How to appeal a denied health insurance claim

Read the denial, gather support, and use your appeal rights.

  1. 1

    Read the denial reason

    The explanation of benefits states why the claim was denied and the deadline to appeal.

  2. 2

    Gather supporting documents

    Collect medical records and a letter from your doctor explaining medical necessity.

  3. 3

    File an internal appeal

    Submit your appeal in writing before the deadline and keep copies.

  4. 4

    Request an external review

    If the internal appeal fails, an independent external review may be available.
