Your rights

For ACA-compliant individual/group health plans: federal internal appeal / external review rules; for employer self-funded plans: ERISA claims procedure; for other insurance (auto, home, life): state insurance department complaint route.

Internal appeal
You must file your internal appeal within 180 days (6 months) of receiving notice that your claim was denied. The insurer must notify you of a denial within 15 days for prior authorization, 30 days for services already received, or 72 hours for urgent care. The internal appeal itself must be completed within 30 days (service not yet received) or 60 days (service already received); for urgent situations, a decision must come within at least 4 business days, with written notice following within 48 hours.
External review
If the internal appeal is denied, you can request an independent external review; the insurer's final determination must explain how to request one.
