What to do when you receive this document
- 1
Find the denial reason code
Insurance denials always include a reason code or brief explanation. The most common: not medically necessary, out-of-network provider, prior authorization required, benefit limit reached. The reason determines your appeal strategy.
- 2
Check the appeal deadline
Every denial has an appeal window — typically 30–180 days. Missing it can permanently waive your right to appeal. Find this date first.
- 3
Request your full claim file
You have the right to request a copy of your complete claim file including the clinical guidelines the insurer used to deny. This is essential for building an appeal.

Can I appeal an insurance denial?
Yes, almost always. You have the right to an internal appeal with the insurance company, and if that fails, an external review by an independent third party. For health insurance denials, this is federally required under the ACA.
What is a prior authorization denial?
A prior authorization denial means your insurance company decided a treatment or medication isn't covered without pre-approval. You can appeal by having your doctor submit medical necessity documentation.
What is COBRA and why did I get this letter?
COBRA allows you to keep your employer-sponsored health insurance after leaving a job — at your own expense. The COBRA notice tells you your rights, the cost, and how long you have to elect coverage (usually 60 days).
What if my policy is being cancelled?
A cancellation notice means your policy is ending. Check the reason: non-payment (you can often reinstate by paying), non-renewal (the insurer is choosing not to renew), or underwriting issues. You typically have 30+ days to find alternative coverage.
