Sending records and an advocacy letter to a panel QME: the 20-day and 10-day rules
Once the panel QME is selected, the next piece of work is the records packet: what the evaluator will read, the letter that frames the questions, and the service on the other side that makes both admissible. This guide covers the rules for represented California workers’ comp cases under Labor Code §4062.3 and 8 CCR §35, with a worked timeline and a checklist.
The short version
- Anything you want the QME to read must be served on the other side 20 days before it goes to the doctor (LC §4062.3(b)).
- The other side has 10 days to object to non-medical records. A timely objection keeps them out unless a judge orders otherwise. Medical records cannot be blocked by objection.
- The advocacy letter, and any other pre-exam communication, is served on the other side 20 days before the evaluation (LC §4062.3(e)).
- Put an index at the front of the records, in order (8 CCR §35(c)). Copy every party on everything (8 CCR §35(g)).
- A communication the other side did not get is ex parte: the aggrieved party can take a new QME and recover the costs (LC §4062.3(g), (h)).
Abbreviations: QME (Qualified Medical Evaluator), AME (Agreed Medical Evaluator), AA (applicant attorney), DA (defense attorney), POS (proof of service), WCJ (workers’ compensation judge), WCAB (Workers’ Compensation Appeals Board), LC (Labor Code), CCR (California Code of Regulations, Title 8).
1. Two different 20-day clocks
The statute sets two 20-day rules that are easy to run together. One is measured to the day the records reach the evaluator, the other to the day of the exam:
Records and other information
Serve on the opposing party at least 20 days before the day they are sent to the evaluator. The clock is measured to the day the package goes to the doctor, not to the exam.
LC §4062.3(b); 8 CCR §35(c)
The cover or advocacy letter, and any other pre-exam communication
In writing, served on the opposing party at least 20 days before the evaluation. Measured to the exam date.
LC §4062.3(e)
Objection to non-medical records
The opposing party has 10 days after service to object. A timely objection keeps those records from the evaluator unless a WCJ orders otherwise.
LC §4062.3(b); 8 CCR §35(d)
Communications after the evaluation
In writing, served on the opposing party when sent to the evaluator.
LC §4062.3(e)
Because the objection window on non-medical records is 10 days, plus 5 when served by mail, fax or email to a California address (8 CCR §10605), serving the package 35 days before the exam lets the window close before the records have to leave for the doctor. The timeline below uses that spacing.
2. What may go to the QME
LC §4062.3(a) and 8 CCR §35(a) describe what either party may provide:
- Records prepared or maintained by the employee’s treating physician or physicians.
- Other medical records relevant to the disputed issue, including prior treatment records.
- A letter outlining the treating physician’s determination or the compensability issues the evaluator is asked to address (8 CCR §35(a)(3)).
- Non-medical records, including films and videotapes, once the 20-day service and 10-day objection process in §35(c) and (d) has run.
What may never go
8 CCR §35(e) bars three things from the packet no matter who sends it: a medical-legal report that was rejected as untimely under LC §4062.5; a report by a physician who is neither a treater nor an evaluator in the case, on permanent impairment, permanent disability or apportionment, unless a WCJ first ruled it admissible; and anything a WCJ has stricken or found inadmissible.
3. The 10-day objection
The objection right in LC §4062.3(b) is limited to non-medical records: “If the opposing party objects to consideration of nonmedical records within 10 days thereafter, the records shall not be provided to the evaluator.” 8 CCR §35(d) adds that a WCJ can order them provided anyway. Either party may use discovery to establish the accuracy or authenticity of a non-medical record before the evaluation.
There is no parallel objection right for medical records. A party who believes a medical record should not reach the QME, for example a report that §35(e) forbids, raises it with the other side and, if needed, the WCJ. The 20-day service period exists so that can happen before the doctor has read it.
When the claims administrator serves records on an unrepresented employee, §35(c) requires a conspicuous notice beginning “Please look carefully at the enclosed information” and telling the employee to object within 10 days. In a represented case the parties serve each other through counsel.
4. The index
8 CCR §35(c) requires the claims administrator to attach a log to the front of the records that identifies each item and lists them in the order attached, and requires the applicant attorney’s office to do the same for anything it sends to the evaluator directly. In practice both sides call it the index. It serves two purposes: the evaluator must identify in the report all information received, reviewed and relied on (LC §4062.3(d)), and if a record is later said to be missing or added, the index and the POS show what was served and when.
