Medical treatment and the MPN

The most common question injured workers ask: can I see my own doctor? The answer is that it depends almost entirely on whether your employer has a Medical Provider Network — and today, nearly all of them do.

  1. File a written predesignation (DWCDWC Division of Workers’ Compensation, part of the Department of Industrial Relations. Administers the system. Information Services Center: 1-800-736-7401. Form 9783) with your employer before you are ever injured and you treat with your own doctor from the date of injuryDate of injury For a cumulative or occupational disease claim, the law sets it as when you first suffered disability and knew or should have known it was work-related — not when the wear began. Almost every deadline runs off this. — no network, no control period. There is no cure for missing it.

The appeal from a UR denial. 30 days (10 if the dispute is only over drugs on the MTUS Drug List).. Most workers never learn steps two through four exist.
  3. The law covers whatever is “reasonably required to cure or relieve” — palliative care qualifies. Where the employer neglects or refuses care, it is liable for treatment you obtain yourself. And up to $10,000 must be authorized while the claim is undecided.

The one thing to do before you are ever injured: a written predesignation. It takes one form. Almost nobody does it, and of the people who try, many get it wrong. The five requirements are below.

What you are owed

LABOR CODE § 4600

“Medical, surgical, chiropractic, acupuncture, licensed clinical social worker, and hospital treatment, including nursing, medicines, medical and surgical supplies, crutches, and apparatuses, including orthotic and prosthetic devices and services” — whatever is reasonably required to cure or relieve you from the effects of the injury.

“CURE OR RELIEVE”

Palliative care qualifies. Treatment does not have to fix anything, and you do not have to prove your condition is curable. A claim that treatment is “only palliative” is not, by itself, a valid denial.

“NEGLECTS OR REFUSES”

Where the employer neglects or refuses to seasonably provide treatment, it is liable for the reasonable expense of treatment you obtain yourself — the basis for reimbursement of self-procured care, enforced in Braewood Convalescent Hospital v. WCABWCAB Workers’ Compensation Appeals Board. The court system that decides these cases. 23 district offices statewide. (1983).

WHILE THE CLAIM IS UNDECIDED

Up to $10,000 in treatment must be authorized within one working day of your filing a claim form, and continues until liability is accepted or rejected — it does not wait for the claim to be decided.

The Medical Provider Network

An MPN is a list of physicians the employer or insurer has assembled. If your employer has one, your treatment generally has to come from inside it. The access standards are real and enforceable: a primary treating physicianPTP Primary Treating Physician. The doctor directing your care. within 30 minutes or 15 miles of your residence or workplace, an occupational health specialist and hospital within the same standard, and specialists within 60 minutes or 30 miles. The notice requirements are also real — written notice of the MPN, how to find and change physicians, and how to dispute a treatment decision, including at the time of injury.

Changing doctors inside the network

  1. Change to any other physician in the network, at any time, without permission.
  2. Get a second opinion from a network physician if you disagree with your treating physician’s diagnosis or treatment plan.
  3. Get a third opinion if you still disagree.
  4. Request MPN Independent Medical Review if the third opinion does not resolve it.

You do not need anyone’s approval to switch to a different doctor within the network — and if the relationship with your treating physician has broken down, that is often the fastest fix available.

Getting out of the network

PREDESIGNATION

The cleanest route, and it must be set up in advance — below.

THE CLAIM IS DENIED

If the employer rejects liability, it is not directing your care.

DEFECTIVE MPN NOTICE THAT CAUSED A DENIAL OF CARE

Under Knight v. UPS (WCAB en banc, 2006), an employer’s failure to give proper MPN notice can cost it control of treatment where that failure resulted in a neglect or refusal to provide care. The 2012 reforms narrowed this — a technical defect alone is no longer automatically enough.

ACCESS FAILURE

If the network cannot actually deliver a physician meeting the access standards, in the right specialty, within a reasonable time, it is not functioning as a network.

MPN IMR · CONTINUITY OF CARE

A favorable MPN Independent Medical Review determination. And in defined circumstances, ongoing treatment with an outside physician can be continued rather than transferred.

NOT A ROUTE OUT

Simply preferring a different doctor. That is not a basis, and being told otherwise sets people up for unpaid bills.

Predesignation — the form to file before anything happens

The law gives you the right to treat with your own physician from the date of injury if you notified your employer in writing before the injury and you have non-occupational health coverage. Five requirements, all of which must be satisfied before you are hurt:

#REQUIREMENT
1Written notice to your employer before the date of injury, naming your personal doctor and business address. DWC Form 9783 is the safe harbor
2You have non-occupational health coverage on the date of injury — a health plan, qualifying group disability policy, or Taft-Hartley fund
3Your doctor qualifies as a “personal physician” — your regular M.D. or D.O. who has previously directed your treatment and retains your records, in general practice, internal medicine, pediatrics, OB/GYN, or family practice. A qualifying medical group counts
4Your physician agreed, before the injury, to treat you for work injuries. The form has a signature block; if the doctor does not sign, you need other documentation
5The notice actually reached your employer before the injury. Keep a dated copy and proof of delivery

An old rule to set aside: predesignation once required that your employer offer group health insurance. The current statute requires only that you have non-occupational health coverage on the date of injury — from any qualifying source, including a spouse’s plan or a policy you bought yourself.

