If you suffered a traumatic brain injury (TBI) at work in California, workers’ compensation must provide the treatment reasonably required to cure or relieve its effects, and for many workers that includes a neurologist, neuropsychological testing and cognitive rehabilitation. Your treating doctor requests that care, the insurer reviews it against the state’s treatment guidelines, and you can challenge a denial through independent medical review. Knowing how referrals, medical provider networks and deadlines work can keep your care from stalling.
Key takeaways
- California’s treatment rules include a dedicated Traumatic Brain Injury Guideline that applies when the insurer reviews requests for neurological care.
- If your employer uses a medical provider network (MPN), an initial specialist appointment must be available within 20 business days of your request, and you may go outside the network if the MPN can’t deliver.
- If utilization review denies a neurology referral or testing, you generally have 30 days to request independent medical review (IMR).
- Depression, anxiety and mood changes after a brain injury can be treated in the claim, and a severe head injury is one of the exceptions that lets a psychiatric condition add to your permanent disability rating.
What neurological care for a TBI can include
Depending on the injury, a treating doctor may request:
- Consultation and follow-up with a neurologist
- Brain imaging such as CT or MRI
- Neuropsychological testing to measure memory, attention, processing speed and executive function
- Cognitive rehabilitation, speech therapy and occupational therapy
- Vestibular therapy for dizziness and balance problems
- Medication management for headaches, sleep problems and mood symptoms
- Psychiatric or psychological care for depression, anxiety or post-traumatic stress
The legal standard is the same for all of it: under Labor Code §4600, your employer must provide treatment that is reasonably required to cure or relieve the effects of the work injury. For an overview of all the benefits in a brain injury case, see workers’ comp for traumatic brain injuries.
How neurological treatment gets approved
- Your primary treating physician refers you. The doctor managing your care decides you need a specialist and submits a request for authorization (RFA) with supporting records.
- The insurer runs utilization review (UR). Routine decisions are generally due within five business days and no more than 14 days from the request; urgent requests within 72 hours (Labor Code §4610).
- The guidelines apply. The Medical Treatment Utilization Schedule (MTUS) includes a Traumatic Brain Injury Guideline in the Title 8 MTUS regulations. Under Labor Code §4604.5, the MTUS is presumed correct, but your doctor can rebut it with scientific medical evidence.
- If UR says no, request IMR. You generally have 30 days after the UR decision is served to ask for independent medical review (Labor Code §4610.5). The UR letter states the deadline and includes the form. See what IMR is and how it works.
While your claim is still being decided, your employer must authorize up to $10,000 in treatment, so you don’t have to wait for acceptance to start care.
Getting a neurologist inside a medical provider network
Most California employers use an MPN, which means your doctors generally come from the network’s list. The network must meet state access standards (8 CCR §9767.5):
| Rule | What it means for TBI care |
|---|---|
| Specialists within 60 minutes or 30 miles | The MPN should have neurologists and other specialists who treat common injuries reasonably close to your home or work. |
| Initial specialist appointment within 20 business days | Measured from your reasonable request through the MPN’s medical access assistant. |
| Can’t schedule within 10 business days | If the medical access assistant can’t get you a timely appointment, the employer must allow treatment with an appropriate specialist outside the MPN. |
| Specialist type not in the MPN | If your doctor refers you to a kind of specialist the MPN doesn’t include, you may choose one outside the network. |
After your first visit you can change treating doctors within the MPN, and you can ask for a second and third opinion if you disagree with a diagnosis or treatment plan (Labor Code §4616.3). If the dispute continues, an MPN independent medical review is available. Here is how to change your doctor in the MPN.
If your employer has no valid MPN, you may switch to a doctor of your choice 30 days after reporting the injury (Labor Code §4600(c)).
Why TBI treatment gets delayed or denied
- “The scans are normal.” Normal imaging doesn’t necessarily rule out a brain injury. Doctors also rely on the history of the accident, clinical exams and neuropsychological testing, so make sure those are documented.
- “The symptoms are subjective.” Memory lapses, headaches and light sensitivity are hard to see. A symptom journal and statements from family or coworkers who noticed changes can support what you report.
- “It’s psychological, not neurological.” Both can be part of the same work injury. Psychiatric treatment caused by a physical injury is generally covered.
- “General care is enough.” A general occupational clinic may not be equipped to assess cognitive deficits. Ask your treating doctor to explain in writing why a specialist is needed.
- “It’s pre-existing.” A prior concussion doesn’t bar a new claim if work caused or aggravated your condition, though it may affect apportionment of permanent disability (Labor Code §4663).
For the other disputes that come up in brain injury claims, see common workers’ comp issues in TBI cases.
A hypothetical example
Ana, a warehouse picker, is struck on the head by a box falling from a high shelf. The urgent care clinic in the MPN diagnoses a concussion, and her CT scan is normal. Weeks later she still has headaches, loses her train of thought and can’t tolerate the noise of the warehouse floor. Her treating doctor requests a neurology consult and neuropsychological testing. The MPN’s medical access assistant can’t find a neurologist with an opening within 10 business days, so under the access rules Ana may see an appropriate specialist outside the network. If UR later denies the testing, Ana can request IMR within 30 days.
Why the right care matters for your benefits
Thorough neurological records do more than guide treatment. They shape your work restrictions, your temporary disability, the eventual permanent disability rating and future medical care. For injuries on or after January 1, 2013, a psychiatric condition caused by a physical injury generally doesn’t increase your permanent disability rating, but a catastrophic injury, including a severe head injury, is an exception (Labor Code §4660.1(c)). And under Labor Code §4662, an injury to the brain resulting in permanent mental incapacity is conclusively presumed to be a permanent total disability.
If you disagree with your treating doctor about diagnosis, work status or permanent impairment, you can object and go to a qualified medical evaluator (QME). Treatment denials go through UR and IMR instead. See how IMR and QME differ.
Steps to protect your neurological care
- Report the injury in writing and file a DWC-1 claim form; your employer must give you one within one working day after learning of the injury.
- Tell every provider about the blow to the head, loss of consciousness, confusion or memory gaps, even if they seemed minor.
- Keep a daily symptom journal, and ask a family member to note changes in mood, memory or behavior.
- Ask your treating doctor to request a neurology referral and testing in writing, and get copies of the RFA and any UR decision.
- Calendar the 30-day IMR deadline the day a denial arrives.
- Keep track of mileage to appointments; medical travel is reimbursed at 76 cents a mile for travel on or after July 1, 2026.
Frequently asked questions
Can I see a neurologist outside my employer’s MPN?
Sometimes. If the MPN can’t schedule a specialist appointment within the required time, doesn’t include the type of specialist you were referred to, or isn’t validly set up, you may be able to treat outside it. Otherwise, you generally choose from the network’s doctors.
Does workers’ comp pay for neuropsychological testing?
It can, when it’s reasonably required to diagnose or treat the work injury. The request goes through utilization review using the MTUS, and a denial can be challenged through IMR.
My CT scan was normal. Can I still have a work-related brain injury?
Yes. Normal imaging doesn’t necessarily rule out a TBI, and doctors look at your history, exams and testing as well. Make sure your symptoms are recorded at every visit.
Is therapy for depression after a head injury covered?
Generally yes. Psychiatric or psychological treatment for a condition caused by a work injury is part of medical treatment, even when it can’t raise your rating.
What if the insurer ignores my doctor’s referral?
UR decisions have deadlines. If no timely decision is made, or the insurer delays without a reasonable basis, a lawyer can raise the issue with the Workers’ Compensation Appeals Board.
