In California, the doctor-patient privilege lets you keep confidential medical communications out of evidence in a legal proceeding, and you — not your doctor — decide whether to assert it. The rules sit in Evidence Code sections 990 through 1007, and they come with limits that catch many patients off guard. The biggest one: the privilege does not apply at all in criminal cases.
You Hold the Privilege, and You Have to Assert It
The patient is the only person who decides whether to keep medical communications confidential or let them into evidence. Under Evidence Code 994, you can refuse to disclose confidential communications with a physician and can stop anyone else from disclosing them.1California Legislative Information. California Evidence Code 994 – Physician-Patient Privilege A doctor subpoenaed to testify cannot share what you told them unless you agree.
If you have a guardian or conservator, that person steps into your shoes and controls the privilege. If you die, the personal representative of your estate takes over.2California Legislative Information. California Evidence Code 993 – Holder of the Privilege This matters in wrongful death and probate matters, where someone may try to subpoena a deceased patient’s records. The estate representative can block disclosure. When every party in a dispute is claiming through the same deceased patient, such as heirs fighting over a will, the privilege disappears.3Justia Law. California Evidence Code 990-1007 – Physician-Patient Privilege
The privilege must be actively claimed. If you have the chance to object to disclosure during a proceeding and say nothing, a court can treat that silence as a waiver.
What the Privilege Covers
Evidence Code 992 defines a confidential communication as information transmitted in confidence during the physician-patient relationship, including anything the physician learns through examination, any diagnosis, and any advice given.4California Legislative Information. California Evidence Code 992 – Confidential Communication Between Patient and Physician That reaches verbal conversations, written records, test results, prescriptions, treatment plans, and digital messages through a patient portal.
You have to actually intend confidentiality. If you bring a friend with no medical role into the exam room, a court could find you didn’t intend what you said in front of them to stay private, and the privilege can collapse for those communications.
“Physician” is defined broadly. It covers anyone authorized to practice medicine in any state or nation, and anyone you reasonably believed was authorized to practice medicine.5California Legislative Information. California Evidence Code 990 – Definition of Physician If you reasonably thought the person you saw was a licensed doctor, the privilege applies even if their license later turns out to have lapsed or been issued elsewhere. Nurses, medical assistants, and technicians working under a physician’s direction are covered too; their presence doesn’t break confidentiality because they’re considered necessary to the consultation.
Therapy Is Protected by a Separate, Stronger Privilege
If you’re asking about therapy, the physician-patient privilege is not the one that governs. California provides a separate psychotherapist-patient privilege under Evidence Code 1014.6California Legislative Information. California Evidence Code 1014 – Psychotherapist-Patient Privilege That distinction matters because the psychotherapist version survives in criminal proceedings; the physician version does not.
“Psychotherapist” is defined broadly to include psychiatrists, licensed psychologists, licensed clinical social workers doing psychotherapy, licensed marriage and family therapists, school psychologists, psychiatric-mental health nurses with master’s degrees, and various trainees and associates working under supervision.7California Legislative Information. California Evidence Code 1010 – Definition of Psychotherapist
The psychotherapist privilege has its own dangerous-patient exception. If a psychotherapist has reasonable cause to believe a patient is dangerous to themselves or others and disclosure is necessary to prevent that danger, no privilege applies.8California Legislative Information. California Evidence Code 1024 – Dangerous Patient Exception Civil Code 43.92 adds the Tarasoff duty: when a psychotherapist learns of a serious threat of physical violence against a reasonably identifiable victim, they must make reasonable efforts to warn that victim and law enforcement.9California Legislative Information. California Civil Code 43.92 – Duty to Protect This duty attaches to psychotherapists as defined in Evidence Code 1010, not to physicians generally.
The Exceptions That Actually Matter
The privilege has more holes than most patients realize. These are the ones most likely to affect you.
Criminal Cases: No Privilege at All
This is the broadest exception and the one that surprises people most. Evidence Code 998 states flatly that there is no physician-patient privilege in a criminal proceeding.10California Legislative Information. California Evidence Code 998 – Criminal Proceeding It is not limited to particular crimes or particular records. If you are a defendant or witness in a criminal case, the prosecution can subpoena your doctor and your medical records, and the physician-patient privilege will not stop it. This is why the separate psychotherapist-patient privilege matters so much to anyone in therapy who faces criminal charges.
You Put Your Own Health at Issue
When you file a lawsuit that puts your physical or mental condition in dispute, you lose the privilege for medical communications relevant to that condition. Evidence Code 996 removes the privilege when the patient, someone claiming through the patient, a beneficiary under a contract with the patient, or a plaintiff suing for the patient’s injury or death has raised the patient’s condition as an issue in the case.11California Legislative Information. California Evidence Code 996 – Patient-Litigant Exception File a personal injury suit claiming back injuries, and the defense can reach records about your back. Courts generally keep this to records relevant to the condition at issue, not your whole medical history.
