The Complete Insurance Denial Code Library — What Every Code Means
The ClaimCompass Denial Code Library translates every major insurance denial code and tells you exactly what to do.
Filing with your state insurance commissioner is free, triggers a review, and can force insurer compliance.

Filing a complaint with your state insurance commissioner is one of the most underused tools available to consumers. It is free, it triggers a regulatory review, and it can accelerate resolution in ways that the insurer's own appeals process cannot.
You should consider filing when:
What the commissioner cannot do: they cannot represent you in litigation or guarantee a specific outcome.
Collect your denial letter, your explanation of benefits, your correspondence with the insurer, your insurance policy or summary plan description, and any appeals you have filed.
Go to NAIC.org for a complete directory of state insurance departments. Each state has its own filing process — most now accept online complaints.
Describe the situation clearly and factually. Include dates, policy numbers, claim numbers, and a specific statement of what you believe the insurer did wrong and what law or regulation you believe was violated.
Attach your denial letter, appeals correspondence, and any other relevant documentation.
Most states require the insurer to respond within 30 days. Follow up with the commissioner's office if you do not receive a response within that time frame.
If your insurance is through an employer plan governed by ERISA, your state insurance commissioner has limited jurisdiction. ERISA preempts most state insurance laws for employer-sponsored plans. For ERISA plans, the Department of Labor handles complaints at dol.gov.
ClaimCompass helps you document your situation and generates formal correspondence to support your complaint.
