APPEAL LETTER TEMPLATE

Non-Covered / Benefit Denial Appeal Letter

Use this only when the service is actually a benefit and was mis-categorized, mis-coded, or covered under conditions that were met. If the service is truly excluded, this is patient responsibility — don't appeal a genuinely non-covered claim.

What makes it win

  • Cite the plan's own benefit language showing the service is covered (not excluded)
  • If it was mis-coded, submit the corrected, covered code that accurately describes the service
  • If coverage is conditional, show the condition was met — the diagnosis, the prior therapy, the site of service
  • Distinguish this from a true exclusion so the appeal reads as targeted, not reflexive

RE: Appeal of Non-Covered Denial (CARC 96 / 204)
Patient: [PATIENT NAME]   Member ID: [MEMBER ID]
Claim #: [CLAIM NUMBER]   Date of Service: [DOS]
CPT/HCPCS: [CPT CODE]

To the Appeals Department:

We are appealing the denial of [CPT CODE] as non-covered. This service is a covered benefit under the patient's plan and the denial appears to result from [mis-categorization / a coding issue / an unmet-condition flag].

[PAYER]'s [benefit summary / medical policy number] lists [CPT CODE / this category of service] as covered [when CONDITION]. In this case that condition is satisfied: [DIAGNOSIS / PRIOR THERAPY / SITE OF SERVICE / MEDICAL NECESSITY]. The service is therefore payable, not excluded.

[IF CODING: The service was more accurately described by [CORRECTED CPT], which is a covered benefit. A corrected claim is enclosed.]

We ask that the claim be reprocessed as a covered service. If [PAYER] maintains this is a plan exclusion, please cite the specific exclusion language so we can advise the patient accordingly.

Enclosed: [benefit/policy reference], office note dated [DOS][, corrected claim].

Sincerely,
[BILLING MANAGER NAME], [TITLE]