§35(g) closes the loop: copies of all records sent to the evaluator go to all parties, and a failure to copy a party “shall constitute ex parte communication” by the sender.
5. The advocacy letter
The WCAB’s en banc decision in Maxham v. California Department of Corrections and Rehabilitation (2017) 82 Cal.Comp.Cases 136 drew the line between “information” and a “communication” under LC §4062.3. Records, and anything that contains, references or encloses them, are information and follow the records rules above. A letter that describes the mechanism of injury, the body parts claimed, each side’s contentions and the questions the evaluator is asked to answer is a communication: it may be sent, in writing, with service on the other side 20 days before the evaluation under LC §4062.3(e).
- Fine: dates of injury and employment, the mechanism, admitted and denied body parts, the firm’s position and the carrier’s stated position, the standard questions (causation, AOE/COE, MMI, impairment under the AMA Guides, apportionment under LC §§4663 and 4664, work restrictions, future medical).
- Not fine: quoting or summarizing a medical record that has not gone through the 20-day process, attaching records to the letter, misstating the record or the law, or telling the doctor what to conclude. Any of these turns the letter into information, or into a ground to strike it.
A party who receives a letter it believes crosses the line should object in writing right away and, if the letter goes to the evaluator anyway, ask the WCJ to strike it or the report. The safest schedule is to serve the proposed letter on the other side together with the records package, so any dispute is resolved before the 20-day mark.
6. Ex parte communication
LC §4062.3(g) prohibits ex parte communication with a panel QME or an AME. The remedy belongs to the aggrieved party: terminate the evaluation and obtain a new QME under LC §4062.2, or proceed with the original evaluator. 8 CCR §35(k) has the Medical Director issue the new panel. Under LC §4062.3(h) the party that made the communication may be charged with contempt before the WCAB and is liable for the costs it caused, including the cost of the evaluation, additional discovery costs and attorney’s fees for related discovery.
What is not ex parte
- Oral or written contact with the evaluator’s staff on nonsubstantial matters: scheduling, a missed appointment, furnishing records and reports, whether the report is ready (LC §4062.3(f); 8 CCR §35(b)(1)). Put anything that matters in writing with a copy to the other side anyway.
- What the employee says to the evaluator during the examination, or at the evaluator’s request in connection with it (LC §4062.3(i)).
- The evaluator consulting the treating physician, which §35(j) allows; the evaluator must note any new information received.
7. Records that arrive late
Under 8 CCR §35(i), if a party fails to provide relevant records within 10 days after the evaluation, the evaluator still issues the report within the §38 time limits and notes that the records were not received. A supplemental evaluation follows on request once the records arrive. Under §38(h) the evaluator cannot get an extension because records are missing. Under §38(i) a supplemental report is due within 60 days of a written request, the parties may agree to 30 more days, and new records sent with the request must have been served on the other side under LC §4062.3 first.
8. A worked timeline
The applicant attorney wants the QME to read the treating records, two MRI reports, and a job description, and to receive an advocacy letter. The exam is Thursday, May 13, 2027.
- Thu, Apr 8, 2027Applicant attorney serves the proposed records package, its index, and the draft advocacy letter on defense counsel with a proof of service. This is 35 days before the exam: 20 days for the records rule plus 15 for the mailed objection window.
- Fri, Apr 23, 2027Defense’s window to object to any non-medical record closes: 10 days from service plus 5 for mail under 8 CCR §10605. No objection has arrived. The same day, AA sends the package and the letter to the QME, with a copy to defense, and serves a POS. This is exactly 20 days before the exam, so both 20-day rules are met.
- Mon, May 3, 2027Defense serves its own records on AA. They cannot go to the QME before Sun, May 23, which is after the exam; the QME will see them, if at all, as a post-exam supplement with a record of when they arrived (8 CCR §35(i)).
- Thu, May 13, 2027Evaluation. From here on, anything sent to the QME is copied to the other side the same day.
- Sat, Jun 12, 2027Day 30: the report is due unless the QME has asked the Medical Director for an extension at least 5 days before this date (8 CCR §38(a), (c), (d)).
Dates chosen to avoid court holidays. The 30-day report date falls on a Saturday; the report is the evaluator’s deadline, not a filing, so no roll-over rule applies to it.
