# CARC 260 denial code on dental claims > What does denial code CARC 260 mean on a dental claim, and can it be appealed? URL: https://dentovio.com/dental-claim-denial-codes/carc-260 Last verified: 2026-08-30 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. ## Direct answer On a dental remittance, CARC 260 means: The claim was priced under the enhanced Medicaid fee schedule the Affordable Care Act created. It records how the claim was paid; it refuses nothing. 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. No source read for this page pairs a specific remark code with it. Dentovio's appealability verdict — not a denial: nothing to appeal. Nothing to appeal or fix. If the payment amount itself looks wrong, that is a fee-schedule question, worked the way any underpayment is worked. Registry entry: X12 Claim Adjustment Reason Code 260 — in the code set since 2014-01-26; active, with no deactivation date. Read on the list published 2025-11-01. Group code: X12 places no group-code restriction on 260. A group code always travels with a CARC, and it — not the CARC — assigns financial responsibility, so read the one on your remittance rather than assuming. ## What it means in dental context Published almost everywhere as a denial — one widely circulated code list renders it as processed under the enhanced fee schedule and not approved for payment, which the code set does not say. It sits beside 259 in the additional-payment cluster, both dated the same day. There is no provider-enrolment remedy to chase, because nothing was refused. ## Appealability: Not a denial — nothing to appeal The appealability verdicts on these pages are Dentovio's editorial classification. No standards body or payer publishes an appealability taxonomy: X12 defines what a code means, not what to do about it. Each verdict is built from the code's own mechanics and the payer and federal documents cited on the page, and it is a starting point for triage rather than a prediction of any outcome. The code records patient liability or an additional payment rather than a refusal. Verify the amount posted correctly and move on. Nothing to appeal or fix. If the payment amount itself looks wrong, that is a fee-schedule question, worked the way any underpayment is worked. ## What to do 1. Read the line as a pricing statement, not a denial 2. If the amount looks low, work it as a fee-schedule underpayment rather than an appeal ## Remark codes No source read for this page pairs a remark code with CARC 260. X12 defines no CARC-to-RARC pairings at all: payer crosswalks are specific to that payer's own internal reason codes, and the CAQH CORE combination list binds only payers operating inside its business scenarios.