Predesignation beats the MPN, because the right operates “from the date of injury” — there is no employer control window at all. The employer does retain utilization reviewUR Utilization Review. The process that approves, modifies, or denies each treatment request. A modification is a denial of what it left out. rights over what your doctor requests. There is no cure for missing this. File it before the injury or the right is gone. If you have a doctor you trust and a job with any physical risk, this is worth twenty minutes this week. A separate and weaker right exists for predesignating a personal chiropractor or acupuncturist, but it works only where the employer has no MPN.

If your employer has no MPN

Then the older rules apply, and they are more generous. One free change of physician on request — the claims administratorClaims administrator / adjuster The person handling your claim for the insurer or self-insured employer. must provide an alternative physician no later than 5 working days from receiving your request. And after 30 days from the date the injury is reported, you may treat with a physician of your own choice within a reasonable geographic area; on notice, the claims administrator has 20 days to authorize.

Note the trigger: 30 days from when the injury is reported, not from the date of injury. “You can choose your own doctor after 30 days” holds only where there is no MPN — and almost the entire insured market operates one.

Your primary treating physician, and the 24-visit caps

You have one primary treating physician at a time. That doctor is responsible for your overall care, for writing the reports that drive your case, and for requesting authorization for treatment. The Doctor’s First Report, the periodic PR-2 reports, and the permanent and stationaryP&S / MMI Permanent and Stationary / Maximum Medical Improvement. Your condition has plateaued — not that you are healed. Temporary disability ends here. report are the documentary spine of your claim — they determine your work status, your restrictions, and ultimately your impairment. A treating physician who does not write, or writes thinly, damages your case even if the medical care is fine. That is a legitimate reason to change doctors.

For injuries on or after January 1, 2004, you are generally limited to 24 chiropractic visits, 24 physical therapy visits, and 24 occupational therapy visits per industrial injury. The employer may authorize more in writing, and post-surgical physical medicine is treated separately. After 24 chiropractic visits, a chiropractor generally cannot continue as your primary treating physician without written authorization.

Things you are owed that nobody mentions

MILEAGE

76¢ per mile for travel on or after July 1, 2026 (72.5¢ for the first half of the year). Keep a log: dates, destinations, round-trip miles. It adds up faster than people expect over a long claim.

INTERPRETERS

For medical treatment appointments and medical-legal evaluations. You pay nothing.

TRANSPORTATION, PARKING, LODGING, MEALS

For treatment travel, in some circumstances.

HOME HEALTH CARE

Where medically necessary and prescribed, subject to the requirements of § 4600(h).

YOUR OWN DOCTOR, AT YOUR OWN EXPENSE

You may always consult a physician of your choosing at your own cost, and that physician’s report can be used as evidence — though it cannot be the sole basis for an award.

What to do now

  • Ask, in writing, whether there is an MPN — Keep the response. A failure to give proper notice can matter later.
  • If you are still working and uninjured, file the predesignation this week — DWC Form 9783, signed by your doctor, delivered with proof.
  • If you dislike your doctor, switch inside the network — Any network physician, any time, no permission needed.
  • Start the mileage log — Every visit, every mile, parking and tolls.

Frequently asked questions

Can I see my own doctor?

Only if you predesignated before the injury, your employer has no MPN and 30 days have passed since you reported, the claim is denied, or one of the other exits above applies. Otherwise, treatment comes from within the network.

I don’t like my doctor. Can I switch?

Within an MPN, yes — to any other physician in the network, at any time, without permission. This is the most under-used right in the system.

My doctor requested treatment and it was denied.

That is utilization review, and it has its own deadlines and its own defects worth checking.

Do I have to use the network doctor the adjuster suggested?

No. You may pick any physician in the network. An adjuster steering you toward a particular doctor is not the same as a requirement.

How do I find out if there is an MPN?

The employer is required to give you written notice. Ask in writing and keep the response — a failure to give proper notice can matter later.

Can I be reimbursed for treatment I paid for myself?

Sometimes — where the employer neglected or refused to provide care. It is fact-specific and worth asking about before you spend.

Is treatment covered while my claim is denied?

Up to $10,000 must be authorized within one working day of filing your claim form and continues until liability is accepted or rejected. After a denial, you generally use health insurance or EDD while the case is litigated — and if you win, treatment is covered retroactively.
