Can I choose my own doctor for a work injury in California?

Sometimes. Labor Code 4600(d) allows treatment by your own doctor from the date of injury if, before you were hurt, you told your employer in writing that you wanted your personal physician to treat a work injury, you had health coverage for non-work conditions on the date of injury, and the doctor agreed in advance. Without that predesignation, an employer or insurer with a medical provider network (MPN), a network of doctors approved by the Division of Workers’ Compensation (DWC), arranges the first visit with an MPN doctor. After that you can choose any doctor in the network (8 CCR 9767.6).

With no MPN, Labor Code 4600(c) lets you be treated by a doctor of your choice starting 30 days after the injury is reported.

What is a medical provider network?

An MPN is a group of doctors and other providers set up by an insurer or employer and approved by the DWC’s administrative director to treat injured workers (Labor Code 4616). The DWC’s MPN page says it must include doctors who mainly treat work injuries, meet access standards, follow the DWC’s treatment guidelines and offer second and third opinions.

Each MPN must post a roster of all its providers online and update it at least every quarter, and the DWC posts the web address of every approved MPN (4616(a)(4)). When an injury is reported, the employer or insurer must give you a written MPN notice that explains how to choose and change doctors (8 CCR 9767.12).

Who chooses the first doctor?

It depends on how your employer provides medical care and whether you predesignated.

Your situation	First doctor	Changing doctors later	Source
Valid predesignation	Your personal physician or medical group, from the date of injury	Your doctor’s referrals need not be in the MPN. A switch goes to an MPN doctor if there is an MPN	LC 4600(d); 8 CCR 9780.1; DWC guidebook ch. 3
Employer has an MPN	An MPN doctor the employer arranges	Any MPN doctor after the first visit, and again whenever reasonable	8 CCR 9767.6; DWC guidebook ch. 3
Employer uses a health care organization (HCO)	An HCO doctor	Within the HCO at least once, and outside it after 90 or 180 days, depending on whether you have employer-provided health insurance	DWC guidebook ch. 3
No MPN or HCO	Usually a doctor the claims administrator chooses	One change in the first 30 days, usually to a doctor the claims administrator chooses. A doctor of your choice after 30 days	LC 4600(c); DWC guidebook ch. 3

How do you predesignate a personal physician?

You predesignate by giving your employer written notice before any injury, with the doctor’s name and business address and the name of your health plan (8 CCR 9780.1). You can write your own statement, use your employer’s form or use the optional DWC Form 9783.

Three conditions apply under Labor Code 4600(d). You must have health coverage for non-work injuries and illnesses on the date of injury. The doctor must be your regular physician and primary care physician, who has directed your care before and keeps your medical records. A qualifying multispecialty medical group can count. And the doctor must agree in advance, which the doctor can show by signing the form.

If the doctor agreed before the injury but the employer had no proof of it yet, treatment starts under the usual rules and moves to the predesignated doctor once the documented agreement is provided (9780.1(h)). Unless you agree, neither the employer nor the claims administrator may contact that doctor to confirm the predesignation or ask about your medical history before treatment starts (9780.1(e)).

A valid predesignation means the MPN does not apply to you for that injury (9780.1(c)). Chiropractors and acupuncturists cannot be predesignated. But when the employer has no MPN, a worker who named a personal chiropractor or acupuncturist in writing before the injury, for example on DWC Form 9783.1, can switch to that provider on request after a first visit with a doctor the claims administrator chose (DWC guidebook; 8 CCR 9781(b)(2)).

Can you change doctors inside the MPN?

Yes. After the first evaluation with an MPN doctor, you may choose any MPN physician whose specialty fits the injury (8 CCR 9767.6(e)). The DWC guidebook says you may switch again whenever it is reasonable. The employer or insurer must tell you about this right and how to see the provider list (9767.6(d)).

Every MPN must have medical access assistants to help you find a doctor and schedule appointments. They must be based in the United States and available Monday through Saturday from 7 a.m. to 8 p.m. Pacific time (8 CCR 9767.5(h)). The network must have three available primary treating physicians (the doctors in charge of your care) within 30 minutes or 15 miles of your home or work. It must also have occupational health providers and doctors in the specialties that treat common injuries within 60 minutes or 30 miles. A first treatment visit must be available within 3 business days of asking an access assistant, and a first visit in another needed specialty within 20 business days.

How do second and third opinions work?

If you dispute the diagnosis or treatment from your MPN doctor, you may get a second and then a third opinion from other MPN doctors (8 CCR 9767.7). For each one, you tell the person the employer or insurer designates, in writing or orally. Then you choose a doctor from the MPN list, make the appointment within 60 days of receiving the list and report the date. Missing the 60 days waives that opinion. Each opinion doctor must serve a written report within 20 days of the appointment, or of any test results if later (9767.7(f)).

If you still disagree after the third opinion, you can request an MPN independent medical review from the DWC administrative director (9767.7(h)). The DWC guidebook says that if the reviewing doctor agrees with you, you may get the treatment from a doctor outside the MPN.

This review is separate from the independent medical review that follows a utilization review denial. Utilization review is the claims administrator’s review of a doctor’s treatment request. Labor Code 4062(b) and (c) send each kind of dispute down its own path.

When can you be treated outside the MPN?

The MPN regulations open the door outside the network in specific situations (8 CCR 9767.5):

• The MPN cannot provide needed treatment within the access standards and time limits.
• An access assistant cannot schedule a needed specialty appointment within ten business days of your request.
• Your treating doctor refers you to a specialty the MPN does not include.
• You need emergency care.
• A second or third opinion recommends treatment no MPN doctor can provide (9767.7(g)).

Labor Code 4600(a) adds a general rule: if the employer neglects or refuses to provide reasonable treatment, it is liable for the reasonable cost of treatment you obtain.

What do people get wrong about choosing a doctor?

“My family doctor can take over whenever I want.” Only with a valid predesignation made before the injury (Labor Code 4600(d)).

“The clinic my employer sent me to is my doctor for the whole claim.” In an MPN, you can choose another MPN doctor after the first visit (8 CCR 9767.6(e)).

“Predesignation works without health insurance.” It requires coverage for non-work conditions on the date of injury (4600(d)(1)).

“A second opinion is a QME.” MPN second and third opinions are about your diagnosis and treatment. A qualified medical evaluator (QME) handles disputes such as whether the injury is work-related and how disabled you are.

Where does the Law Office of Jesse Melendrez fit in?

Treatment questions often come down to which rule applies: whether a predesignation was valid, whether the MPN met its access standards, or which review path a dispute belongs in. When we represent an injured worker, sorting that out and taking unresolved disputes to the appeals board is part of our work. Jesse Melendrez (State Bar of California #263751, admitted 2009) limits his practice to California workers’ compensation and represents injured workers only.
