CRPS and Chronic Pain After a Work Injury: California Workers' Comp

Is CRPS or chronic pain covered by workers' comp in California?

Yes, if a work injury caused it or made it worse. California's no-fault rule covers any injury or disease tied to your job, not just one sudden accident.

Complex regional pain syndrome, or CRPS, usually follows an injury to an arm or leg. It causes pain that is far stronger and longer lasting than the original injury would explain. The National Institute of Neurological Disorders and Stroke describes two types. Type 1 follows an injury with no clear nerve damage. Type 2 follows direct damage to a specific nerve. Doctors also call this condition RSD, short for reflex sympathetic dystrophy. Pain that does not fit either type, including fibromyalgia, can also qualify.

Under Labor Code 3600, your employer answers for a work injury without regard to fault. The injury must arise out of your job and happen during your work. Labor Code 3208 says a covered injury includes any disease tied to your job, not just a sudden event. CRPS and ongoing pain conditions usually follow an earlier event. They rarely show up on their own.

Coverage is the easy part on paper. The hard part is proving your pain is tied to your job. The next section covers that proof.

How do you prove CRPS or ongoing pain came from your job?

You need a clear medical opinion that ties your pain to a specific work injury or to repeated strain at work, since neither CRPS nor fibromyalgia shows up on a standard test.

Neither condition has one lab test that proves it. NINDS says doctors diagnose CRPS mainly from symptoms and a physical exam. Nerve tests can sometimes confirm Type 2, where a specific nerve was hurt. They usually cannot confirm Type 1, the more common form. A normal test result does not mean you do not have CRPS.

Insurers know this. They often push back before accepting these claims. When the insurer will not agree with your treating doctor, a panel process assigns a Qualified Medical Evaluator, or QME, to examine you, whether or not you have an attorney. If you have an attorney, both sides can agree on one doctor instead, called an Agreed Medical Evaluator, or AME, a path not open to unrepresented workers. Our page comparing a QME and an AME explains both paths.

Save anything that ties your pain back to the original work event: the first incident report, early medical notes, and later notes where a doctor links your ongoing pain to that event. If you had similar pain before you were hurt at work, the insurer may raise apportionment. Labor Code 4663 requires the evaluating doctor to state what share of your disability came from the work injury and what share came from something else. The doctor must give real medical reasons for that split. Our guide to apportionment explains how that works.

Will workers' comp pay for a spinal cord stimulator or other pain treatment?

The same way it pays for any other care. Your doctor requests it, a reviewer checks it against medical guidelines, and you can appeal a denial.

Under Labor Code 4600, your employer must provide medical care that is reasonably needed to cure or relieve your injury. That care usually comes through a medical provider network, or MPN, unless you properly predesignated your own doctor first. Your treating doctor, called the PTP, sends a request for authorization for each treatment.

That request goes through utilization review, or UR, under Labor Code 4610. A reviewer checks the request against state treatment guidelines. The reviewer can approve, change, or deny it based on medical need. If UR denies or changes a request, you can ask for independent medical review, or IMR, under Labor Code 4610.5. You generally have 30 days from the denial notice to ask. Our guide to utilization review covers that appeal step by step.

A spinal cord stimulator is a device some doctors use for CRPS that has not improved with other care. NINDS describes it as a device that sends mild electrical signals near the spinal cord. This can change how pain reaches the brain and can ease pain in some people with CRPS. A stimulator goes through UR just like any other treatment. Approval depends on your records and the guidelines, not the name of the device.

Step	What happens	Your deadline
Treatment request	Your doctor asks the insurer to approve care	None
Utilization Review	A reviewer approves, modifies, or denies it	Days
Denied	You request Independent Medical Review	30 days to appeal
IMR decision	A neutral doctor decides on the records	Final and binding

How long can you receive temporary disability for CRPS or long-term pain?

The same 104-week limit that applies to most injuries. CRPS, fibromyalgia, and most chronic pain are not on the law's short list of conditions that get more time.

