Service/equipment/drug is not covered under the patient's current benefit plan. Copy-paste appeal letter with documented overturn rate and attachment checklist for Cigna in Dermatology.
Verify before filing
Filing deadlines, appeal addresses, and policy criteria in this template reflect typical payer behavior at publication. Cigna updates policies frequently and plan-level rules vary by employer group, state, and line of business. Always cross-check the specific deadline and filing address on your EOB, and confirm current Cignamedical-policy language through the payer’s provider portal before submitting an appeal. Overturn-rate language below reflects AAPC-reviewer consensus, not payer-published statistics.
When to use this template
Cigna CO-204 denials in dermatology signal the plan considers the service cosmetic or explicitly excluded. Targets include Botox for non-approved indications, laser hair removal, scar revision without functional impact, and certain topical medications that Cigna classifies as cosmetic.
Attachment checklist
- Ordering provider note with clinical indication
- Prior workup or conservative-care documentation
- Payer medical policy reference citing met criteria
- Retroactive authorization request (if applicable)
Missing any one of these is the single largest cause of appeal denials. Build a pre-filing checklist before you submit.

Verify whether this is a plan-level exclusion (appeal futile) or a specific-indication coverage issue (appeal with correct ICD-10). The EOB or the member's benefit summary will tell you which.

How long do I have to file a CO-204 appeal with Cigna?
180 days from the initial adjudication date for most Cigna plans. Corrected claims (for administrative fixes like missing modifiers or auth numbers) have a different and usually longer window. Always confirm the specific deadline on the EOB for your claim.
What is the typical overturn rate for this denial type?
50-70 percent when documentation clearly maps to covered indication. Success depends heavily on documentation completeness and whether the clinical criteria in Cigna's medical policy are matched point-by-point in the appeal.
Should I file this as a corrected claim or a formal appeal?
CO-204 denials are usually formal clinical appeals. The template below follows the formal-appeal structure. Use a corrected claim only if the fix is administrative (a missing modifier, wrong NPI) rather than clinical.
Can I reuse this template for other payers?
The structure works for any payer, but the filing address, deadline, and policy references are specific to Cigna. Check our other templates for payer-specific versions; we have 50+ payer/code combinations in the directory.
