What Is a Primary Treating Physician (PTP) in California Workers' Compensation?

What does your PTP control in your claim?

Your PTP directs your treatment, sets your work limits, starts your wage checks, and writes the report that decides your disability rating.

Your PTP runs the whole show. Under Labor Code 4600, this doctor directs your care. That care is fully covered with no copay.

Here is what your PTP controls.

Almost every benefit flows from these reports. That is why this one doctor matters so much.

One report carries real weight. When your PTP writes that you cannot work, your wage checks should start. These checks are called temporary disability, or TD. They replace part of the pay you lost while you heal.

Here is what TD pays in 2026.

You should get your first check fast. Tell us if your checks are ever late.

One warning. Your PTP can ask for care, but the insurer can still push back. They use a process called utilization review. If they deny needed care, you can appeal. A short deadline applies, so call a lawyer fast.

How is the PTP different from a QME?

Your PTP treats you over time. A QME is a one-time neutral doctor who settles a dispute about your benefits or rating.

Your PTP is your real doctor. They see you, treat you, and know your case well.

A QME is different. QME stands for Qualified Medical Evaluator. You see this doctor only once. This happens when you and the insurer disagree about your claim.

You do not get to pick any QME you want. You choose from a 3-name state panel. Each side strikes one name under Labor Code 4062.2. If you have a lawyer, the two sides can agree instead. They pick one shared doctor.

You may see the QME only once. So that single visit really counts. Bring your full history. Describe every symptom and every limit. Do not downplay your pain to seem tough.

So your PTP heals you. A QME just gives an opinion to break a tie. Both can affect your rating, so both reports must be strong.

Watch for one trap. If a QME report is wrong, it can lower your benefits. You can object to a bad report. A lawyer can help you fight it.

How do you change your PTP inside the MPN?

After your first visit, you may switch to another doctor inside your employer's Medical Provider Network. You do not need anyone's permission.

Most claims use a Medical Provider Network, or MPN. This is a list of approved doctors set by Labor Code 4616. Your employer's insurer usually picks your first doctor from this list.

You are not stuck with that doctor. After the first visit, you can choose any other doctor in the MPN. Ask the insurer for the MPN list or its website.

Switching is smart when your doctor will not listen. Maybe they rush you. Maybe they clear you for work too soon. A new PTP inside the MPN can take over your care.

You had one more right before you got hurt. Under Labor Code 4600(d), you can name your own doctor in writing. You must name them before the injury. Few workers know this, so most stay inside the MPN.

Bring someone you trust to visits if you can. A second set of ears helps. Write down what the doctor says. Good notes protect you later.

Why do PTP reports decide your disability rating?

When you stop improving, your PTP writes a final report with an impairment number. That number sets your permanent disability and your pay.

At some point your body heals as much as it will. Doctors call this permanent and stationary. Your PTP then writes a final report.

This report gives an impairment number for your lasting injury. A rater turns that number into a percent from 0 to 100. The percent can move up or down for your age and your job.

That percent decides how many weeks you get paid under Labor Code 4658. Here is what each rating pays at the 2026 maximum.

A rating of 70% or more adds a lifetime life pension. A strong PTP report is worth real money to you.

This is where a good lawyer helps most. A vague PTP report can cost you thousands. We make sure the report fits your real limits.

Ask questions at every visit. Make sure the doctor writes down all your injuries. A body part left out can lower your rating. Speak up if the report misses something.

Save copies of every report. Ask your PTP for a copy after each big visit. Read it to be sure it matches your pain and your limits. If something is wrong, tell the doctor right away.
