If your workers' comp doctor gave you a rating or a report you do not believe is accurate, you are not stuck. California law gives you specific tools to challenge that report, change your doctor, or force an independent medical review. But the path is not the same as asking for a second opinion at your regular doctor's office. The rules are set by the California Labor Code, and the choices you make in the next few weeks can directly change the dollar value of your settlement.
Here is exactly what your options are, what the process looks like, and what to do if you think the medical report is costing you money.
Quick answers for skimmers:
- You can request a new treating doctor inside your employer's MPN (Medical Provider Network) at any time under Cal. Lab. Code §4616.3.
- If you disagree with a medical-legal report, you or your employer can object in writing, which triggers a QME (qualified medical evaluator) panel assigned by the DWC (Division of Workers' Compensation) under Cal. Lab. Code §4062.2.
- Once a QME panel is issued, each side has 10 days to strike one doctor from the list; the remaining doctor becomes the panel QME.
- An AME (agreed medical evaluator) is an alternative to the QME panel, a single doctor both sides choose voluntarily when they are represented by attorneys.
- The QME or AME report feeds directly into your permanent disability (PD) rating, which determines your settlement under Cal. Lab. Code §4658.
- There is no informal "second opinion" in California workers' comp, only these formal legal paths.
Your Right to Change Your Treating Physician Inside the MPN
Most California employers use a Medical Provider Network, a list of pre-approved doctors that you must use for treatment if your employer properly notified you of the MPN at the time of hire or injury. Being inside an MPN does not mean you are locked into one doctor forever.
Under Cal. Lab. Code §4616.3, you can ask to switch to a different treating physician within the MPN. You do not need to show that your current doctor did anything wrong. You simply make the request. The law requires your employer or its insurance carrier to provide you with a list of available MPN physicians in your geographic area so you can choose.
Why this matters: If your current treating doctor has been giving you conservative treatment, minimizing your restrictions, or producing reports that seem to help the insurance carrier more than they help you, a new MPN physician may take a different view of your condition. The new doctor starts fresh. Their treatment notes and reports become part of your claim file alongside everything that came before.
A few practical points about switching within the MPN:
- The MPN must have enough physicians in your specialty and area to make a real choice possible. If the network is too thin in your specialty, you may have rights outside the MPN under Cal. Lab. Code §4616.3.
- The new doctor reviews your prior records, but they form their own clinical judgment. A new treating physician is not required to agree with the prior one.
- If you were never properly notified about the MPN, you may have the right to treat with your own personal physician instead. This is a fact-specific question, call us at 818-794-9947 to walk through your specific situation.
If you are not in an MPN, you have broader rights to choose and change your physician under Cal. Lab. Code §4600, which governs medical treatment in the workers' comp system generally.
QME vs. AME: When a Dispute Goes to an Independent Evaluator
Changing your treating doctor is different from challenging a medical-legal report. When either side disagrees with a medical opinion that affects the legal outcome of your claim, the formal dispute path leads to either a QME or an AME.
What is a QME?
A QME is a physician certified by the DWC to perform medical-legal evaluations in workers' comp cases. When a dispute arises over a medical issue, the DWC issues a panel of three QME physicians in the appropriate specialty. Each side then has 10 days to strike one doctor from that panel under Cal. Lab. Code §4062.2. The doctor who remains after those strikes becomes the panel QME and performs the evaluation. Their written report carries significant weight at the WCAB (Workers' Compensation Appeals Board).
If you disagree with the medical report from your treating doctor, the formal path is to file a written objection, which triggers a QME panel of three physicians assigned by the DWC under Cal. Lab. Code §4062.2.
Once a QME panel is issued, each side has 10 days to strike one physician from the list, the remaining doctor becomes the panel QME.
What is an AME?
An AME is an agreed medical evaluator, a single doctor that both sides choose together, without going through the state panel process. The AME option is only available when both the injured worker and the employer or insurance carrier are represented by attorneys. When both sides can agree on a single evaluator with the right credentials and specialty, the AME process is often faster and gives both parties a degree of control over who examines the injured worker.
A QME is a state-assigned panel doctor, while an AME is a single evaluator both sides agree on voluntarily, either way, their report drives your permanent disability rating.
