The first workers' comp clinic saw you for ten minutes. The doctor barely discussed your job, symptoms, or restrictions. The treatment plan is going nowhere, your work note does not match what you can safely do, or the office keeps losing records.
You want another doctor. The adjuster says you cannot switch. The clinic says you need approval. An online directory shows hundreds of names, but half of them may not treat your injury or accept new workers' comp patients.
Do not treat those answers as the final word.
California's medical provider network rules generally allow an injured worker covered by an MPN to select another physician inside the network after the first MPN visit. A different process applies when the worker specifically disputes the treating doctor's diagnosis or prescribed treatment and wants a formal second or third opinion.
A 2026 regulation change also added a records-transfer requirement that matters when treatment moves to a selected MPN physician.
This article provides general information, not medical or legal advice. The correct treatment path can depend on whether an MPN applies, whether notice was properly provided, the accepted body parts, emergency care, valid predesignation, claim status, network access, and the exact dispute. Do not stop treatment, medication, or work restrictions without appropriate medical guidance.
Start by Confirming Which MPN Actually Applies
A medical provider network, or MPN, is a group of medical providers established by an insurer or self-insured employer and approved by California's Division of Workers' Compensation to treat workplace injuries.
Before trying to change doctors, get the network information in writing:
- MPN name and identification number;
- claims administrator or insurer;
- MPN contact or designated representative;
- provider-directory website and search date;
- geographic search area;
- injury type or medical field needed;
- claim number and date of injury;
- current treating physician;
- written MPN notices provided to you;
- language-access instructions.
Do not assume the employer's health plan, an occupational clinic chain, and the workers' comp MPN are the same network. Save the actual notice and directory result used for your claim.
California Labor Code section 4616.3 requires notice of the MPN's existence, the right to change treating physicians within the network after the first visit, and the method for accessing the participating-provider list. The statute also says a notice failure does not automatically create a right to treat outside the network; the effect can depend on whether the failure resulted in a denial of medical care.
After the First MPN Visit, the Worker May Select Another MPN Physician
Title 8, section 9767.6 says that after the initial medical evaluation with an MPN physician, a covered employee may select a physician of the employee's choice from within the MPN.
The chosen provider should have a medical field or recognized ability suited to the injury or condition. That means the directory search should be tied to the actual medical need, not merely the nearest name on a list.
A practical written request should identify:
- that you completed the initial MPN evaluation;
- the physician you selected;
- provider address and phone number;
- why the provider's medical field fits the claimed injury;
- the date you notified the adjuster or designated MPN contact;
- whether the office confirmed that it accepts new MPN patients;
- requested appointment date;
- records that must follow the claim.
Keep proof of delivery. A phone call may start the conversation, but an email, portal message, fax confirmation, or letter can establish who was selected and when notice was given.
The 2026 Rule Adds a 20-Day Records Requirement
California amended Title 8, section 9767.6 effective April 1, 2026.
The new subsection (f) says the insurer or employer must deliver all relevant medical records relating to the claim to the initial primary treating MPN physician selected by the employee within 20 days after notice of that selected physician. The records include relevant diagnostic and laboratory results.
For a subsequently selected MPN physician, the rule says the insurer or employer must provide medical records and diagnostic or laboratory results that the provider considers relevant, upon request.
The rule also requires selected MPN physicians to receive the MPN identification number and contact or submission information for treatment-authorization requests and bills.
That distinction matters:
- the 20-day language expressly addresses the initial primary treating MPN physician selected by the employee;
- later selected MPN doctors may need to request records they consider relevant;
- the rule does not mean the worker should sit silently while an appointment approaches without records;
- the worker should still preserve personal copies and document missing-record problems.
If the new doctor's office says it has no records, ask in writing:
- what records are missing;
- whether the office requested them;
- when and where the request was sent;
- whether imaging was sent as actual images, reports, or both;
- whether work-status notes, RFAs, UR decisions, prescriptions, and referrals were included;
- whether the appointment or treatment plan is affected.
Do not recreate a missing report from memory. Ask for the original document and preserve the communication trail.
A Doctor Change Is Not Always a Second Opinion
An ordinary switch to another physician inside the MPN and a formal second-opinion request solve different problems.
A worker may want a routine change because of:
- poor communication;
- travel or scheduling problems;
- language access;
- repeated cancellations;
- lack of progress;
- a medical field that does not fit the injury;
- concern that the doctor is not accurately documenting symptoms or restrictions.
A second opinion under section 9767.7 applies when the worker disputes the treating physician's diagnosis or prescribed treatment.
Do not casually label every doctor switch a “second opinion.” The formal process carries specific steps, deadlines, record-transfer duties, and possible progression to a third opinion and MPN independent medical review.
How the MPN Second-Opinion Process Works
When disputing the diagnosis or treatment prescribed by the treating physician, section 9767.7 places responsibilities on both the worker and the employer or insurer.
The worker generally must:
- notify the designated MPN person that the treating physician's opinion is disputed and request a second opinion;
- select a physician from the available MPN list suited to the injury or condition;
- make the appointment within 60 days after receiving the provider list;
- inform the designated person of the appointment date.
