Appeal
An appeal is a formal request asking a payer to reverse a denial, arguing with evidence that the original decision was wrong under the plan's own rules.

An appeal is a formal, documented challenge to a payer's adjudication decision. It argues that the claim should be paid as billed, and it carries the evidence for that argument — the clinical documentation, the authorization reference, the contract language, or the proof of timely submission.
An appeal is the right response when the claim was correct and the decision was not. When the claim itself carried an error, the faster and cheaper path is usually to correct and resubmit it rather than to argue it.
In practice
Appeals are governed by deadlines, and a missed deadline generally ends the matter regardless of the merits. Medicare publishes a defined multi-level process; commercial payers set their own levels and windows, usually in the provider contract, so the applicable rules are the ones in that plan's policy rather than a single industry standard.
An appeal is a writing task as much as a billing one: it answers the specific reason the payer gave, rather than restating that the service was performed.
Commonly confused with
- Corrected claim: A corrected claim fixes an error and resubmits; an appeal argues that no error was made. Sending one when the other is warranted usually wastes the deadline.
- Reconsideration: Reconsideration is the name a given payer uses for a particular level of its own process — it is one step within appeals, not a synonym for the whole.
- Grievance: A grievance complains about service or conduct; an appeal contests a coverage or payment decision.
