Doctor Says Yes, Work Comp Says No: Treatment Denials for First Responders in LA

September 11, 2026

A treating physician may believe that an injured first responder needs surgery, physical therapy, medication, injections, diagnostic testing, or another form of care. However, that recommendation does not automatically mean workers’ compensation will approve it.

California allows claims administrators to review requested treatment for medical necessity through utilization review, or UR. For Los Angeles police officers, firefighters, sheriff’s personnel, and other public-safety employees, a denial can create more than a medical setback. A denial can prolong pain, extend work restrictions, and make a safe return to demanding duties more difficult. California provides a separate process for challenging treatment denials through Independent Medical Review, or IMR.

Knowing why treatment was denied, what evidence the reviewer considered, and how quickly you need to respond can make an important difference. Experienced workers’ comp lawyers in LA, CA can help identify the right next step when your doctor and the insurance carrier disagree about your care.

What can first responders in Los Angeles do when work comp denies medical treatment?

A first responder can generally challenge a medical-necessity treatment denial through California’s Independent Medical Review process. Before reaching IMR, however, it is important to understand what the utilization review decision actually says and whether workers’ comp denied the treatment entirely or only modified part of the request.

California requires claims administrators to use utilization review when deciding whether physician-recommended treatment is medically necessary. The review should rely on California’s applicable medical treatment guidelines, and a physician reviewer must make a decision that modifies or denies treatment.

What should a utilization review denial explain? 

A written UR denial should clearly explain why the requested treatment was denied or modified rather than simply saying it is “not medically necessary.”

It should identify:

• The treatment that was requested
• The medical records and information reviewed
• The clinical reasoning behind the decision
• The guideline or medical criteria used
• Any information the reviewer believed was missing
• Whether a new request may be submitted with additional documentation

Keep in mind that a denial based on missing records may require a different response than one based on a disagreement over whether the treatment meets California’s medical guidelines.

How does Independent Medical Review challenge a treatment denial?

IMR allows an independent physician to review whether disputed treatment is medically necessary after utilization review denies or modifies a treating doctor’s request. California uses IMR for these medical-treatment disputes rather than sending the medical-necessity question directly to a workers’ compensation judge.

The application should include the written UR decision, and the claims administrator is required to provide the appropriate IMR form with a denial or modification based on medical necessity.

How long does a first responder have to request IMR?

For most treatment disputes, California’s current IMR rules require the request to be filed within 30 days after service of the written UR determination. If the dispute involves only a drug listed on California’s MTUS Drug List, the deadline is generally 10 days. Missing the applicable filing period can affect the ability to obtain IMR, so the denial letter and its date should be reviewed promptly.

California also permits a voluntary internal UR appeal, but using that process does not eliminate the IMR filing deadline. A worker should therefore be careful not to let an internal appeal consume the time available to request independent review.

Expedited IMR may be available when waiting through the standard process could seriously threaten the worker’s health or recovery. The treating physician generally must document why faster review is medically necessary.

Why can treatment denials matter so much for first responders?

First responders often need to recover to a higher functional level before safely returning to duty. A shoulder, knee, back, cardiovascular, or psychological condition can affect emergency driving, lifting, climbing, physical restraint, weapons handling, or other essential tasks.

Delayed treatment can therefore prolong work restrictions and complicate return-to-duty decisions.

A UR denial may remain effective for 12 months for the same treatment recommended by the same physician, or another physician in that practice group, unless a new request documents a material change in the facts underlying the earlier decision.
