Reporting medical malpractice in California involves two separate tracks: filing a complaint with the appropriate licensing board to trigger an investigation into the provider, and pursuing a legal claim for compensation. You can do one or both, and they operate independently. The board you report to depends on the type of provider involved, and a lawsuit requires a mandatory 90-day notice before you can file.
Filing a Complaint With the Medical Board
For complaints against medical doctors (MDs), the Medical Board of California’s Central Complaint Unit handles intake. You can submit a complaint online through the state’s BreEZe system, by fax to (916) 263-2435, or by mail to Medical Board of California, ATTN: Central Complaint Unit, 2005 Evergreen Street, Suite 1200, Sacramento, CA 95815-5401. The online route is fastest.
Before you file, gather as much documentation as you can. Dates of treatment, the provider’s name, a written description of what happened, and any records you already have will strengthen your complaint. You’ll likely be asked to sign an Authorization for Release of Medical Information so the board can pull your medical records directly. The board cannot review a physician’s records without patient consent or a subpoena tied to a specific patient, so your authorization is essential to moving the investigation forward.
If you know other patients who experienced similar problems with the same provider, the board encourages you to share that information or have those patients file their own complaints. You can reach the board by phone at 1-800-633-2322.
What Happens After You File
The Central Complaint Unit reviews every complaint to determine whether the allegations fall within the board’s jurisdiction and whether they suggest a possible violation of medical practice law. If the complaint moves forward, staff will request your medical records, ask the physician for a written summary of what occurred, and collect any other relevant documentation, including records from doctors who treated you afterward.
The board has a statutory deadline for taking formal action: it must file charges against a physician’s license within three years of first learning about the alleged misconduct, or within seven years of the incident itself, whichever comes first. That means filing sooner gives the board more time to investigate thoroughly. Complaints that don’t fall within the board’s authority are typically referred to the appropriate agency.
Which Board Handles Your Provider
California licenses different types of healthcare professionals through separate boards, and you need to file with the right one.
- Medical doctors (MDs): Medical Board of California
- Osteopathic physicians (DOs): Osteopathic Medical Board of California, which has its own complaint process at ombc.ca.gov
- Registered nurses and midwives: California Board of Registered Nursing, which accepts complaints online through BreEZe or by mail to PO Box 944210, Sacramento, CA 94244-2100
The Board of Registered Nursing can only investigate RNs licensed by that board. It cannot handle complaints about physicians, dentists, vocational nurses, psychiatric technicians, or other providers licensed by different agencies. If you’re unsure which board oversees your provider, you can look up their license through the BreEZe system at breeze.ca.gov, which shows the licensing board, license status, and any past disciplinary actions.
Reporting a Hospital or Facility
If your complaint involves a hospital, nursing home, or other healthcare facility rather than an individual provider, the California Department of Public Health handles that separately. Anyone can file a complaint, whether you’re the patient, a family member, or a concerned member of the public.
The most direct method is through Cal Health Find, the state’s online database. Search for the facility by name, then select “File a Complaint.” You can also call, fax, or mail a letter to the CDPH district office that oversees the facility in question. A directory of district offices and the counties they cover is available on the CDPH website.
Investigation timelines vary by facility type and severity. Complaints involving hospitals or non-long-term-care facilities that allege an ongoing threat of death or serious harm must be completed within 45 days. For skilled nursing facilities and other long-term care settings, the department must complete investigations within 60 days. The district office will notify you in writing once the investigation wraps up.
Pursuing a Legal Malpractice Claim
A board complaint can result in disciplinary action against a provider’s license, but it won’t get you financial compensation. For that, you need a separate civil lawsuit. California has specific procedural requirements that differ from a standard personal injury case.
The biggest one: you must give the healthcare provider at least 90 days’ written notice before filing suit. Under California Code of Civil Procedure Section 364, no malpractice action can begin without this notice. The letter doesn’t require a specific form, but it must state the legal basis of your claim, the type of loss you suffered, and the nature of your injuries with specificity. If you serve this notice within 90 days of the statute of limitations expiring, the deadline to file your lawsuit extends by an additional 90 days.
The general statute of limitations for medical malpractice in California is one year from the date you discovered (or reasonably should have discovered) the injury, or three years from the date of the injury, whichever comes first. Missing these deadlines typically bars your claim entirely.
Damage Caps Under California Law
California’s MICRA law caps non-economic damages (pain and suffering, emotional distress, loss of enjoyment of life) in malpractice cases. These caps were revised in recent years and are now adjusting upward on a set schedule.
As of January 1, 2026, the cap for non-fatal malpractice cases is $470,000, increasing by $40,000 each year until it reaches $750,000 in 2033. For wrongful death cases, the 2026 cap is $650,000, rising by $50,000 annually to a maximum of $1,000,000 in 2033. These caps apply only to non-economic damages. Economic damages like medical bills, lost wages, and future care costs have no cap.
Board Complaint vs. Lawsuit: Key Differences
Filing a board complaint is free, doesn’t require a lawyer, and focuses on whether the provider violated professional standards. The possible outcomes include license suspension, probation, or revocation, but no money goes to you. A malpractice lawsuit seeks financial compensation but requires meeting strict procedural deadlines, proving the provider’s negligence caused your injury, and navigating the damage caps described above.
You don’t have to choose one path over the other. Many people file a board complaint to protect future patients while simultaneously pursuing a legal claim for their own losses. The board investigation and the lawsuit proceed on separate tracks and don’t depend on each other’s outcomes.
