California Emergency Room Laws: Your Rights, Billing, and Complaints

California emergency room laws require any hospital with an emergency department to screen you, stabilize any emergency condition, and treat you without first checking your insurance or ability to pay. Those duties come from the federal Emergency Medical Treatment and Labor Act (EMTALA) and California’s Health and Safety Code, and they are backed by additional state rules on language access, medical privacy, and hospital billing. Violations can cost a hospital up to $136,886 per incident and put its Medicare funding at risk.¹

What the Hospital Must Do When You Arrive

Every hospital that takes Medicare has to provide an appropriate medical screening examination to anyone who shows up at the emergency department, or has someone request care on their behalf. Private insurance, Medi-Cal, no coverage — it doesn’t matter.² California Health and Safety Code 1317 reinforces this, requiring emergency services for anyone in danger of losing life or suffering serious injury or illness.³

A physician or other qualified medical professional performs the screening. It can include a physical exam, imaging, blood work, and any other test the ER routinely runs. The hospital cannot pause the process to ask about payment, and California regulations require health plans to reimburse for these screening exams with no prior authorization.⁴

If the screening finds an emergency medical condition, the hospital must provide whatever treatment is needed to stabilize you before it discharges or transfers you. Stabilization means your condition is unlikely to get materially worse during that discharge or transfer. The treating physician decides when you’re stable. If the screening finds no emergency, the EMTALA obligation ends, and normal rules about prior authorization for non-emergency care apply.

Psychiatric Crises

EMTALA explicitly covers psychiatric disturbances and symptoms of substance abuse as emergency medical conditions when the symptoms are severe enough that delay could put someone’s health in serious jeopardy.⁵ A psychotic episode, a suicidal crisis, or acute withdrawal is entitled to the same screening and stabilization as a broken bone or chest pain. If the hospital lacks psychiatric capacity, it must arrange a transfer while continuing to treat the patient.

Active Labor

If a pregnant patient is in active labor and there isn’t enough time to safely transfer her, or the transfer itself could endanger mother or baby, the hospital must deliver the child and stabilize both patients. Insurance status cannot be a reason to send someone in active labor elsewhere.²

When a Hospital Can Transfer You

Both California law and EMTALA prohibit transferring an emergency patient for nonmedical reasons, such as avoiding the cost of treatment. That anti-dumping rule sits at the center of both laws.⁶ A transfer is only permitted when the medical benefits of moving you outweigh the risks, and several things must happen first.

A physician must certify in writing that the transfer is medically justified. If no physician is immediately available, another qualified medical professional can authorize it, but a physician must review and co-sign the certification afterward. The receiving hospital must agree to accept you and have the staff, beds, and equipment to provide the care you need. The transferring hospital must do whatever it can to minimize risks before you leave.²

Transportation has to fit the situation. A patient on a ventilator needs an ambulance with advanced life support, not a basic transport van. Your medical records, test results, and treatment notes must travel with you. Incomplete handoffs are one of the most common ways transfer violations happen. Hospitals with specialized capabilities, such as burn centers or Level I trauma centers, generally cannot refuse to accept a transfer if they have the capacity to treat you.

Your Right to Refuse Treatment

EMTALA protects your right to receive emergency care, but it doesn’t force you to accept it. You can refuse the screening, refuse stabilizing treatment, or refuse a transfer. The hospital must explain the risks and benefits and document your refusal in writing.²

Once you refuse care after being informed of the risks, the hospital has met its EMTALA obligation. That signed refusal is also the hospital’s primary defense if something goes wrong later, which matters more than most patients realize. If you’re incapacitated and cannot consent or refuse, the law presumes you would want emergency treatment. That implied consent has one hard limit: it cannot override a prior explicit refusal such as a valid do-not-resuscitate order.

Language Access

Every licensed acute care hospital in California must maintain a policy for helping patients who have limited English proficiency or other communication barriers. Under Health and Safety Code 1259, hospitals must make interpreters available on-site or by phone around the clock and file their updated language access policies with the state health department each year.⁷

Federal law adds Section 1557 of the Affordable Care Act, which treats language barriers as national-origin discrimination. Hospitals must offer qualified interpreters at no charge, meaning someone proficient in both languages, familiar with medical terminology, and bound by confidentiality. Hospitals cannot require you to bring your own interpreter or rely on minor children to translate, except in a genuine emergency when no qualified interpreter is immediately available.⁸ If machine translation is used for consent forms or discharge instructions, a qualified human translator must review the output.

