Denial appeals: what to include and when to appeal

When a claim denies, there are usually three options: correct and resubmit, appeal, or write it off. Choosing the right one saves time. A corrected claim is faster when the problem was a simple error on your side. An appeal is the right path when you believe the payer's decision was wrong.

When to correct instead of appeal

If the denial came from a wrong code, a missing modifier, an outdated member ID, or similar errors, fix the claim and resubmit it as a corrected claim, following the payer's rules. Appealing a claim that simply had wrong information rarely helps.

When to appeal

• The payer says the service was not medically necessary, and documentation supports it.
• The payer applied a bundling edit, and the services were truly separate and documented.
• The payer says authorization was missing, and you have proof it was obtained.
• The payer paid less than your contract or fee schedule allows.
• The payer says the claim was filed late, and you have proof of timely submission.

What a strong appeal includes

1. The payer's appeal form, if it has one, fully completed.
2. Patient, claim, and date of service details, with the claim number.
3. A short letter stating what was denied, why you believe the decision is wrong, and what you are asking for.
4. Supporting documentation, such as the relevant notes, test results, authorization number, or proof of timely filing.
5. References to the payer's own policy, coverage guidelines, or your contract where they support your case.
6. A contact name and number for follow up.

Keep the letter clear and specific. Reviewers handle many appeals, and a focused argument with the right documents is easier to approve.

Watch the deadlines

Every payer sets a deadline for appeals, often counted from the date of the denial notice. Medicare has a set appeal process with specific timeframes for each level. Commercial plans and Medicaid plans set their own. Track the deadline for every denial you plan to appeal.

Follow through

Record when the appeal was sent, how, and when to expect a response. Follow up if you hear nothing. If the first appeal is denied, check whether a further level of appeal is available and whether it is worth pursuing.

Learn from every appeal

Track which denials you appeal and how they turn out, by payer and by reason. If the same denial keeps needing an appeal, the fix may be upstream, in documentation, authorization, or coding.

A quick example

A claim for two procedures on the same day denies as bundled. The note shows the procedures were done on different sites for different problems. The practice sends a short appeal letter explaining the separate sites, attaches the note, and cites the payer's own modifier policy. The appeal is approved, and the practice also updates its coding rule so the correct modifier is added next time.

Where Afiable helps

Afiable reviews denials, corrects what can be corrected, appeals where appropriate with payer specific requirements, and tracks outcomes so repeat denials go down. Book a free audit and we will review a sample of your denials and show you which are worth appealing.
