# CARC 226 denial code dental Answer: On a dental remittance, CARC 226 means: The payer asked the billing or rendering provider for information and never got a usable answer — nothing arrived, it arrived too late, or what arrived did not cover the question. Like 252, its own definition requires an accompanying remark code. 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. The code's own definition requires an accompanying remark code, so a remittance carrying it without one is incomplete. No source read for this page pairs a specific remark code with it. Dentovio's appealability verdict — depends: check the facts first. Whether the information can still be supplied is a payer-contract question, not something the code answers. Find the original request, establish what was sent and when, and ask the payer in writing what window remains before treating the balance as final.

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)
