# CARC 97 denial code dental Answer: On a dental remittance, CARC 97 means: The payer did not pay this line separately because it treated the value as already included in the allowance for another adjudicated service. X12 assigns it no group code, so the group code on the remittance is the payer's choice under its own contract and it, not the CARC, decides who is assigned the balance. Remark codes verified with it: M15, N19. Dentovio's appealability verdict — depends: check the facts first. The cause controls. A policy-stated bundle, such as a buildup folded into a crown without preoperative evidence of separate necessity, is unlikely to change after the fact. A bundling edit applied to genuinely distinct services on different teeth or dates can be contested with charting that shows the separation. Delta Dental's documentation request leads with a pre-operative periapical radiograph and a written report; intraoral photographs support it rather than replace it.

Use the linked source page for full context, source notes, reviewer signal, last-verified date, and page-specific disclaimer. ## Review state Dentovio is an independent publisher — not a payer, the ADA, X12, CAQH CORE, or any government agency. Code meanings and remark-code meanings on this page are Dentovio's own wording, written from the official X12 Claim Adjustment Reason Code and Remittance Advice Remark Code lists and linked back to them; X12 holds the copyright in those lists and its descriptions are not reproduced here. CDT codes are referenced by number only; CDT is the American Dental Association's copyrighted code set and this page does not reproduce ADA descriptors. Appealability verdicts are Dentovio editorial classification, not a standard. Every fact traces to the code steward's registry, a federal rule or manual, a HIPAA operating rule, an association publication, or a named payer's own document — never to a billing blog. This page was drafted with AI assistance and verified against the primary sources linked here. It has not been reviewed by a credentialed dental billing specialist, attorney, or clinician. Educational billing reference only — not billing, legal, or clinical advice. Plan contracts control individual outcomes, and processing policies usually live in the payer's provider manual rather than in the signed agreement. ## Supporting public URLs - [/dental-claim-denial-codes](https://dentovio.com/dental-claim-denial-codes) - [/dental-claim-documentation](https://dentovio.com/dental-claim-documentation) ## Related answers - [California dental practice compliance checklist](https://dentovio.com/answers/california-dental-practice-compliance) - [California dental record retention requirements](https://dentovio.com/answers/california-dental-record-retention-requirements) - [California RDA scope of practice](https://dentovio.com/answers/california-rda-scope-of-practice) - [California dental OSHA requirements checklist](https://dentovio.com/answers/california-dental-osha-requirements-checklist)
