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.
Every state has its own appeal rules, deadlines, and consumer protections. Here is what matters for your location.

Federal law sets a floor for your appeal rights — the ACA,ERISA, MHPAEA, and the No Surprises Act apply everywhere. But states are free to go further, and many do. Your state's insurance commissioner, external review requirements, appeal deadlines, and consumer protection laws can significantly affect your options.
If you are appealing an insurance denial, a VA decision, a government benefit termination, or any official adverse determination, knowing your state's specific rules gives you an advantage.
While federal law sets minimum timelines, some states impose shorter or longer deadlines for specific types of appeals. Always check your denial notice AND your state's specific requirements.
All ACA-compliant plans must provide federal external review. Many states have additional external review requirements with broader eligibility and faster timelines.
Some states have enacted parity laws that go beyond the federal MHPAEA, covering additional plan types or providing stronger enforcement mechanisms.
The strength and responsiveness of state insurance departments varies widely. Some states have aggressive consumer protection divisions with rapid response times. Others are less active.
Many states mandate coverage for specific services — ABA therapy for autism, infertility treatment, eating disorder care — that are not required under federal law.
Some states enacted surprise billing protections before the federal No Surprises Act and maintain state-level protections for situations the federal law does not cover.
File complaints, check insurer complaint records, and access consumer assistance programs. Find your state commissioner at NAIC.org.
Many states have federally funded Consumer Assistance Programs that provide free help with insurance appeals and complaints. Find yours athealthcare.gov/help-center.
Each state designates one or more Independent Review Organizations for external review. Your denial notice must include information on how to access external review in your state.
ClaimCompass is building dedicated state guides covering the specific appeal deadlines, insurance commissioner processes, consumer rights protections, and external review procedures for every state.
