Under informed consent law in California, your healthcare provider must explain your condition, the treatment they’re recommending, its risks, the alternatives, and what happens if you refuse, all before you agree to anything. The test is patient-centered: they owe you the information a reasonable person in your situation would want in order to decide.1Legal Information Institute. Cal. Code Regs. Tit. 22, 72528 – Informed Consent Requirements On top of that, a provider must share the specialized details a competent practitioner in the same field would raise under similar circumstances.2Justia Law. Cobbs v. Grant Risks that are commonly known and obvious don’t have to be spelled out.
What Your Provider Has to Tell You
No single statute lists a universal script, but regulations and case law require several core categories of information before you agree to treatment:
- Your diagnosis and why an intervention is being recommended.
- What the proposed treatment involves, how it works, and its expected benefits.
- Known risks and complications that could materially affect your decision.
- Available alternatives and their own risks and benefits.
- What could happen if you decline the treatment entirely.
The provider actually performing or ordering the procedure is the one responsible for having this conversation with you. A hospital cannot discharge the duty by handing you paperwork at admission. The licensed practitioner who will carry out the procedure has to make sure you understand.1Legal Information Institute. Cal. Code Regs. Tit. 22, 72528 – Informed Consent Requirements
When You Have to Sign Something
California generally requires a signed written consent form confirming that your provider gave you a verbal explanation and that you understand your right to accept or refuse treatment. That signed form goes into your medical record.3Legal Information Institute. Cal. Code Regs. Tit. 9, 784.29 – Informed Consent to Medical Treatment The general consent form you sign at admission typically covers only routine nursing care and emergency treatment, not the specific procedures that come later.
Some procedures carry heavier documentation requirements. A hysterectomy, for instance, requires both verbal and written informed consent with specific disclosures: that you may withdraw consent at any time without losing benefits or future care, that the procedure is irreversible and will cause infertility, a description of the surgical approach and alternatives, and an explanation of the risks including anesthesia effects.4California Legislative Information. California Health and Safety Code 1690
Who Can Give Consent
Adults and Surrogates
You can consent to your own treatment if you’re 18 or older and mentally capable of understanding the information your provider gives you. Capable means you can grasp the nature of the proposed treatment, weigh the risks and alternatives, and communicate a decision. Age alone isn’t enough if unconsciousness, cognitive impairment, or another condition prevents real understanding.
When an adult patient lacks capacity, a surrogate steps in. California law sets a priority order: first, an agent you previously named in an advance health care directive; next, a court-appointed conservator with healthcare authority; and then family members in a defined order. The surrogate is supposed to make the decision you would have made, not the one they’d prefer.
Minors Who Can Consent Without a Parent
Minors generally can’t consent to their own care, but California carves out several exceptions:
- A minor at least 15, living apart from parents or guardian (regardless of whether the parents approved the arrangement or how long it has lasted), and managing their own finances may consent to medical, dental, and vision care.5California Legislative Information. California Family Code 6922
- A minor of any age may consent to treatment related to preventing or treating pregnancy.
- A minor 12 or older who may have been exposed to a reportable infectious or communicable disease can consent to diagnosis and treatment for that condition.
- A minor 12 or older can consent to outpatient mental health counseling, but only if the treating professional believes the minor is mature enough to participate meaningfully in treatment.
The maturity requirement for mental health care gives the clinician real discretion. A 12-year-old who wants therapy doesn’t automatically qualify; the clinician has to make an independent judgment about the minor’s capacity to engage in the process.
Telehealth and Language Access
When care happens through telehealth, there’s an extra consent step. Before the visit begins, your provider must tell you telehealth will be used and get your verbal or written agreement, and that agreement has to be documented in your record.6California Board of Psychology. Standards of Practice for Telehealth Regulation Advisory This is separate from the regular informed consent for the treatment that follows. Your provider should also cover the risks specific to remote care: confidentiality and data security concerns, the chance of a dropped connection or technology failure, any meaningful differences from an in-person visit, and insurance coverage limitations.
