Hand and Wrist Injuries at Work: California Workers’ Comp Guide

Yes. Hand, wrist and finger injuries you suffer at work in California, from carpal tunnel syndrome to fractures to amputations, are generally covered by workers’ compensation. That includes all reasonable medical care, wage-replacement checks while you can’t work, and permanent disability payments if you are left with lasting loss of grip, motion or sensation.

Many workers search for a “workers’ comp payout for loss of a finger” and expect a fixed number. California doesn’t work that way. There is no price list per finger. What you receive depends on a medical rating of how much function you lost, which digit was affected, your occupation and your age, plus your wage-loss benefits and future medical care. Two workers who lose the same finger can end up with very different results.

This guide covers the most common hand and wrist injuries, how they are diagnosed and treated, how permanent disability is rated, the problems insurers raise, the deadlines, and when you may have a claim beyond workers’ comp.

Common hand and wrist injuries at work

Your hands do almost everything on the job, which is why they are injured so often. Common work injuries include:

• Carpal tunnel syndrome: compression of the median nerve at the wrist, often from repetitive gripping, typing, scanning or vibrating tools.
• Tendon conditions such as tendinitis, de Quervain’s tenosynovitis and trigger finger.
• Fractures of the wrist (distal radius or scaphoid), hand (metacarpals) or fingers, usually from falls or crush incidents.
• Lacerations that cut tendons or nerves, common in food processing, construction and manufacturing.
• Crush injuries and amputations from presses, conveyors, saws, doors and vehicle loading.
• Burns from heat or chemicals, and nerve damage that can lead to chronic pain conditions.

We see these injuries most often among warehouse workers, assembly line and food processing workers, cooks, mechanics, construction trades, cashiers, office and data-entry staff, and hairstylists. A sudden injury, such as a hand caught in a machine, is a specific injury. Carpal tunnel and tendinitis are usually cumulative trauma, and the date of injury is when you first had disability and knew or should have known that work caused it (Labor Code 5412).

Symptoms, diagnosis and testing

Some hand injuries are obvious. Others, especially repetitive-strain injuries, build slowly. See a doctor if you notice:

• Numbness or tingling in your thumb, index and middle fingers, often worse at night
• Weak grip or dropping objects
• Pain, swelling or clicking at the wrist or the base of the thumb
• A finger that locks or catches when you bend it
• Loss of feeling or color change after a cut or crush injury

Doctors use a physical exam and provocative tests, then imaging. X-rays show most fractures, though a scaphoid fracture can hide on early films and may need an MRI or CT scan. An MRI also shows ligament and tendon tears. For nerve symptoms, an EMG and nerve conduction study (EMG/NCS) confirms carpal tunnel or cubital tunnel syndrome and measures severity. If numbness runs up the arm, the problem may start in the neck instead; see our guide to neck and cervical spine injuries at work.

Watch: injured at work in California

Our attorneys explain what your employer must do after a work injury, and what to do in the first 24 hours to protect your claim.

Treatment, surgery and getting care approved

The insurer must pay for all reasonable and necessary treatment for your work injury (Labor Code 4600). For hand and wrist injuries that can include splinting, occupational and hand therapy, injections, carpal tunnel release, open reduction and internal fixation of fractures, tendon and nerve repair, replantation, and prosthetics after an amputation.

Treatment usually goes through your employer’s Medical Provider Network (MPN), and after the first visit you can generally choose a hand specialist within the network. Requests go through utilization review (UR). If surgery or therapy is denied, you can ask for Independent Medical Review (IMR), generally within 35 days of service of the UR decision (Labor Code 4610.5). Occupational and physical therapy are generally capped at 24 visits per injury unless the insurer authorizes more (Labor Code 4604.5), so ask your doctor to document why additional therapy is needed. Read more about your medical treatment rights in California.

While you recover, you are entitled to temporary disability at two-thirds of your average weekly wage, subject to state limits (for 2026, a maximum of $1,764.11 per week). It is generally limited to 104 weeks within five years, but for amputations and certain other serious injuries it can run up to 240 weeks (Labor Code 4656).

What a hand injury or lost finger may be worth

Once your condition stops improving, a doctor rates your permanent impairment using the AMA Guides, Fifth Edition. For the upper extremity, the doctor measures loss of motion, strength, sensation and any amputation for each digit, then converts it step by step: finger to hand, hand to arm, arm to whole person. The thumb carries far more weight than the little finger, and losing a finger at the base rates higher than losing a fingertip.

That impairment is then adjusted for your occupation and age under the state rating schedule and converted into weeks of payments (Labor Code 4658, 4660). The result is your permanent disability rating. Your benefits can also include future medical care, the supplemental job displacement voucher, and sometimes added ratings for pain or for loss of grip that affects other activities.