Privacy and Mandatory Reporting

ERs handle sensitive information, and both federal and state law restrict who can see it. HIPAA sets the federal baseline, but California’s Confidentiality of Medical Information Act often goes further, and hospitals must follow whichever rule is stricter.⁹ In practice, a hospital cannot release your records without your consent except in narrow situations like court orders, public health emergencies, or law enforcement requests authorized by statute.

Some situations override privacy for public-safety reasons. California Penal Code 11160 requires any health practitioner who treats a patient with a gunshot wound or an injury that appears to result from assault or abuse to report it to local law enforcement immediately by phone, with a written report within two business days.¹⁰ Separate state laws require reporting suspected child abuse, elder abuse, and dependent adult abuse.

What the Hospital Can Charge You

Getting treated is one thing. Getting the bill is another. Several overlapping laws limit what an ER can charge, and knowing them can save you thousands of dollars.

Surprise Bills From Out-of-Network Providers

The federal No Surprises Act, in effect since 2022, prohibits out-of-network emergency providers from billing you for the difference between their charges and what your insurance pays. Your cost-sharing at an out-of-network ER must be calculated as if the provider were in-network, based on the lesser of the billed charge or the plan’s qualifying payment amount.¹¹ If the provider and insurer can’t agree on a payment amount, they take it to an independent arbitration process. You stay out of the middle.

Financial Assistance at Nonprofit Hospitals

Most California hospitals are nonprofit and have to maintain a written financial assistance policy under Internal Revenue Code Section 501(r). The policy must publish clear eligibility criteria for free or discounted care, explain how to apply, and describe how charges are calculated. It must cover all emergency and medically necessary care at the facility, and the hospital cannot reject an application for missing paperwork unless that specific documentation is described in the policy or the application form.¹²

California Fair Pricing

Under Health and Safety Code 127420, California hospitals must make reasonable efforts to determine whether any public or private coverage applies to your care. If you’re billed without having shown proof of coverage, the bill must include a notice explaining that you may qualify for Medi-Cal, Medicare, or other programs, and that financial assistance may be available.¹³ Don’t ignore that notice. Applying for financial assistance after an ER visit is one of the most effective ways to reduce or eliminate a hospital bill, and many people who qualify never apply.

Discharge Planning

Federal rules require hospitals to run a discharge planning process that identifies patients at risk of complications after leaving. The process has to figure out what follow-up you need, whether that means home health, outpatient referrals, or post-acute care, and whether those services are actually available to you.¹⁴ The plan has to be discussed with you or your representative and reflect your goals and preferences, and all necessary information has to be sent to whoever handles your follow-up.

Before you leave, ask the treating physician or nurse what symptoms should bring you back, when to follow up with your primary care doctor, and what medications you need. That is the point where preventable readmissions happen.

Penalties When Hospitals Break These Rules

Under EMTALA, the Office of Inspector General can impose civil fines on hospitals and individual physicians for each violation. After the most recent inflation adjustment in January 2026, a hospital with 100 or more beds faces up to $136,886 per violation. Hospitals with fewer than 100 beds face up to $68,445 per violation. The same $136,886 cap applies to individual physicians who negligently violate EMTALA.¹ Beyond fines, CMS can terminate a hospital’s Medicare provider agreement, and the OIG can exclude a physician from federal healthcare programs for gross, flagrant, or repeated violations.¹⁵

California adds its own layer. Health and Safety Code 1317.3 requires hospitals to adopt emergency care policies as a condition of licensure and gives patients a private right of action. If a hospital denies you emergency treatment or transfers you improperly, you can sue for damages and reasonable attorney’s fees.¹⁶ Privacy violations under the CMIA carry administrative fines and nominal damages payable to the affected patient, and knowing or willful violations carry substantially higher penalties.⁹

How to File a Complaint

If you believe a California hospital violated your emergency care rights, file an EMTALA complaint directly with CMS. Federal and state agencies work together to investigate. You can submit online, and CMS will confirm receipt by email if you provide your contact information.¹⁷ No lawyer, no fee.

For California-specific issues, including licensing and patient safety, the California Department of Public Health accepts reports through its Healthcare Facilities Complaint Intake. Privacy violations can also go to the U.S. Department of Health and Human Services Office for Civil Rights for HIPAA, or to the California Attorney General’s office for CMIA. Keep copies of medical records, bills, and written communications, and write down the dates and names of staff you interacted with while the details are fresh.