Consent is meaningless if you can’t understand what you’re being told. California regulations require healthcare facilities to arrange an interpreter when a patient or their representative can’t communicate with the treating practitioner because of a language barrier or deafness.7Legal Information Institute. Cal. Code Regs. Tit. 22, 73524 – Informed Consent Requirements The interpreter must be fluent in both English and the patient’s language, or capable of communicating with a deaf patient. Formal certification isn’t required, but fluency is. State-funded facilities that serve significant non-English-speaking populations face additional obligations under the Dymally-Alatorre Bilingual Services Act, including translated written materials or translation assistance for English-language forms.
When a Provider Can Treat You Without Consent
California recognizes a small number of situations where the full informed consent process can be bypassed. These exceptions are narrow, and a provider who relies on one has to justify it.
Medical Emergencies
The most common exception applies when an unanticipated condition requires immediate action to save your life, prevent serious bodily harm, or relieve severe physical pain, and it’s impractical to get consent from you or a surrogate. The provider has to document the emergency in your record, and whatever treatment they give must be what a competent practitioner would do in similar circumstances.8California Department of Public Health. Frequently Asked Questions – Informed Consent The exception covers only what’s necessary to address the immediate threat, not unlimited treatment authority.
Therapeutic Privilege
A provider may withhold specific information if they genuinely believe disclosure would cause you such severe psychological distress that it would compromise your physical health or your ability to make a rational decision. Courts treat this “therapeutic privilege” with considerable skepticism. The burden falls squarely on the provider, and it can’t be used just because a doctor thinks bad news would upset you. The harm from disclosure has to be serious enough to be medically counterproductive.
Patient Waiver
You can voluntarily waive your right to receive detailed information. Some patients genuinely prefer not to hear every risk and ask their provider to decide on their behalf. The waiver has to be your own free choice, not something your provider suggested to save time. Even with a waiver, the provider should document that you were offered the information and chose to decline it.
What to Do If Your Provider Didn’t Get Consent
Negligence Versus Battery
The legal category matters more than most patients realize. If your provider gave you some information but failed to disclose a material risk, and you were harmed by that undisclosed risk, the claim is medical negligence. You’d need to prove that a reasonable person given the missing information would have refused the treatment. These claims fall under California’s Medical Injury Compensation Reform Act (MICRA), which caps noneconomic damages. For 2026, the cap in a non-fatal case is $470,000, and in a wrongful death case, $650,000. Both caps increase annually until reaching $750,000 and $1,000,000 respectively in 2033.
If your provider performed a procedure you never agreed to at all, or performed something substantially different from what you consented to, the claim is medical battery. Battery claims don’t require you to prove that a different disclosure would have changed your mind, and they fall outside the MICRA caps, so there is no statutory ceiling on noneconomic damages. That’s why providers and their insurers push hard to frame consent disputes as negligence rather than battery.
Filing Deadlines
For professional negligence claims, you have to file within one year of discovering the injury, or within three years of the date the injury occurred, whichever comes first.9California Legislative Information. California Code of Civil Procedure 340.5 The three-year outer limit can be extended only for fraud, intentional concealment, or a foreign object left in your body. For minors, the deadline is three years from the alleged wrongful act, except that children under six have until their eighth birthday if that gives them a longer window.
Before filing suit, you must give the healthcare provider at least 90 days’ written notice of your intent to sue. If you serve that notice within 90 days of the statute of limitations expiring, the filing deadline is automatically extended by 90 days from the date you served the notice.10California Legislative Information. California Code of Civil Procedure 364 Missing the notice requirement or the filing deadline can end an otherwise valid claim, so these dates should be the first thing you pin down.
Reporting a Provider
You can also file a complaint with the Medical Board of California. Consent violations generally fall under unprofessional conduct. Penalties range from probation with mandatory education courses to full license revocation, depending on the severity and pattern of the violation.11Medical Board of California. Manual of Model Disciplinary Orders and Disciplinary Guidelines A provider placed on probation may face a practice suspension of 90 days or more as a condition of that probation. A board complaint is separate from any civil lawsuit and can be filed regardless of whether you also sue.
