California's DMHC and CDI give consumers binding independent review, no balance billing, language access rights, and some of the most powerful complaint tools in the country. Most Californians never use them.

Which one you use depends on your plan type. HMO = DMHC. PPO = CDI. Both are free.
Regulates HMOs, Knox-Keene licensed plans, and managed care organizations — including Kaiser Permanente, Blue Shield of CA (HMO), Health Net, Molina Healthcare, LA Care, and most Covered California plans. DMHC runs California's powerful Independent Medical Review program.
Regulates PPO plans, indemnity plans, life insurance, disability insurance, and other non-Knox-Keene products — including Anthem Blue Cross PPO, Aetna PPO, Cigna, and most employer self-funded plan stop-loss policies. CDI handles bad faith investigations and prompt payment violations.
California law gives health insurance consumers rights that don't exist in most other states.
Under the Knox-Keene Act and CA Insurance Code §10169, you have the right to a free, binding Independent Medical Review administered by DMHC. An independent physician — with no financial ties to your insurer — reviews the denial. The IMR decision is legally enforceable against your health plan. DMHC data shows IMR overturns 40–80% of denials depending on category. You can request IMR after your plan denies your internal grievance, or after 30 days if the plan has not responded.
California law (Health & Safety Code §1373.96) gives you the right to continue treatment with an out-of-network provider during transitions — including when your insurer changes networks, when you become newly covered, or when a provider leaves the network mid-treatment. You can request continuity of care for up to 12 months for serious, chronic, or terminal conditions. Your insurer must allow you to complete an ongoing course of treatment.
California's AB 72 and the federal No Surprises Act protect you from unexpected bills from out-of-network providers at in-network facilities. If you receive care at an in-network hospital, facility, or emergency room, out-of-network providers there cannot bill you more than your in-network cost-sharing amount. For emergencies, you can never be billed more than in-network rates regardless of which hospital you visit.
Under California's network adequacy standards, your insurer must maintain a network sufficient to provide timely access to all covered services. If your plan cannot provide a covered service within required time and distance standards — 15 minutes/15 miles for primary care, 30 minutes/30 miles for specialists — you are entitled to an out-of-network provider at in-network cost-sharing. File a DMHC complaint if your insurer claims no in-network providers are available.
Under California Health & Safety Code §1367.04, health plans must provide translated notices, interpreter services, and translated EOBs to enrollees who speak one of the state's threshold languages (Spanish, Chinese, Vietnamese, Korean, Tagalog, and others). If you received a denial notice in a language you don't understand, or were denied interpreter services, that is a separate violation you can raise in your DMHC complaint.
California's IMR process is the fastest and most powerful first move for HMO members.
Submit a formal written grievance (not just a phone call) to your insurer citing the specific denial reason, your policy number, and the medical records supporting your claim. Your plan must respond within 30 days for standard requests and 72 hours for urgent/expedited requests. Keep copies of everything.
For HMO or managed care plan members: file for Independent Medical Review at dmhc.ca.gov or call 888-466-2219. You can request IMR immediately after receiving a denial — you do not need to exhaust multiple levels of internal appeal. Standard IMR takes up to 30 days. Expedited/urgent IMR takes 3 business days. The IMR decision is binding on your health plan.
If you have a PPO, indemnity, or non-Knox-Keene plan, your regulator is CDI (California Department of Insurance) at insurance.ca.gov or 800-927-4357. CDI can investigate improper denials, order claim payments, and refer cases for bad faith investigations. CDI complaints typically resolve in 30–60 days.
California Small Claims Court (limit: $10,000 for individuals) is a powerful tool for smaller denied claims. You can sue your insurer for the denied amount plus consequential damages without an attorney. Insurers frequently settle rather than send executives to small claims court. Filing fee is $30–$75.

Read guide →The DMHC IMR is a free, binding independent review of a denied health insurance claim administered by the California Department of Managed Health Care. An independent physician reviews your case and the decision is legally binding on your health plan. DMHC data shows IMR overturns 40–80% of denials in some categories. File at dmhc.ca.gov or call 888-466-2219.
DMHC (Department of Managed Health Care) regulates HMOs and managed care plans such as Kaiser Permanente, Blue Shield of CA HMO, and Health Net. CDI (California Department of Insurance) regulates PPO plans, indemnity plans, and other commercial insurance. If your plan is an HMO, go to DMHC. If it is a PPO, go to CDI.
Yes. California AB 72 and the federal No Surprises Act protect you from balance billing by out-of-network providers at in-network facilities. You can never be billed more than your in-network cost-sharing for emergency services, or for non-emergency services at in-network facilities without your informed written consent.
Standard IMR takes up to 30 days from the date DMHC receives your complete application. Expedited (urgent) IMR must be completed within 3 business days. You can request expedited IMR if a standard timeline would seriously jeopardize your health or ability to regain maximum function.
Yes. Beyond the administrative process, California recognizes bad faith insurance claims under Brandt v. Superior Court and Insurance Code §790.03. You can pursue small claims court for amounts under $10,000, or file a civil bad faith lawsuit for larger amounts — potentially including punitive damages if the insurer acted unreasonably and in bad faith.
