How to Appeal a Health Insurance Claim Denial
Use the denial notice, file the plan’s internal appeal, and only then consider external review or a regulator complaint.
Quick start
Who this is for
- The plan denied or underpaid a claim
- You have a written denial reason
- The provider says the balance is your problem after a denial
Why it matters
- A claim that should be reprocessed as covered
- An external-review right after an internal denial
- A state insurance-department or CMS path if the plan misses its own deadline
Do these first
- Save the denial notice. Open the official source for this step.
- Calendar the deadline on that letter. Complete this step, then continue.
- File the internal appeal. Complete this step, then continue.
- Wait for the written decision. Complete this step, then continue.
- Consider external review only after internal appeal. Open the official source for this step.
Direct answer
Commercial plans generally require an internal appeal before external review. The deadline is on the denial notice — confirm that letter, not a generic timeline. File on the plan portal or at the address printed on the notice. Do not send medical records to MoneyPotential.

What information to gather
- Denial reason as printed. Keeps the appeal specific
- Appeal deadline on the notice. The letter, not this page, controls timing
- Plan type. Chooses state department vs EBSA
Gather only what official claim forms require. Never enter your full Social Security number, bank login credentials, or passwords into MoneyPotential — use official .gov or verified agency portals only.
How to interpret the result
- Confirmed. Official records show a match with your identity and a clear claim or appeal path. Proceed through the verified portal with documentation ready.
- Likely. Records strongly suggest a match, but verification documents or a secondary search step is still required before treating funds as yours.
- Possible. A partial match or related account appears. Keep searching under name variations, former addresses, or related federal/state programs.
- Professional review. Complex ownership, legal estate, tax, or plan-administrator disputes may need a fiduciary advisor, tax professional, or attorney.
If nothing appears
- Confirm the claim number with the plan
- Ask whether a corrected claim from the provider is still pending
- Do not skip internal appeal to file a generic complaint
Deadlines and exceptions
