Denied a Health Insurance Claim in California? Here's How to Fight Back
How long do I have to appeal a denied health insurance claim in California?
In California, you typically have 180 days from receiving a denial to file an internal appeal with your health plan, and generally six months from the final internal denial to apply for an Independent Medical Review through the California Department of Managed Health Care. Check your plan documents and the DMHC's website at dmhc.ca.gov to confirm the specific deadlines that apply to your case.
What is California's Independent Medical Review and how do I apply?
California's Independent Medical Review (IMR) program lets you have a health plan's medical necessity denial reviewed by independent doctors who have no connection to your insurer. It's free to apply, and if reviewers side with you, your plan must cover the service. Apply through the California Department of Managed Health Care at dmhc.ca.gov or by calling 1-888-466-2219.
What if my health insurance appeal is urgent or my health is at risk?
If waiting for a standard appeal decision would seriously jeopardize your health, California allows for an expedited review process. For internal appeals, plans regulated by the DMHC are generally required to respond within 72 hours for urgent situations. You can also contact the DMHC Help Center at 1-888-466-2219 to request an expedited Independent Medical Review if the delay poses an immediate threat to your health.
Can I get help appealing a denied health insurance claim in California if I can't afford a lawyer?
Yes. The Health Consumer Alliance, a network of nonprofit legal aid organizations across California, offers free assistance to residents dealing with health insurance denials and appeals. Their services are available regardless of income in many cases. You can find the regional office serving your area at healthconsumer.org.
Does California's appeals process apply to Medi-Cal denials too?
Medi-Cal has its own separate appeals process, administered through the California Department of Health Care Services rather than the DMHC. If your Medi-Cal coverage or a specific service is denied, you have the right to request a State Fair Hearing through the California Department of Social Services. The DHCS website at dhcs.ca.gov has information on how to start that process.
A denied health insurance claim doesn't have to be the end of the road. California gives patients more than one shot at getting a coverage decision reversed - through their insurer, through an independent review, and through the state's Department of Managed Health Care, which enforces consumer protections for most Californians with private health coverage. Knowing which path to take, and when, makes a real difference in whether you get paid.

First, Understand What Kind of Plan You Have
The process you follow depends on who regulates your plan. Most Californians with employer-sponsored or individually purchased health plans are covered by the California Department of Managed Health Care (DMHC). Some employer self-funded plans, however, fall under federal ERISA rules and are instead regulated by the U.S. Department of Labor - not the state. If you're not sure which applies to you, call your HR department or check the back of your insurance card; the DMHC's Help Center (dmhc.ca.gov) can also help you figure it out. Medi-Cal enrollees have a separate appeals process through the California Department of Health Care Services.
Step One: File an Internal Appeal With Your Insurer
When a claim is denied, your insurer is required to send you a written explanation of the denial - called an Explanation of Benefits, or EOB. Read it carefully, because the reason listed determines your best argument on appeal. Most denials fall into a few categories: the service wasn't deemed medically necessary, the provider was out-of-network, prior authorization wasn't obtained, or the plan considers the treatment experimental.
California law requires health plans regulated by the DMHC to have an internal grievance process in place. You typically have 180 days from receiving the denial to file an internal appeal, though you should confirm that deadline with your specific plan documents. Submit your appeal in writing, and include everything that supports your case: a letter from your doctor explaining why the treatment was medically necessary, relevant medical records, and a copy of the original denial letter. Keep copies of everything you send.
Once you file, the plan is generally required to respond within 30 days for standard appeals, or within 72 hours if your situation is urgent. If your internal appeal is denied, or if the plan doesn't respond within the required timeframe, you have other options.
Step Two: Request an Independent Medical Review
California's Independent Medical Review (IMR) program, administered by the DMHC, is one of the strongest consumer protections in the country. If your insurer denies or delays a service on medical necessity grounds, you can ask the DMHC to have the decision reviewed by independent physicians who have no relationship with your health plan.
To be eligible, you generally need to have already gone through your plan's internal appeal process - or be able to show that doing so would seriously jeopardize your health, in which case the DMHC can expedite the process. You typically have six months from the date of your final internal denial to apply for an IMR. The review is free to you, and if the independent reviewers find in your favor, your health plan is legally required to cover the service.
Apply directly through the DMHC's website at dmhc.ca.gov, or call its Help Center at 1-888-466-2219. The DMHC also has a paper application if you need one mailed to you.

Filing a Complaint With the DMHC
Not every problem fits neatly into the IMR process. If your issue is about billing, customer service, a plan's failure to provide timely care, or a denial that isn't based on medical necessity, you can file a complaint directly with the DMHC through its Help Center. The agency reviews complaints and can intervene with your health plan on your behalf. Complaints can be filed online, by phone, or by mail.
For issues involving plans regulated by the California Department of Insurance rather than the DMHC - such as some indemnity or short-term health plans - the California Department of Insurance (insurance.ca.gov) handles complaints and has its own consumer assistance division. If you're uncertain which agency covers your plan, the DMHC's Help Center is a reasonable first call; they can direct you if they're not the right office.
What to Keep Track of Through the Whole Process
Document everything from the moment you get the denial: the date of the denial letter, the stated reason, the names of any representatives you speak with by phone, and the dates you file each step of your appeal. Health plan grievance processes have strict deadlines, and missing one can cost you the right to appeal. Keep a folder, physical or digital, with every piece of correspondence. If you need help navigating this process and can't afford an attorney, the Health Consumer Alliance (healthconsumer.org) offers free assistance to California residents through a network of legal aid organizations across the state.
