The short answer is: all medically necessary care. California law places the obligation to provide treatment on the employer, not on the worker's private health insurance. Under Labor Code 4600, the employer must pay for everything reasonably required to cure or relieve the effects of the work injury.
The practical question is almost never what is covered in theory. It is whether Utilization Review will authorize the specific treatment your doctor ordered. Most routine care clears UR without a problem. Complex care like spine surgery and long-term pain management faces heavier scrutiny.
Below: every category of covered treatment. The 24-visit cap for chiropractic and physical therapy. How UR governs authorization. How future medical coverage works after settlement.
What categories of treatment does California workers' comp cover?
California workers' comp covers all care needed to cure or relieve a work injury. That includes doctor visits, surgery, physical therapy, drugs, and medical devices.
Labor Code 4600 puts the cost on the employer. The employer must pay for all care that is needed to treat the work injury. Coverage is broad. It includes the following:
- Doctor visits, specialist care, and surgery.
- Hospital stays and emergency care.
- Physical therapy and rehab.
- Chiro care (subject to a visit cap).
- Acupuncture (subject to a visit cap).
- Prescription drugs.
- Medical devices like braces, crutches, and wheelchairs.
- Home nursing care when the doctor orders it.
- Mental health care for work-related psychiatric injuries.
- Dental care caused by a work accident.
- Prosthetics and orthotics.
Coverage is not limited by the type of treatment. It is limited by medical need under the MTUS.
What is the 24-visit cap on chiro and physical therapy?
Labor Code 4604.5 caps chiro, PT, and acupuncture at 24 visits each per work injury. Post-surgical PT does not count against the cap.
The 24-visit cap was set in the 2004 reforms. It applies to chiro, PT, and acupuncture. Each category gets 24 visits per injury. The cap is not per year. It is per industrial injury. When a worker hits the cap, the carrier stops paying for that type of care.
Two paths can extend care past the cap. One is when the MPN does not have a qualified provider. The other is post-surgical rehab after a surgery approved through the MPN. Post-surgical PT does not count toward the 24-visit limit.
Treating doctors sometimes miss the cap issue. They keep ordering care until the carrier cuts it off. Workers benefit from knowing the cap limit early so they can plan their care accordingly.
Does workers' comp cover prescription drugs and medical devices?
Prescription drugs are covered through the carrier's pharmacy program. Medical devices like braces and crutches are covered when the doctor orders them.
The carrier pays for drugs through a pharmacy program. Generic drugs are the default. Brand-name drugs need extra medical justification. Some drugs face extra scrutiny under the MTUS. Disputes over drug approvals go through UR-IMR just like surgery disputes.
Medical devices are covered when the treating doctor orders them. That includes braces, crutches, and TENS units. For costly devices, the carrier will usually require an RFA with detailed clinical support. A prescription alone may not be enough for high-cost items.
What happens to medical coverage after settlement?
A Stipulated Award keeps future medical care open. A Compromise and Release (C&R) closes future care in exchange for a lump sum.
Cases settle two ways. A Stipulated Award keeps future care open for the accepted body parts. The carrier must pay for all future needed treatment with no time limit. UR-IMR still governs each new request. Workers with long-term care needs often prefer a Stip.
A C&R closes all claims for a lump sum. Once the WCAB approves it, the carrier owes no more medical care. Workers with permanent conditions should think carefully before closing future care. The cost of future treatment should be part of the settlement analysis.

Tap to call →How Yazdchi Law Fights for Treatment Authorization
California workers often receive less treatment than the law provides. The reason is usually not the law. It is that no one is pushing the carrier to comply.
The UR-IMR system is built to manage costs, not to maximize care. Workers who navigate it without help often accept treatment denials that a well-organized IMR packet would have overturned. Yazdchi Law helps treating physicians build strong RFAs. It files IMR applications on time. It pursues delay penalties when carriers act without reason.

Frequently Asked Questions
Does workers' comp cover surgery?
