To report medical malpractice in California, file a complaint with the state licensing board that regulates your provider — the Medical Board of California for MDs, and separate boards for osteopathic physicians, physician assistants, and nurses. You submit a Consumer Complaint Form along with signed medical records authorizations, either through the board’s online BreEZe portal or by mail. Before you start, understand what a complaint actually does: the board can investigate the provider and discipline their license, but it cannot award you money. If financial recovery matters to you, that requires a separate civil lawsuit with its own deadlines, and you can pursue both at the same time.
Board Complaint or Lawsuit: Know Which One You Need
These are two different tracks, and people lose time by assuming one covers the other.
A board complaint is a regulatory action. The Medical Board of California reviews whether a doctor violated professional standards and can impose discipline ranging from a public reprimand to license revocation. The purpose is to protect future patients. You will not receive compensation.
A malpractice lawsuit is a civil case filed in court, where you seek payment for medical bills, lost income, pain, and other harm caused by negligence. It is the only path to money. Filing a board complaint does not start a lawsuit, and filing a lawsuit does not trigger a board investigation. Many people do both because each serves a different goal.
Pick the Right Licensing Board
California routes complaints to different agencies depending on the provider’s license. Sending yours to the wrong one wastes weeks.
- Medical doctors (MDs) — Medical Board of California, under the Medical Practice Act at Business and Professions Code section 2000.1California Legislative Information. California Business and Professions Code Sections 2000-2029
- Osteopathic physicians (DOs) — Osteopathic Medical Board of California.2California Legislative Information. California Business and Professions Code Chapter 5 Article 21
- Physician assistants — Physician Assistant Board, which investigates quality of care, inappropriate prescribing, and impairment.3Physician Assistant Board. Complaint Information
- Registered nurses and certified advanced practice nurses — Board of Registered Nursing. This board cannot investigate physicians, dentists, or vocational nurses.4California Board of Registered Nursing. The Complaint Process
- Hospitals, clinics, nursing facilities, hospices, and home health agencies — California Department of Public Health, Center for Health Care Quality (see the facility section below).5CDPH – CA.gov. Complaint Investigation Process
If you don’t know what license your provider holds, use the Medical Board’s license verification tool at mbc.ca.gov. A name search returns the license type, license number, and any public disciplinary history.6Medical Board of California. License Verification
What to Gather Before You File
Pulling everything together up front saves you from stalled investigations and from the BreEZe system timing out mid-submission.
You’ll need the provider’s full legal name and license number (confirmable through license verification), the dates of the treatment at issue, and the names and addresses of every facility where related care took place. Add the names of any other providers who witnessed what happened or who treated you afterward.
The Medical Board’s Consumer Complaint Form asks you to pick a category: quality of care problems like misdiagnosis or surgical complications, office practice issues like billing fraud or refusal to release records, inappropriate prescribing, provider impairment, sexual misconduct, or unlicensed activity.7Medical Board of California. Consumer Complaint Form 07I-61 A narrative section asks you to describe what happened in chronological order. Stick to facts: what the provider did or failed to do, what harm resulted, and the clinical context. Emotional language doesn’t strengthen a complaint and can slow the review.
You also need signed authorization forms giving the board permission to pull your medical records. Without them, the board cannot obtain evidence and your complaint goes nowhere. The board requires two: one authorizing release of information about the physician you’re complaining about, and one listing every treating facility and provider connected to the complaint. Kaiser care uses a separate Kaiser-specific form.8Medical Board of California. Authorizations for Release of Information Fill every field, including facility names and addresses. The authorization is valid for three years from the date you sign it.9Medical Board of California. Physician/Provider/Facility Authorization for Release of Information
Attach whatever supporting documents you have: medical records, photographs, billing statements, correspondence with the provider, police reports, or autopsy and toxicology reports if applicable.7Medical Board of California. Consumer Complaint Form 07I-61
How to Submit the Complaint
Two options: online or by mail. The board does not accept complaints by email because of security concerns.
Online is faster. Save your completed authorization forms to your computer first, because the BreEZe portal may time out if you pause to fill them in during submission. On the BreEZe page, click “File a Complaint” under the Consumers heading and follow the prompts to upload your complaint and authorizations.10Medical Board of California. BreEZe Complaints
By mail, send the complaint form, signed authorizations, and supporting documents to the Medical Board of California, 2005 Evergreen Street, Suite 1200, Sacramento, CA 95815.11Medical Board of California. Contact Processing takes longer than electronic filing.
What Happens After You File
The Central Complaint Unit does the initial intake. CCU staff decide whether the allegations fall within the board’s jurisdiction and whether the facts suggest a possible violation of the Medical Practice Act.12Medical Board of California. Complaint Process You should receive a letter confirming receipt. Urgent complaints involving sexual misconduct or provider impairment can be referred for investigation immediately.
If a medical consultant reviewing the file thinks a violation may have occurred and more investigation is warranted, the case is referred to the Health Quality Investigation Unit. HQIU investigators may contact you for clarification, interview witnesses, and arrange for independent expert medical review. The board sends a letter when this referral happens.12Medical Board of California. Complaint Process
Timelines vary widely. Simple cases resolve in a few months. Complex ones involving multiple providers or expert review take a year or more. There is no mechanism to speed this up. If the board finds a violation, outcomes range from a public letter of reprimand to probation with conditions, license suspension, or revocation.
If You Also Want Compensation: Lawsuit Deadlines
A board complaint will never put money in your pocket. For that you need a civil malpractice lawsuit, and the clock is already running.
California Code of Civil Procedure section 340.5 gives you the shorter of two deadlines: one year after you discover (or reasonably should have discovered) the injury, or three years from the date the injury actually occurred.13California Legislative Information. California Code CCP 340.5 The three-year outer limit is hard. Missing it typically ends the case.
Narrow exceptions exist. The three-year deadline can be extended if you can prove the provider committed fraud, intentionally concealed the malpractice, or left a foreign object in your body that had no medical purpose. For children injured before age six, the deadline runs until the child’s eighth birthday or three years from the injury, whichever is longer.13California Legislative Information. California Code CCP 340.5
The 90-Day Pre-Suit Notice
Before you can file a malpractice lawsuit, you must give the healthcare provider written notice at least 90 days in advance. The notice has to describe the legal basis for your claim, the nature of your injuries, and your losses. No particular form is required.14California Legislative Information. California Code CCP 364 If you serve this notice within the final 90 days before your statute of limitations expires, the filing deadline extends by 90 days from the date of service. Relying on that cushion means cutting it very close.
Reporting a Hospital or Clinic Instead of a Person
When the problem is institutional rather than individual, the complaint goes to the California Department of Public Health, not a licensing board. CDPH’s Center for Health Care Quality handles complaints about licensed facilities, including hospitals, skilled nursing facilities, hospices, home health agencies, and clinics.5CDPH – CA.gov. Complaint Investigation Process Typical facility concerns include unsafe staffing levels, sanitary failures, and safety breakdowns at the institutional level.
CDPH does not license individual doctors or nurses, so a facility complaint won’t reach the clinician who treated you. When a hospital physician provided substandard care and the institution’s own practices also contributed, file with the Medical Board about the doctor and with CDPH about the facility. Nothing prevents you from filing with both.