9. Packet checklist
- Cover letter to the QME that lists every enclosed item. LC §4062.3(d) requires the evaluator to identify all information received, reviewed and relied on; a complete list makes the report’s recital match what you sent.
- Index (log) at the front of the records, in the order the records are attached. 8 CCR §35(c) requires the claims administrator to attach one, and the applicant attorney’s office to do the same for anything it sends directly.
- Treating physician records and reports, then other medical records, then prior medical-legal reports. The categories LC §4062.3(a) and 8 CCR §35(a) allow. Leave out anything 8 CCR §35(e) forbids: a report rejected as untimely under LC §4062.5, a non-treating, non-evaluator report on impairment or apportionment that no WCJ has admitted, and anything a WCJ has stricken.
- Non-medical records (job descriptions, incident reports, films, surveillance), each with the POS showing when it was served on the other side. These are the records the other side can block within 10 days; the POS proves the window has closed.
- The advocacy letter, served on the other side 20 days before the exam. LC §4062.3(e). Keep it to mechanism of injury, body parts, each side’s contentions and the questions; see Maxham below.
- Proof of service on the opposing party for the package and for the letter. A copy that does not reach every party is an ex parte communication by the sender (8 CCR §35(g)).
- Calendar entries: the objection window, the send-to-QME date, the exam, day 30 for the report. The dates move together; see the worked timeline.
How Amber handles this
Amber is an AI agent for California workers’ comp firms. It reads the case’s documents and email as they arrive, so by the time a QME is selected it already knows which treating records, diagnostics and prior reports exist. For the packet it:
- Assembles the records in order and writes the index, flagging anything that falls under 8 CCR §35(e).
- Drafts the advocacy letter from the firm’s template, with the mechanism, body parts, contentions and questions filled in from the file and no record quoted that has not been served.
- Drafts the proofs of service and the email to defense counsel, and calendars the objection window, the send date, the exam and the day-30 report date together.
- Leaves everything as a draft for attorney review. Nothing is served until the attorney approves it.
Questions
How far in advance must records be served on the other side before they go to a panel QME?
Twenty days. Labor Code section 4062.3(b) says information a party proposes to provide to a panel QME "shall be served on the opposing party 20 days before the information is provided to the evaluator." 8 CCR section 35(c) repeats the rule. The 20 days run from service on the other side to the day the records go to the doctor, not to the exam date.
Can the other side block records from reaching the QME?
Only non-medical records. Under Labor Code section 4062.3(b), if the opposing party objects to non-medical records within 10 days after service, those records are not provided to the evaluator unless a workers’ compensation judge orders otherwise. There is no objection right in the statute for medical records; a dispute about a medical record goes to the judge.
Does the advocacy letter have to be served on the other side?
Yes, and early. Labor Code section 4062.3(e) requires that all communications with a panel QME before the evaluation be in writing and served on the opposing party 20 days in advance of the evaluation. After the evaluation, a communication is served on the other side when it is sent to the evaluator.
What may an advocacy letter to a QME say?
Under the WCAB’s en banc decision in Maxham v. California Department of Corrections and Rehabilitation (2017) 82 Cal.Comp.Cases 136, a letter that describes the mechanism of injury, the body parts claimed, each side’s contentions and the questions the evaluator is asked to answer is a "communication" that may be sent on 20 days’ notice. It becomes "information," subject to the records rules, when it contains, references or encloses medical or non-medical records, or misrepresents facts or law.
What is the penalty for an ex parte communication with a QME?
Under Labor Code section 4062.3(g) and (h), the aggrieved party may terminate the evaluation and obtain a new QME, or proceed with the original evaluator. The party that made the communication may be charged with contempt and is liable for the costs it caused, including the cost of the evaluation, additional discovery costs and related attorney’s fees. 8 CCR section 35(k) directs the Medical Director to issue a new panel to the aggrieved party.
What happens if records reach the QME after the exam?
Under 8 CCR section 35(i), if relevant records are not provided within 10 days after the evaluation, the evaluator still issues the report on time and notes that the records were not received. A supplemental report can be requested once the records arrive. Under 8 CCR section 38(i), a supplemental report is due within 60 days of the written request, and new records sent with the request must have been served on the other side under Labor Code section 4062.3.
