Labor Code 4600 Medical Treatment Duty

What the Treatment Duty Means

Medical treatment is one of the core benefits in a workers compensation claim. The duty can include doctor visits, therapy, medication, imaging, surgery, equipment, or other care when supported by the medical record.

The phrase in the statute is often disputed. In practice, the worker needs a treating doctor request, a clear diagnosis, and records showing why the care is needed for the work injury.

The claims administrator may use UR to approve, modify, or deny treatment. That decision should be in writing.

What to Check

Check the treatment request, UR decision, denial reason, and appeal or IMR information if provided. Save all dates.

Also check whether the treating doctor used the correct body part and described the work injury clearly.

Records That Help

Save wage records, pay stubs, time sheets, disability payment notices, doctor work-status notes, and letters from the claims administrator. Keep the envelope or email date when a notice may affect timing.

Make a simple payment log. List the date each check arrived, the period it covered, and the amount paid. If a payment is missing, write down the date you expected it and the date you asked about it.

Keep medical and wage papers together but separated by type. Medical records explain work limits. Wage papers explain the rate. Both are usually needed when a payment amount is disputed.

Common Problems

Problems include delayed authorization, denied therapy, missing medical records, wrong body part coding, or disputes over whether treatment is tied to the work injury.

Do not rely only on what the clinic says by phone. Ask for written authorization or denial when possible.

Steps to Take Now

Start with the basic documents. Save the latest doctor note, the most recent payment notice, and the wage records from before the injury. Put them in date order.

Make a one-page timeline. Include the injury date, first missed work date, first payment date, any payment stop date, and each date when the claims administrator sent a notice.

Write down the issue in plain words. Examples include wrong rate, late payment, missing overtime, denied care, wrong doctor, or no clear explanation. A short label helps focus the review.

Ask for the calculation or decision in writing. If the adjuster gives an answer by phone, send a short follow-up email that repeats what you understood and asks for correction if needed.

Keep copies of forms, not only screenshots. A full copy often shows dates, claim numbers, and fine print that a cropped image misses.

If the dispute involves wages, bring several pay periods. If the dispute involves care, bring the doctor request and the written approval, delay, or denial.

Before signing settlement papers, compare the settlement with the payment log, medical report, and any future care language. If something is missing, ask before signing.

Questions to Ask

Ask what rule the claims administrator used. Ask what dates were used. Ask what records were missing, if any. These questions are simple, but they often reveal the real dispute.

Ask whether the decision can be corrected with documents. A missing wage record, doctor note, or form may be easier to fix than a full legal fight.

If the answer is still no, save the denial and ask what review process applies. The next step may be different for payment, rating, doctor choice, treatment, or timing disputes.

Bring all notices to a lawyer before a deadline passes. A short review can identify whether the issue is urgent and what document should be filed next.