QME vs. AME, side-by-side comparison
| Factor | QME | AME |
|, |, |, |
| How the doctor is chosen | DWC-issued panel, then each side strikes one | Both sides agree on one doctor |
| Attorney required? | No, but strongly recommended | Yes, required for AME option |
| Who can use it? | Any party to the claim | Represented parties only |
| Timeline | State controls panel issuance; evaluation scheduled after strikes | More flexible, parties schedule directly |
| Cost | Fees set by DWC | Fees negotiated but typically similar |
When is the QME process triggered?
The dispute process is set out in Cal. Lab. Code §4062 and §4062.2. Either party, you or the insurance carrier, can object in writing to a medical determination made by the treating physician. Common reasons to object include:
- A permanent disability rating you believe is too low
- A conclusion that your injury is not work-related when you believe it is
- An opinion that you have reached maximum medical improvement (MMI) before you feel you have recovered
- A determination that certain treatment is not medically necessary when your own doctor says it is
The written objection starts a clock and a procedural sequence. Getting the timing and the form of the objection right matters. Missing a deadline or filing the wrong type of objection can affect your rights. This is one of the most important moments to have an attorney on your side.
What to Do When the Treating Report Undervalues Your Injury
If you received a report from your treating doctor that seems to minimize your injury, minimize your restrictions, or give you a lower permanent disability rating than you expected, here is what to do.
Step 1: Read the report carefully. Look at the diagnosis, the work restrictions, the apportionment percentage (if any), and the permanent disability rating. Note every factual claim that seems wrong or incomplete.
Step 2: Tell your attorney what you disagree with. If you do not have an attorney yet, this is the moment to call one. The medical-legal reports in your file will drive the outcome of your claim. You want a specialist reviewing the report before the objection window closes.
Step 3: Understand what a formal objection accomplishes. Filing a written objection to a treating physician's report does not simply get you a different treating physician's opinion, it triggers the QME or AME evaluation process described above. That independent evaluator's report then becomes the controlling medical-legal opinion on the disputed issue for your claim.
Step 4: Get your own records in order. If you have seen a personal physician or specialist outside the workers' comp system, those records can be provided to the QME or AME evaluator. An independent evaluator considers all medical evidence, not only the records generated inside the workers' comp claim.
Step 5: Attend the evaluation prepared. The QME or AME evaluation is a medical-legal examination, not a regular doctor's appointment. The evaluator is reviewing your condition to write a report for the court, not to treat you. You should describe all of your symptoms, limitations, and how your injury affects your daily life and your ability to work. Understating your symptoms at this examination can reduce your rating.
In California, injured workers covered by an employer's Medical Provider Network can request a change of treating physician within the network at any time under Cal. Lab. Code §4616.3.
How Medical Reports Drive Your PD Rating and Settlement
This is the connection that most injured workers do not fully understand until it is too late. The permanent disability rating assigned to your injury is not just a medical number, it is the formula that sets the dollar value of your permanent disability benefit under Cal. Lab. Code §4658.
The rating system uses the AMA Guides to the Evaluation of Permanent Impairment (Fifth Edition) as adjusted by California's workers' comp rating schedule. The treating physician's reports, and then the QME or AME report if there is a dispute, feed directly into that rating.
A difference of just a few percentage points in your permanent disability rating can translate into thousands of dollars in additional benefits. Here is why the medical report matters so much:
- Higher WPI (whole person impairment) percentage from the QME or AME results in a higher PD rating.
- Work restrictions that limit what jobs you can return to affect the PD rating calculation.
- Apportionment, if the evaluator says only a portion of your disability is from this injury (versus a prior injury or non-industrial condition), that reduces the benefit the employer owes. Under Cal. Lab. Code §4664, the employer is not liable for the portion of disability caused by prior impairment. Challenging an apportionment opinion you believe is wrong is one of the most valuable things an attorney can do for you.
- MMI determination, once the evaluator says you have reached maximum medical improvement, your treatment rights narrow. If you believe that determination is premature, contesting it through the QME or AME process may preserve your right to additional medical treatment.
The treating physician's reports and the QME or AME evaluation directly determine your permanent disability rating under Cal. Lab. Code §4658, which sets the dollar value of your settlement or award.