Yes. Surgery that is medically necessary to cure or relieve the effects of a work injury is covered under Labor Code 4600. Covered surgeries include orthopedic procedures, spinal surgery, abdominal repair, and any other procedure a treating physician documents as required for the industrial injury. The surgery must be authorized through the UR process before it can happen except in emergencies. Emergency surgery for a work injury is covered without prior authorization. The carrier pays the surgeon, hospital, and anesthesiologist directly. Most covered surgeries go through the RFA-UR process before being performed. Emergency surgery for a work injury is the main exception. The carrier pays the surgical providers directly at the workers' comp fee schedule rate.
Does workers' comp cover mental health treatment?
Yes, when the psychiatric condition is accepted as part of the claim. California workers' comp covers psychiatric treatment for cumulative stress injuries, PTSD from a workplace event, and psychological overlay from a physical injury. The same medical authorization rules apply. The treating physician, typically a psychiatrist, submits RFAs for medication, therapy, or inpatient care. UR applies MTUS psychiatric guidelines. IMR is available if UR denies. Psychiatric injuries have their own statute of limitations and reporting rules, so consulting an attorney early is important. The psychiatric injury claim has its own statute of limitations and requires a different reporting process than a physical injury claim. Consult an attorney early if the work situation produced a psychiatric condition, even if a physical injury is also present.
Does workers' comp pay for travel to medical appointments?
Yes. Labor Code 4600 includes mileage reimbursement to and from workers' comp medical appointments. The reimbursement rate is set by the state and updated periodically. Submit a mileage log with appointment dates and round-trip distances on the carrier's reimbursement form. Most carriers require submission within 90 days. Parking fees and some other travel costs are also reimbursable with receipts. For workers with long commutes to specialty care, cumulative mileage reimbursement across a long claim adds up significantly. Mileage reimbursement accumulates quickly on a long claim with frequent specialist appointments. Keep a running log from the start. Trying to reconstruct months of appointments from memory later is difficult and often incomplete. Ask about this early. Many workers do not know mileage is reimbursable until months into the claim.
What if the carrier refuses to authorize medically necessary treatment?
File for Independent Medical Review within 30 days of the UR denial. IMR is a records-based review by an independent physician who applies MTUS standards independent of the carrier. If IMR overturns the denial, the carrier must authorize the treatment. If IMR upholds the denial, the treating physician can submit a new RFA with stronger documentation. If the carrier is untimely in its UR decision, the WCAB can enforce compliance and impose delay penalties. Refusing to authorize medically necessary treatment without going through the UR-IMR process is also subject to WCAB remedy. A WCAB petition to compel treatment authorization is available when the carrier has refused to authorize without going through the required UR process. The WCAB can order the carrier to comply and assess penalties for unreasonable refusal.
Can the carrier stop my medical care?
Not unilaterally. The employer's obligation to provide treatment under Labor Code 4600 continues as long as the claim is open and treatment is reasonable and necessary. The carrier can dispute individual treatment requests through UR-IMR, but it cannot close the medical obligation without either a Compromise and Release settlement that closes all claims or a WCAB order. A treating physician who issues a Permanent and Stationary report does not close medical care. It just shifts from active treatment to maintenance care when applicable. A treating physician who reaches Permanent and Stationary status and writes a report indicating no future medical care is needed does not close the carrier's obligation. Only a WCAB order or a settlement approved by the WCAB closes the medical obligation.
Does workers' comp cover a second opinion before surgery?
Yes. Workers can request a second opinion within the Medical Provider Network or request a panel Qualified Medical Evaluator under Labor Code 4062 when a medical dispute arises. For surgical disputes, a QME whose report supports the surgery can unlock authorization the MPN treating physician was reluctant to pursue. Second opinions are particularly useful for spinal surgery, where conservative-care timelines and the standard for surgical candidacy vary among physicians. An attorney can help structure the second opinion to maximize its impact on the authorization dispute. A QME can address both surgical candidacy and treatment authorization when the dispute involves medical necessity. QME reports favoring surgery or specific treatment carry significant weight in both UR-IMR and WCAB proceedings. Workers who do not know their rights often accept denials without challenging them. An attorney reviews each denial, checks whether the RFA met MTUS criteria, and files the IMR packet when the record supports it. That review often changes the outcome. That record protects every future request.
