Usually you treat inside the employer's medical network, but you can switch among its doctors. A doctor you named in writing before the injury is the key exception.
You got hurt at work. You have a doctor you trust. Now you are told you cannot just go see them. That feels wrong, and it raises a fair question.
The honest answer is: it depends. California gives the employer's insurer a lot of control over which doctors treat you. But you still have rights and choices inside that system.
Knowing the rules early protects your care. The wrong move can leave you stuck with a doctor who is not on your side.
An MPN is the network of doctors the insurer approves for work injuries. In most cases you must treat inside it, but you can switch among its doctors freely.
Most California employers use a Medical Provider Network, or MPN. It is set up under Labor Code 4616. The MPN is a list of doctors the insurer has approved to treat work injuries.
If your employer has a valid MPN, you must treat inside it. That is the general rule. But the rule has a real upside. You are not stuck with one doctor. You can pick any doctor in the network. If you do not like them, you can switch to another.
You can also get a second opinion inside the MPN. If you still disagree, you can get a third. This gives you more room than many workers realize.
You can use your own doctor if you pre-designated them in writing before the injury, or if the employer had no valid network in place.
There are clear exceptions to the network rule. The table below lays them out.
| Situation | Can you use your own doctor? |
|---|---|
| You pre-designated your doctor in writing before the injury | Yes, from day one (Labor Code 4600(d)) |
| Employer has no valid MPN | Yes, you may treat with your own doctor |
| Employer did not provide care within the first day | You may gain more control after 30 days |
| Valid MPN exists, no pre-designation | No, but you can pick any MPN doctor |
Pre-designation is powerful, but it has rules. You must have named the doctor in writing before you got hurt. The doctor must be your regular physician and must agree to treat you. Most workers never do this, so the chance is gone once the injury happens.
Inside the MPN, you can change to another network doctor at any time. You do not need permission to switch.
Sometimes a doctor seems to side with the insurer. They may rush you back to work or deny that your pain is real. You do not have to stay with them.
You can change to another doctor in the MPN whenever you want. Ask the insurer or claims adjuster for the current MPN list. Then pick a new doctor and book a visit. Your care under Labor Code 4600 is meant to make you better, not to serve the insurer.
Ask the claims adjuster for the MPN list and website. By law they must give you access to the network directory and help you find a doctor.
You cannot pick a network doctor if you do not know who is in the network. So start by asking. Request the MPN name, website, and contact in writing from the claims adjuster.
The MPN must provide a medical access assistant to help you. They can find doctors and book appointments for you. If the insurer drags its feet or hides the list, write down each attempt. A network that blocks your access to care may not be valid, and that opens the door to treating outside it.
Many employers send you to an industrial clinic on day one. After that first visit, you can switch to a different doctor inside the MPN.
Right after an injury, employers often send you to a chosen clinic. That first visit is normal. It gets you treated fast. But you are not stuck there.
Once your care begins, you can move to any other doctor in the network. If the clinic seems focused on rushing you back to work, switch. You are allowed to find a network doctor who takes your injury seriously.
You can switch to another network doctor for a fresh opinion. If a real dispute remains, a QME can settle the medical question.
Some network doctors lean toward the insurer. They may release you to full duty while you are still in pain. That can cut off your benefits before you have healed.
You do not have to accept it. First, switch to a different doctor inside the network and get a new opinion. Be clear and honest about your symptoms. If your new doctor and the insurer still disagree, the dispute can go to a Qualified Medical Evaluator. That neutral doctor gives an independent opinion. Keep notes on your pain and limits along the way. A clear record helps your case if the fight reaches that stage.