California workers' comp does not have an informal second-opinion process, your legal options are a physician change within the MPN or the formal QME or AME dispute path.
What This Means for Your Settlement
Most California workers' comp cases resolve through one of two paths: a Compromise and Release (C&R), a lump-sum payment that closes the claim entirely, or a Stipulation with Request for Award, which preserves some future medical rights while paying the PD benefit in installments.
In either case, the permanent disability rating established by the medical-legal reports is the baseline the insurance carrier uses when calculating what to offer you. A carrier that has a treating physician report giving you a 10% PD rating and no disputed QME will offer a settlement consistent with that number. If a QME or AME comes in with a 20% PD rating, the settlement value changes substantially.
The insurance carrier knows this. Their adjusters monitor the medical-legal reports in your file from the beginning. When a report is favorable to the carrier, they often move quickly toward settlement. When a dispute is filed and a QME is pending, the calculation shifts.
We have recovered over $150,000,000 for injured California workers. A large portion of that recovery came from cases where the initial treating physician report undervalued the injury, and the QME or attorney review changed the outcome.

FAQ
Can I get a second opinion in workers' comp in California?
Not in the traditional sense. California workers' comp does not have an informal second-opinion process like private health insurance. Your options are: (1) request a change of treating physician within the MPN under Cal. Lab. Code §4616.3, or (2) file a written objection to a medical-legal report, which triggers the QME panel process under Cal. Lab. Code §4062.2. Both paths are formal and procedural. An attorney can help you choose the right one for your situation.
How do I change my treating doctor in workers' comp in California?
If your employer has an MPN, you can request a new treating physician within the network at any time under Cal. Lab. Code §4616.3. Your employer's insurance carrier must provide you with a list of available MPN physicians. If you were never properly notified about the MPN, you may have the right to choose your own doctor. If there is no MPN, Cal. Lab. Code §4600 governs your right to medical treatment and physician selection.
What if I disagree with my workers' comp doctor's report?
You can file a written objection to the treating physician's report. Once an objection is filed on a medical-legal dispute, the process under Cal. Lab. Code §4062 and §4062.2 is triggered. The DWC issues a panel of three QME physicians in the appropriate specialty. Each side has 10 days to strike one name from the panel, and the remaining doctor performs the independent evaluation. Their report then carries significant legal weight in your case.
What is the difference between a QME and an AME in California workers' comp?
A QME (qualified medical evaluator) is a state-certified physician assigned through a DWC panel when the parties cannot agree on a doctor. A panel of three is issued and each side strikes one. An AME (agreed medical evaluator) is a single physician both sides voluntarily select together, this option is only available when both sides have attorneys. Both types of evaluators produce medical-legal reports that determine disputed issues like your permanent disability rating.
Can the insurance company also get a second opinion?
Yes. Either party, the injured worker or the employer and its insurance carrier, can object to a treating physician's medical determination and trigger the QME process under Cal. Lab. Code §4062.2. This is one reason why acting quickly when you receive a favorable treating physician report matters. An attorney can help protect the record and respond appropriately if the carrier files an objection.
How does the QME report affect my settlement?
The QME or AME report determines disputed medical-legal issues, including your permanent disability rating. That rating is calculated under the DIR schedule using the AMA Guides and sets the benefit amount under Cal. Lab. Code §4658. A higher impairment rating from the QME or AME typically means a higher settlement value. Apportionment conclusions in the report, which reduce the employer's liability for pre-existing conditions, can also be challenged if they are incorrect.
Do I need a lawyer to get a QME?
You do not legally need a lawyer to trigger the QME process. However, the rules governing written objections, panel strike deadlines, and the scope of the QME evaluation are complex. A misstep, including failing to strike the right physician from the panel or missing a procedural deadline, can affect the outcome of your claim. An experienced workers' comp attorney navigates this process routinely and at no upfront cost to you.
How long does the QME process take?
After the QME panel is issued and both sides have completed the 10-day strike period, the remaining doctor must be contacted for an appointment. The DWC has rules governing how quickly the evaluation must be scheduled, but realistically the full process from objection to final QME report can take several months depending on the evaluator's availability and the specialty involved. An attorney can monitor the timeline and push for compliance when delays occur.
