Workers’ comp medical treatment is the care an employer must provide that is reasonably required to cure or relieve the effects of a work injury, measured by the state’s treatment guidelines (Labor Code 4600(a), (b)). It is owed whether or not the worker misses time from work (DWC).
A workers’ comp medical treatment lawyer in Orange County deals with the problems that block that care: the wrong doctor, a network that cannot schedule, a denied request, or a claims administrator that has not authorized anything. The Law Office of Jesse Melendrez represents injured workers on these medical issues in Orange County, Los Angeles, Riverside and San Diego.
Who picks the doctor after a work injury?
It depends on predesignation and on whether the employer uses a medical provider network (MPN).
| Situation | Who treats | Source |
|---|---|---|
| Personal physician predesignated in writing before the injury | That physician or medical group, from the date of injury | Labor Code 4600(d) |
| Employer or insurer has an MPN | An MPN doctor first; after the first visit, another MPN doctor of the worker’s choice | Labor Code 4616; DWC |
| No predesignation and no MPN or HCO | The claims administrator’s choice for 30 days after the injury is reported, then the worker’s choice within a reasonable area | Labor Code 4600(c) |
| Mileage to treatment | 72.5 cents a mile from January 1, 2026; 76 cents from July 1, 2026 | DIR benefits table |

How does a medical provider network work?
An MPN is a group of doctors set up by an insurer or self-insured employer and approved by the DWC (Labor Code 4616(a)(1), (b)(1); DWC). Each MPN must post a roster of its providers online and update it at least every quarter (Labor Code 4616(a)(4)).
Each MPN must also have medical access assistants, reachable at a toll-free number at least from 7 a.m. to 8 p.m. Pacific time, Monday through Saturday, to help workers find a doctor and schedule appointments (Labor Code 4616(a)(5)).
After the first visit, the worker may switch to another doctor in the MPN. A worker who disagrees with an MPN doctor’s diagnosis or treatment can get a second and a third opinion inside the network, then an MPN independent medical review (DWC; Labor Code 4062(c)). The DWC’s guidebook says the second and third opinion appointments must be made within 60 days of receiving the list of doctors, and that when the MPN reviewer agrees with the worker, the treatment can be obtained outside the MPN (Guidebook, chapter 4).
What is predesignation?
Predesignation lets a worker keep a personal doctor for a future work injury. It must be given to the employer in writing before the injury, the worker must have health coverage for non-work conditions on the date of injury, and the doctor must be the worker’s regular physician who has directed the worker’s care, keeps the records and agrees to be predesignated (Labor Code 4600(d)). A medical group can also be predesignated.
The DWC’s form for this is the Notice of Predesignation of Personal Physician, DWC Form 9783.
Where do treatment disputes go?
Treatment disputes take different tracks depending on what is disputed. A denied or modified treatment request goes through utilization review and then independent medical review (Labor Code 4610, 4610.5); the utilization review page covers it. A disagreement with an MPN doctor goes through second and third opinions and MPN IMR (Labor Code 4062(c)).
Whether the worker must treat inside the MPN, and disputes over a medical appointment, can go to an expedited hearing, with a decision due within 30 days of the declaration of readiness (Labor Code 5502(b)(2), (3)). Unreasonable delay in treatment can carry a penalty of up to 25 percent of the delayed amount, capped at $10,000 (Labor Code 5814(a)).
How does the firm work a medical treatment problem?
We start by finding out which set of rules governs the claim.
- Confirm whether an MPN applies, and get the MPN’s notices and roster from the claims administrator.
- Check for a written predesignation made before the injury.
- Help you change to another MPN doctor or a doctor of your choice when the rules allow, and use the second and third opinion steps when they do not.
- Track the treatment requests, the UR decisions and the IMR deadlines.
- Ask for an expedited hearing when the dispute is about MPN access or a medical appointment (Labor Code 5502(b)(2), (3)).
- Keep interpreter rights in view: on request, the employer pays for a qualified interpreter at treatment appointments when the worker cannot communicate well in English (Labor Code 4600(g)).
Every benefit is on the benefits page.
There is no upfront cost. Attorney fees in a California workers’ compensation case are set and approved by a workers’ compensation judge and are paid out of the benefits recovered. Which doctor rules apply to a claim depends on its facts, which is what the first conversation sorts out.