Benefit	What it pays for	Rule
Medical care	Surgery, therapy, prosthetics, medication, mileage	Labor Code 4600
Temporary disability	Lost wages during recovery	Labor Code 4653, 4656
Permanent disability	Lasting loss of hand or finger function	Labor Code 4658, 4660
Job displacement voucher	Retraining if your employer can’t offer suitable work	Labor Code 4658.7
Future medical	Ongoing care after the case ends	Part of an award or settlement

💡 Example: Carlos, a line worker, receives a 12% permanent disability rating after a partial finger amputation. Under Labor Code 4658, the first 9.75% is paid at 3 weeks per percent (29.25 weeks) and the remaining 2.25% at 4 weeks per percent (9 weeks), for a total of 38.25 weeks of payments at his weekly PD rate. This example is hypothetical.

Common claim problems and insurer defenses

• “It’s not from work.” Insurers often blame carpal tunnel on age, weight, diabetes or hobbies. Work only needs to be a contributing cause for the injury to be covered.
• Apportionment. Permanent disability may be reduced for non-work causes only when a doctor gives a reasoned explanation (Labor Code 4663), and prior awards for the same body part may be subtracted (Labor Code 4664).
• Late reporting. Repetitive injuries creep up, and workers wait. Notice is due within 30 days of knowing the injury is work-related (Labor Code 5400).
• Low ratings. A rating that ignores grip loss, sensory loss or a second injured digit leaves money on the table. If you disagree with the rating, a Qualified Medical Evaluator or Agreed Medical Evaluator can evaluate you.
• Light duty that doesn’t fit. Being sent back to tasks that violate your restrictions can worsen the injury. Ask for your restrictions in writing.

If the insurer has denied your claim outright, see our guide to a denied workers’ compensation claim.

Machine injuries: when you can sue beyond workers’ comp

Workers’ comp is usually your only remedy against your employer (Labor Code 3602). Serious hand injuries are a major exception area:

• Power press guards. If your employer knowingly removed, or knowingly failed to install, a point-of-operation guard on a power press that the manufacturer required, you may sue the employer directly (Labor Code 4558).
• Serious and willful misconduct. If the injury resulted from the employer’s serious and willful misconduct, such as knowingly ignoring a dangerous safety violation, your compensation can be increased by one-half (Labor Code 4553).
• Defective machines and tools. If a saw, press, conveyor or power tool was defectively designed or lacked adequate warnings, the manufacturer or distributor may be liable in a product liability lawsuit.
• Other contractors. On construction sites, a different company’s negligence can support a third-party claim.

Preserve evidence early: photos of the machine, the names of witnesses and any Cal/OSHA inspection.

What to do after a hand or wrist injury at work

1. Get medical care immediately, especially for crush injuries, deep cuts and amputations.
2. Report the injury in writing to your supervisor within 30 days.
3. Ask for and return the DWC-1 claim form. Your employer must provide it within one working day of learning about the injury (Labor Code 5401).
4. Photograph the injury and the equipment, and write down witness names.
5. Tell every doctor every symptom, including numbness, weakness and pain at night.
6. Keep records of pay, missed work, mileage and every letter from the insurer.
7. Get legal advice before a QME exam, before accepting a rating, and before signing a settlement.

If the claim isn’t denied within 90 days after you file the claim form, it is presumed compensable, and the insurer must pay up to $10,000 in treatment while it investigates (Labor Code 5402). The general deadline to file your case with the Workers’ Compensation Appeals Board is one year from the injury or the last benefit provided (Labor Code 5405).

Retaliation and your job after a hand injury

A hand injury claim is often the tip of the iceberg. Your employer cannot fire, demote or threaten you for filing a claim (Labor Code 132a). A successful 132a claim can increase your compensation by one-half, up to $10,000, plus reinstatement and lost wages. Under FEHA, your employer must also engage in the interactive process and reasonably accommodate restrictions such as no repetitive gripping or one-handed duty (Gov. Code 12940(m), (n)).

If you can’t return to your old job, ask about the $6,000 supplemental job displacement voucher and the state’s Return-to-Work Supplement Program. Our guide to vocational rehabilitation benefits after a work injury explains how they work.

Frequently asked questions

How much is workers’ comp for losing a finger in California?

There is no set amount. The payout depends on your permanent disability rating, which reflects which finger, how much was lost and how your hand functions, adjusted for your occupation and age. Your temporary disability and future medical care are separate.

Is carpal tunnel covered by workers’ comp?

Yes, when your work caused or contributed to it. It is usually treated as a cumulative trauma injury, and an EMG/NCS test is often key evidence.

Does it matter whether I hurt my dominant hand?

The rating focuses on measured loss of function, but losing use of your dominant hand can matter a great deal to whether you can return to your job, and that affects other benefits and your settlement.

Can I sue my employer if a machine cut off my finger?

Usually workers’ comp is the only remedy against your employer, but there are exceptions, including removed power press guards (Labor Code 4558). You may also have a claim against the machine’s manufacturer.

Will I be paid while I recover from hand surgery?

Yes. If your doctor takes you off work, or your employer can’t accommodate your restrictions, you should receive temporary disability, generally paid every two weeks.

Should I accept the insurer’s settlement offer?

Not before you understand your rating and future medical needs. See our guide on whether to accept a workers’ comp settlement offer.