Labor Code 4656 caps temporary disability at 104 weeks within five years of your injury for most claims. The law stretches that to 240 weeks for a short list of physical conditions:

• Acute and chronic hepatitis B or C
• Amputations
• Severe burns
• HIV
• High-velocity eye injuries and chemical burns to the eyes
• Pulmonary fibrosis and chronic lung disease

A long-running pain condition is not on that list. The standard 104-week cap applies even when treatment runs on for years. Under Labor Code 4650, your first disability check is due within 14 days after your employer learns of your injury and disability. Later checks follow every two weeks.

Can chronic pain raise your permanent disability rating?

Yes. Lasting pain and lost function are part of what a doctor measures. But the law does not add one extra number just for having long-term pain.

For injuries on or after January 1, 2013, Labor Code 4660.1 sets the rating formula. A doctor measures your whole person impairment under the American Medical Association's Guides, Fifth Edition. The doctor then multiplies that number by 1.4. Your age and job at the time of injury adjust the result further. An older formula covers injuries from 2005 through 2012. Our guide to permanent disability ratings walks through that math, and the Labor Code 4660.1 statute card covers the formula itself.

One limit matters a lot in a pain case. The same law blocks an added rating for sleep problems, sexual dysfunction, or a psychiatric disorder caused by a physical injury. There are narrow exceptions for a violent act or a catastrophic injury, such as paralysis, loss of a limb, a severe burn, or a severe head injury. CRPS and ongoing pain often bring insomnia, anxiety, or depression. These effects can still be treated, but they usually do not add a separate percent to your rating. Our guide to psychiatric injury claims covers when a psychiatric injury is rated on its own. This page does not use or quote any AMA Guides percentage, since the right number depends on your own exam.

What is a CRPS settlement worth?

There is no official average. Your settlement follows your rating, your wage, any apportionment, and your future medical needs, not the name of your condition.

California workers' comp does not pay pain and suffering the way some lawsuits do. Our guide to pain and suffering and workers' comp explains that difference. It pays a set of fixed benefits built around your permanent disability rating instead.

PD rating	Benefit weeks	Award at the 2026 max ($290/wk)
10 percent	30 weeks	$8,700
20 percent	75 weeks	$21,750
30 percent	130 weeks	$37,700
40 percent	200 weeks	$58,000
50 percent	270 weeks	$78,300
60 percent	350 weeks	$101,500
70 percent	430 weeks	$124,700 plus a life pension

Four things move that number here. Your rating, set by the exam above. Your average weekly wage at the time of injury. Any apportionment, since a past injury can shrink the share your employer owes. And your future medical needs, since ongoing pain care can be worth protecting with an award that keeps your medical care open. A number you see online cannot know any of these facts in your own claim.

What about fibromyalgia claims in California workers' comp?

Fibromyalgia can be a covered claim. But insurers often fight it harder than a typical injury, since doctors still do not fully know what causes it.

The National Institute of Arthritis and Musculoskeletal and Skin Diseases describes fibromyalgia as a long-lasting disorder. It causes widespread pain, tenderness, and fatigue. Its cause is not fully known, though people with it seem to feel pain more easily. Other painful or mood conditions can trigger it. Since there is no single test, insurers often question whether work caused it at all.

The legal standard does not change just because the diagnosis is harder to pin down. The no-fault rule under Labor Code 3600 still applies. A treatment request still goes through the same review and appeal steps covered above. What usually changes is how much medical proof you need. A doctor who can link your symptoms to a specific work event, or to repeated strain on the job, gives your claim a stronger base than the diagnosis alone.

When does a lawyer help with a CRPS or chronic pain claim?

Most often when the insurer disputes that your condition is work related, denies care, or when it is time to rate and settle your case.

A lawyer tends to help most at a few points: when the insurer denies your claim and you need to fight that decision, when UR denies care your doctor wants while the appeal clock runs, when apportionment is raised against you, and when you must decide how to settle. If your claim was denied outright, our guide to a denied workers' comp claim covers next steps. If you are weighing a lump sum against an award that keeps your medical care open, our comparison of a Compromise and Release and a Stipulated Award explains the difference.
