How to appeal a UnitedHealthcare claim denial
To appeal a UnitedHealthcare denial: confirm the denial reason on the remittance, look up the filing window for the specific product in the verified table below, and send a signed appeal with the evidence that answers the payer's stated reason through the channel the provider manual names. UnitedHealthcare's filing windows differ by product — the commercial window and the government-program windows are not the same — so confirm which product the member's plan is before calendaring the deadline.
Where do you find UnitedHealthcare's appeal deadlines?
Our verified UnitedHealthcare table quotes each published window verbatim from the payer's own provider documentation or the governing regulation, with a link to the source — and rules we could not verify against a primary source are flagged for you to confirm in your provider manual, never asserted.
What should a UnitedHealthcare appeal include?
The claim number, member ID, date of service, and denial code; a one-sentence statement of what you want changed; an argument that answers the stated denial reason; and the attached proof — remittance, records, and any authorization or submission evidence. Keep proof that you filed, and calendar the payer's response clock.
What if the filing window has passed?
Check which product governs the claim before writing it off — different products carry different windows — and consider whether documented payer-caused delay supports a good-cause argument. The timely filing guide covers the submission proof that wins those appeals.
