjudicated.”

What CARC 97 actually means

CARC 97 is a bundling denial — the payer is saying the service you billed is considered part of another service it already paid. The most common drivers are NCCI Procedure-to-Procedure (PTP) edits, the global surgical package, E/M-bundled-with-a-procedure rules, and payer-specific bundling policies. When two services are genuinely distinct, a distinct-procedural-service modifier (59, XE, XS, XP, XU) or modifier 25 on an E/M solves the problem — provided documentation supports the distinction.

Common root causes

  • NCCI PTP edit between two codes billed on the same date without the override modifier.
  • Service falls inside the global surgical period of an earlier surgery (0-, 10-, or 90-day global).
  • E/M billed on the same day as a minor procedure without modifier 25 and documentation of a separately identifiable E/M service.
  • Payer-specific bundling edit (e.g., commercial-payer bundling of ancillary services into a visit rate).

Prevention checklist

  • Run NCCI PTP and MUE edits at charge entry — ideally at order entry where the clinician can adjust.
  • Educate clinicians on modifier 25 documentation: the E/M must be a significant, separately identifiable service from the procedure.
  • Track global-period dates in the PM system so post-op visits route to the correct no-charge status automatically.
  • Maintain a payer-specific bundling-policy library for commercial payers whose rules diverge from CMS/NCCI.

Appeal strategy — step by step

Most CARC 97 denials clear faster with the right remediation than with a formal appeal. Work the steps in order and escalate only when a lower-effort path has been ruled out.

  1. 1If services were genuinely distinct, submit a corrected claim with the appropriate modifier (25 for E/M, 59 or X{EPSU} for distinct procedure) and the documentation supporting the distinctness.
  2. 2For NCCI edits, confirm the column-2 code is unbundlable — Modifier Indicator 1 allows an override; Modifier Indicator 0 does not.
  3. 3For global-package disputes, include the op note showing the current service is unrelated to the prior surgery (consider modifier 24, 58, 78, or 79 as appropriate).
  4. 4Cite the specific section of the payer's bundling policy or the NCCI Policy Manual when the distinction hinges on policy language.
Sample appeal-letter language for CARC 97
[Provider letterhead] Re: Appeal of CARC 97 — Claim #{claim_number} Member: {member_name} · Member ID: {member_id} Date(s) of Service: {dos} On {remittance_date} this claim was adjusted with CARC 97: "The benefit for this service is included in the payment/allowance for another service/procedure that has already been adjudicated." We respectfully request reconsideration. The X12 External Code List definition of CARC 97 does not apply to this claim for the following reasons: 1. [Cite the clinical / coding / policy fact that rebuts the adjustment] 2. [Cite the supporting documentation attached — op note, EOB, LCD/NCD citation, NCCI edit indicator, modifier rationale] 3. [Cite the payer's own policy where applicable] Attached: {list supporting documents} Please process payment under the member's benefits. If additional information is required, contact the billing office at {provider_phone} or {provider_email}. Sincerely, {billing_manager_name}, {credentials}

How QuickRCM prevents CARC 97

QuickRCM catches the root causes above before the 837 leaves the clearinghouse:

  • Claim-scrub rules fire on every root cause listed above — the scrub references the same X12 CAS segment logic that drives the denial, so what the payer checks, QuickRCM checks first.
  • When a denial lands, QuickRCM routes it to the correct worker with the documentation bundle already attached (op note, LCD citation, modifier rationale, EOB, primary 835).
  • Appeal templates tuned to each CARC (including this one) pull the supporting facts from the claim and fill the bracketed fields automatically.

Frequently asked questions — CARC 97

What does CARC 97 mean?

CARC 97 is an X12 Claim Adjustment Reason Code. The official definition is: "The benefit for this service is included in the payment/allowance for another service/procedure that has already been adjudicated." In plain English, the payer is telling you cARC 97 is a bundling denial — the payer is saying the service you billed is considered part of another service it already paid. The most common drivers are NCCI Procedure-to-Procedure (PTP) edits, the global surgical package, E/M-bundled-with-a-procedure rules, and payer-specific bundling policies. When two services are genuinely distinct, a distinct-procedural-service modifier (59, XE, XS, XP, XU) or modifier 25 on an E/M solves the problem — provided documentation supports the distinction.

How do I resolve a CARC 97 (CO-97) denial?

Start with the most common root cause: NCCI PTP edit between two codes billed on the same date without the override modifier. First step: If services were genuinely distinct, submit a corrected claim with the appropriate modifier (25 for E/M, 59 or X{EPSU} for distinct procedure) and the documentation supporting the distinctness. See the full remediation and appeal checklist on this page before filing a formal appeal.

Is CARC 97 patient responsibility?

No — CARC 97 is typically carried under CO (Contractual Obligation) or OA (Other Adjustment), which means it is the provider's responsibility, not the patient's. Do not bill the patient unless the 835 CAS group code is PR.

What does CARC 97 look like on an EOB or 835 remittance?

On the 835 ERA, CARC 97 appears in Loop 2110 CAS segment as "CAS*CO*97*{amount}". On a paper EOB the same code prints in the Adjustment/Denial Reason column with the X12 description: "The benefit for this service is included in the payment/allowance for another service/procedure that has already been a…" — usually paired with one or more RARC remark codes in the same remittance line for additional context.

Which RARC is paired with CARC 97?

CARC 97 is commonly observed with RARC M15, M25, N20. The RARC narrows the reason — for example, pointing at a missing modifier, an LCD citation, or a specific policy. Fix the underlying CARC first; the RARC usually clears with the corrected claim.
