How Long Does a QME Have to Issue a Supplemental Report in California?
A California QME generally has 60 days from a party's written or electronic request to finish and send a supplemental report. That is a separate clock from the 30 day deadline for the first comprehensive report. Title 8 of the California Code of Regulations, section 38 sets both time frames, and the parties can agree in writing to one added extension of up to 30 days. A request that is really about fixing a factual error in the report follows a shorter, different timeline instead.

How long does a QME have to issue a supplemental report in California?
A QME generally has 60 days from a written or electronic request to complete a supplemental report. The parties can add up to 30 more days by agreement, for a top end of 90 days.
A Qualified Medical Evaluator, or QME, writes a report after your exam. Sometimes that report is not the end of the story. New records surface. A question goes unanswered. One side wants the same doctor to look again before the case moves forward.
That follow up request is a supplemental report. California sets its own deadline for it, separate from the 30 day deadline that applies to the first exam report. For the full timeline from the exam itself through that first report, see what happens after a QME exam in California.
This guide covers the supplemental report clock on its own: how long the doctor has, when the clock can stretch, and how a request to fix a factual error works on a different timeline.
What is a supplemental report, and who can ask for one?
Either side, the worker or the claims administrator, can ask the same evaluator in writing to address a new issue, review new records, or fill a gap left in the first report.
A supplemental report is not a new exam. Title 8 of the California Code of Regulations, section 31.7 describes it as a follow up evaluation or a supplemental evaluation from the same evaluator, used once a new medical dispute comes up after a report has already been issued. In practice, the doctor reviews what is sent and answers in writing, without seeing you again in person.
The request still has to follow the usual contact rules. Labor Code section 4062.3 requires any new records supporting the request to be served on the opposing party, and it bars private, one sided contact with the evaluator. Skip that step, and you can create a second dispute on top of the first one.
How many days does the QME have to send the supplemental report?
Sixty days from the date of the written or electronic request, under Title 8, section 38(i). The parties can agree, on their own, to one more 30 day extension, with no need to ask the Medical Director first.
This is the number most people searching this question want. Title 8 of the California Code of Regulations, section 38 states plainly that the time frame for a supplemental report "shall be no more than sixty (60) days from the date of a written or electronically transmitted request to the physician by a party."
That 60 day clock is not the same as the stricter 30 day deadline for the very first comprehensive report, which sits in section 38(a) and which our guide to what happens after a QME exam covers in full. Both deadlines live inside section 38, but they answer two different questions: one covers the first report, the other covers a later request sent back to the same doctor.
Section 38(i) lets the worker and the claims administrator agree between themselves to add up to 30 more days to that 60 day clock. Unlike an extension on the first report, this one skips the Medical Director entirely. Ninety days is the longest a properly extended supplemental report should take.
| Report | Deadline | How it can be extended | Source |
|---|---|---|---|
| First comprehensive report | 30 days from the exam | Medical Director approves up to 30 more days, or 15 for good cause | Title 8, section 38(a) and (c) |
| Supplemental report | 60 days from the written request | Both sides can agree to add up to 30 more days, no Medical Director needed | Title 8, section 38(i) |
| Factual correction response | 10 days if the worker asked, 15 days if the claims administrator or both did | Not extendable under this rule | Title 8, section 37 |
Does a different deadline apply if you are correcting a factual error instead?
Yes. A request to fix a factual error, rather than ask a new medical question, follows Title 8, section 37 instead, with its own 30 day request window and a 10 to 15 day response time.
Section 38(i) says its 60 day rule applies except as provided in section 37 for a request for factual correction. Section 37 covers a narrower problem: the report got a fact wrong, such as the wrong job duties, the wrong injury date, or a record the evaluator never actually reviewed.
An unrepresented worker has 30 days from receiving the report to ask for that kind of correction. The evaluator then has 10 days to answer if the worker filed the request, or 15 days if the claims administrator filed it, or if both sides did. The evaluator's answer is also called a supplemental report under the regulation, which is part of why the two requests get mixed up.
Picking the right request matters. A factual correction only fixes an actual error in the record. A broader disagreement with the evaluator's medical opinion is a different problem, covered in our guide to challenging a bad QME report.
What has to go with the request, and what happens if the deadline passes?
New records have to go with the request and be served on the other side at the same time. The regulation does not spell out an automatic new evaluator if that 60 day clock for a supplemental report runs out, the way it does for a late first report.
Labor Code section 4062.3 requires that any new records supporting a supplemental request be served on the opposing party, not sent to the doctor alone. Keep a dated copy of exactly what you sent.
For the very first comprehensive report, Title 8, section 38(b) lets either side ask for a whole new evaluator once that 30 day deadline passes without an approved extension. Section 38(i) does not repeat that specific remedy for a late supplemental report. If a supplemental request sits well past 60 or 90 days with no answer, raising it directly with the Division of Workers' Compensation Medical Unit is the next step, and a claim that is otherwise stuck can still move forward with a Declaration of Readiness to Proceed before the Workers' Compensation Appeals Board, or WCAB.
Why would a case need a supplemental report in the first place?
New medical records, a disputed issue the first report never squarely answered, or a question about future care are the usual reasons to send one.
Labor Code section 4062.3 expects a formal evaluation to address every contested medical issue in the claim, not only the single question that first triggered the panel. When treatment records turn up after the exam, or a question about apportionment or future care never got a clear answer, a supplemental request asks the same doctor to close that gap instead of starting over with a different evaluator.

Frequently Asked Questions
Is a supplemental report the same thing as a brand new QME exam?
No. A supplemental report is a desk review. The same evaluator reads new records or answers a specific question in writing without examining you again. Title 8, section 31.7 calls the in person version a follow up evaluation instead, and that one still follows the 30 day exam deadline, not the 60 day supplemental deadline.
Can the supplemental report deadline of 60 days be extended?
Yes. Title 8, section 38(i) lets the worker and the claims administrator agree in writing to add up to 30 more days, for a maximum of 90 days total. Unlike the first report, this extension does not need the Medical Director's sign off.
What if I am unrepresented and just need a factual error fixed?
That request follows Title 8, section 37, not the 60 day rule for a supplemental report. You have 30 days from receiving the report to ask for the correction, and the evaluator then has 10 days to respond, or 15 days if the claims administrator filed the request or both sides did.
Does this 60 day rule apply to an Agreed Medical Evaluator too?
Section 38 is titled to cover QMEs and AMEs together, and section 31.7 lists an Agreed Medical Evaluator among the evaluators who provide a follow up or supplemental evaluation. The 60 day supplemental clock applies the same way it does to a panel QME.
Does only the worker get to ask for a supplemental report?
No. Title 8, section 38(i) lets either party, the worker or the claims administrator, send the written or electronic request. The right to ask is not limited to one side.
What if the QME never responds to the supplemental request at all?
The regulation does not list an automatic replacement for a late supplemental report the way it does for a late first report. Contact the Division of Workers' Compensation Medical Unit directly, and if the claim is otherwise ready to move, a Declaration of Readiness to Proceed can bring it in front of a judge.
My QME report already came back unfavorable. Does a supplemental request fix that?
Sometimes, if the problem is a gap or a missing record. If the real issue is that you disagree with the evaluator's opinion itself, a supplemental request is only one of several tools; see our guide to challenging a bad QME report for the full set.