The employer or insurer generally must:
- provide at least a regional list of available MPN physicians in the appropriate medical field;
- tell the worker about the right to request a copy of records sent to the second-opinion doctor;
- arrange for necessary medical records to reach that doctor before the appointment;
- provide the records to the worker upon request;
- notify the second-opinion doctor in writing about the selection and nature of the dispute, with a copy to the worker.
The regulation says failing to make the appointment within 60 days after receiving the list can waive the second-opinion process for that disputed diagnosis or treatment from that physician.
Save the date you received the list. A deadline measured from receipt becomes hard to prove when the envelope, email, or portal notice disappears.
Third Opinion and MPN Independent Medical Review
If the worker disagrees with the second physician's diagnosis or prescribed treatment, section 9767.7 allows a third opinion inside the MPN. The worker again must notify the designated person, select from the available list, make the appointment within 60 days, and report the appointment date.
Second- and third-opinion physicians issue written reports addressing the dispute and may offer alternative recommendations. The regulation provides for service of the report on the worker, designated MPN person, and treating physician within 20 days after the appointment or receipt of necessary diagnostic-test results, whichever is later.
If the worker still disputes the diagnosis or treatment after the third opinion, the regulation describes a possible request for MPN independent medical review, or MPN IMR.
MPN IMR is not the same as the independent medical review used to challenge a utilization-review decision. Similar acronyms are not interchangeable procedures.
Do Not Confuse the Treating Doctor with a QME
The primary treating physician manages treatment, work status, referrals, and medical reporting in the claim.
A Qualified Medical Evaluator, or QME, performs a medical-legal evaluation of disputed issues. A QME is not simply the worker's replacement treating doctor.
Changing the treating physician does not automatically:
- cancel a QME appointment;
- replace the QME process;
- overturn a utilization-review decision;
- approve treatment;
- change accepted body parts;
- resolve temporary disability or permanent disability disputes;
- erase earlier medical reports.
Our guide to QME report errors and missing issues explains the separate medical-legal record.
If the dispute concerns an RFA or a UR decision, read our guide to treatment authorization and RFA records. A new treating doctor may inherit the treatment problem; the switch itself does not necessarily decide medical necessity.
What to Save When You Change Doctors
Create one folder for the transition and save:
Network and selection records
- MPN notice;
- directory search results with date and filters;
- provider profile;
- confirmation the office accepts the MPN and new patients;
- written doctor-selection request;
- delivery proof;
- adjuster or MPN response;
- appointment confirmation.
Medical records
- initial clinic report;
- current treating reports;
- work-status slips;
- imaging reports and image-access instructions;
- laboratory results;
- medication list;
- referrals;
- RFAs and supporting reports;
- UR and IMR decisions;
- second- or third-opinion reports;
- QME or AME reports, if relevant.
Missing-record timeline
For each missing item, record:
- document name;
- service or report date;
- who holds it;
- who requested it;
- request date and method;
- follow-up dates;
- response;
- effect on the appointment, treatment, or restrictions.
Never add text to an old report or assemble pieces into what looks like an original medical document. Keep your index separate from the records themselves.
What If the Directory Is Wrong or No Appointment Is Available?
An MPN list is not useful if the listed doctors do not treat the condition, are no longer participating, cannot be reached, or will not offer an appointment within applicable access standards.
Document each contact:
- provider called;
- date and time;
- number used;
- whether the provider is still in the MPN;
- whether new workers' comp patients are accepted;
- medical field available;
- first appointment offered;
- language or accessibility needs;
- name of the person who responded.
Send the failed-search log to the designated MPN contact and ask for an available regional list suited to the injury. Do not simply disappear from authorized treatment or assume that one bad directory result automatically permits any outside doctor.
Frequently Asked Questions
Can the adjuster choose my doctor forever?
An MPN may control the network when validly applicable, but Labor Code section 4616.3 and Title 8 section 9767.6 recognize the worker's ability to change treating physicians within the MPN after the first visit. The facts and notices still matter.
Do I need the adjuster's permission to select another MPN doctor?
The rules describe selection within the MPN after the first visit, but the transition should be documented through the MPN or claims process so the provider, records, billing information, and authorization route are correct. Do not rely on an unrecorded conversation.
Does the 20-day rule apply every time I switch doctors?
Section 9767.6(f) uses 20-day language for delivery to the initial primary treating MPN physician selected by the employee after notice of the selection. For subsequently selected MPN physicians, it requires relevant records deemed necessary by that provider upon request. The exact timeline and facts should be reviewed carefully.
What if I disagree with the doctor's diagnosis?
A formal second opinion under section 9767.7 may apply. That process includes notice, an MPN list, a 60-day appointment deadline, record duties, and possible progression to a third opinion and MPN IMR.
Can the new doctor immediately approve surgery or therapy?
A treating physician can evaluate the worker and make recommendations, but treatment requests may still be subject to reporting, RFA, utilization-review, network, and other workers' compensation procedures. A doctor change is not automatic treatment approval.
