Filing deadlines, appeal addresses, and policy criteria in this template reflect typical payer behavior at publication. UnitedHealthcare 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 UnitedHealthcaremedical-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

UHC CO-204 denials in pain management target regenerative and alternative injection therapies: prolotherapy (M0076), platelet-rich plasma (0232T), stem cell injections (Q4081 and similar), and some forms of peripheral nerve stimulation devices.

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.

Pro tip

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.

FAQ

Common questions on this template

How long do I have to file a CO-204 appeal with UnitedHealthcare?

180 days from the initial adjudication date for most UnitedHealthcare 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?

20-35 percent for borderline indications; near 0 for purely investigational. Success depends heavily on documentation completeness and whether the clinical criteria in UnitedHealthcare'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 UnitedHealthcare. Check our other templates for payer-specific versions; we have 50+ payer/code combinations in the directory.