You Saw the Doctor to Commit a Crime or Fraud
If you sought medical services to further a crime or tort, or to help conceal one after the fact, no privilege attaches. Evidence Code 997 removes the privilege in that situation.12California Legislative Information. California Evidence Code 997 – Crime or Tort Exception Classic examples are seeing a doctor to obtain drugs illegally or fabricating symptoms to support a fraudulent insurance claim.
Mandatory Reports
Information your doctor is legally required to report is not privileged. Evidence Code 1006 removes the privilege for anything the physician or patient must report to a public employee, or that must be recorded in a public office, when those reports or records are open to inspection.13California Legislative Information. California Evidence Code 1006 – Required Reports The biggest category is suspected child abuse. Penal Code 11166 requires physicians and other mandated reporters to report suspected child abuse by telephone immediately, with a written report within 36 hours; failure to report is a misdemeanor carrying up to six months in jail, a $1,000 fine, or both.14California Legislative Information. California Penal Code 11166 – Mandated Reporters Similar duties apply to suspected elder abuse and to certain injuries from firearms or domestic violence.
Commitment and Competence Proceedings
The privilege does not apply in proceedings to involuntarily commit a patient or to place the patient or their property under someone else’s control because of a mental or physical condition.15California Legislative Information. California Evidence Code 1004 – Commitment Proceedings It also does not apply in a proceeding brought by or on behalf of the patient to establish competence.16California Legislative Information. California Evidence Code 1005 – Competence Proceedings In each situation, the patient’s condition is the central question.
Disputes Between You and Your Doctor
When either party breaches a duty owed to the other, the privilege lifts for communications relevant to that breach. The most common setting is medical malpractice. A patient suing their doctor needs the records to prove the claim, and the doctor needs them to defend. Evidence Code 1001 keeps either side from hiding behind privilege.
Professional Licensing Investigations
When a government agency decides whether to revoke, suspend, or restrict a professional license, public employment, or other government-granted authority, the privilege does not apply.17California Legislative Information. California Evidence Code 1007 – Public Entity Proceedings If the medical board investigates a physician’s fitness, patient communications relevant to that inquiry are not shielded.
How You Can Accidentally Waive It
You can lose the privilege by voluntarily disclosing the protected information. Under Evidence Code 912, if the privilege holder voluntarily discloses a significant part of a confidential communication, or consents to someone else disclosing it, the privilege is waived for that communication.18California Legislative Information. California Evidence Code 912 – Waiver of Privilege Consent can be explicit, like signing an authorization form, or implied by conduct, including failing to object when you had standing and opportunity.
Everyday choices can look like waivers in hindsight. Sharing records with an employer for a disability accommodation, submitting them to an insurer for a claim, or discussing a diagnosis in detail on social media can all be treated as voluntary disclosures. Courts generally cabin the resulting waiver to the information you actually released, not your whole history, but the line is not always predictable.
Testifying about your own medical condition is another common path. Describe your injuries on the stand, and the other side can argue you’ve opened the door to related records. Judges usually limit the follow-on discovery to what you testified about, but privilege claims over that same condition become much harder to sustain once you’ve put it on the record yourself.
Fighting a Demand for Your Records
When someone tries to force disclosure, the usual first step is objecting to the discovery demand and making the requesting party file a motion to compel, at which point a judge decides whether the records are discoverable.
You can also seek a protective order under Code of Civil Procedure 2031.060, asking the court to limit or block disclosure.19California Legislative Information. California Code of Civil Procedure 2031.060 – Protective Order You need to show good cause, meaning unwarranted harm, embarrassment, or burden without restrictions. Courts can craft narrow orders allowing records to go to counsel but stay out of the public record, or limiting disclosure to specific categories of treatment. In close cases, a judge may conduct an in camera review, examining records privately before anyone else sees them, to decide what is genuinely relevant.
If a provider releases privileged records without proper authorization, you may have a separate claim under California’s Confidentiality of Medical Information Act for nominal and actual damages.20California Legislative Information. California Civil Code 56.36 – Violations Courts can also sanction parties who improperly obtain or use privileged information, including excluding the records from evidence. These remedies work only if you assert the privilege promptly. Objections raised for the first time on appeal, after records have already been admitted at trial, rarely succeed.
HIPAA and the CMIA Are Not the Same Thing
Doctor-patient privilege is an evidence rule about what can be used in court. HIPAA and California’s Confidentiality of Medical Information Act are privacy regimes about how providers and insurers handle your information day to day. They can apply even when the privilege doesn’t, and they impose their own procedural steps before a provider turns records over in response to a subpoena. If you’re trying to understand whether something can be used against you in a case, the evidence privilege is the right lens; if you’re trying to understand how your records get handled outside court, those other frameworks are where to look.
