Medical Chronologies for QME and AME Evaluators: What Makes a Chronology Report-Ready – Copy
California law already anticipates that someone other than the evaluator will organize the records. It is specific about what that person may do, and about what the physician still has to do afterward.
Table of Contents
The short version
- Labor Code 4628(c) expressly contemplates a third party preparing the initial outline or excerpting of records.
- The same statute requires the physician to review the excerpts, the entire outline, and to go further as needed.
- A chronology that cannot be checked against the source records is worse than none, because verification is the physician’s obligation.
- Non-compliance under 4628(e) costs the report and the fee.
Most discussion of medical chronologies in the medical-legal context treats them as a convenience. The statute treats them as a defined step in report preparation, with conditions attached. Those conditions are what separate a chronology an evaluator can build a report on from one that quietly creates exposure.
What Labor Code 4628 lets someone else prepare
Labor Code 4628(a) provides that no person other than the physician who signs the report, except a nurse performing functions routinely performed by a nurse, shall examine the injured employee or participate in the nonclerical preparation of the report. Reviewing and summarizing prior medical records is named as part of that nonclerical preparation, alongside taking the history and drafting the report’s conclusions.
Subdivision (c) then carves out the practical exception. Where the initial outline of the patient’s history or the excerpting of prior medical records is not done by the physician, the physician shall review the excerpts and the entire outline, and shall make additional inquiries and examinations as are necessary and appropriate to identify and determine the relevant medical issues.
| Task | Who may perform it |
|---|---|
| Examining the injured employee | The signing physician, and a nurse for routine nursing functions |
| Taking the complete history | The signing physician |
| Drafting the report’s conclusions | The signing physician |
| Initial outline of the history | May be prepared by another, subject to physician review of the entire outline |
| Excerpting prior medical records | May be prepared by another, subject to physician review of the excerpts |
| Reviewing and summarizing prior records for the report | The signing physician |
| Transcription and clerical production | Clerical staff; exempt from the (b) disclosure requirement |
| Disclosing who performed any non-clerical service | Required in the report under 4628(b), with qualifications stated |
The California Orthopaedic Association’s report guidance states the consequence in blunt terms: a QME cannot comply with the relevant portions of the Labor Code and Title 8 by reviewing only a summary of records, and a summary prepared by one of the parties or their attorney cannot be relied upon. The physician must actually review the available records.
That is not an argument against chronologies. It is a specification for them. A chronology’s function is to make the physician’s own review faster, more complete, and easier to cite. Any chronology sold or built on the premise that the physician need not read the underlying records is selling a compliance problem.
What a 4628 violation costs: admissibility, fees, and QME status
Failure to comply with the requirements of Labor Code 4628 makes the report inadmissible as evidence and eliminates any liability for payment of any medical-legal expense incurred in connection with it.
——- Labor Code 4628(e), paraphrased
That is the floor rather than the ceiling. A knowing failure carries a civil penalty of up to $1,000 for each violation under subdivision (f), assessed by a workers’ compensation judge or the Appeals Board. Under (g), a physician assessed that penalty may be terminated, suspended, or placed on probation as a qualified medical evaluator pursuant to Labor Code 139.2(k) and (l). Subdivision (h) makes a knowing failure subject to contempt under the Board’s judicial powers.
By contrast, 8 CCR 10606 requires medical-legal reports to comply with 4628, and provides that failure to meet 10606’s own requirements does not make a report inadmissible but will be considered in weighing the evidence. That is why 4628 is the harder floor.
The report must disclose who prepared the chronology
Subdivision (b) is the provision most often left out of this discussion. The report shall disclose the name and qualifications of each person who performed any services in connection with the report, including diagnostic studies, other than its clerical preparation.
Preparing an initial outline or excerpting records under (c) is a service performed in connection with the report, and (a)(2) classes record review and summary as nonclerical. On that reading, where a chronology is prepared by someone other than the physician, the report discloses who prepared it and their qualifications. Subdivision (j) points the same way, because the mandatory perjury declaration is written to accommodate received information:
The physician declares the report true and correct to the best of their knowledge and belief, except as to information the physician has indicated was received from others. As to that information, the physician declares it accurately describes the information provided to them and, except as noted, that they believe it to be true.
— Labor Code 4628(j), paraphrased from the statutory declaration
The declaration assumes some content came from elsewhere, requires the physician to indicate which, and holds them to attesting it accurately describes what was provided. A chronology therefore needs two things beyond its contents: the preparer’s name and qualifications, and enough traceability that the physician can honestly make that attestation. A vendor who cannot supply a named preparer is handing the evaluator a disclosure question under (b) and an attestation question under (j).
What makes a QME chronology report-ready
If the physician’s obligation is to review the excerpts, the entire outline, and the records, then the most useful property of a chronology is that every line can be traced back to a page. Most of what makes a chronology unusable follows from that.
| Requirement | Why it matters | What breaks it |
|---|---|---|
| Source pagination preserved | The physician verifies entries against the record set and cites them in the report | Renumbering, re-collating, dropping original page references |
| Page count intact and countable | Review beyond the base threshold is billed per page and verified under penalty of perjury | Condensing source pages onto one, or excluding duplicates without noting them |
| Every entry dated and attributed to a provider | 8 CCR 10606 requires the source of the facts stated in the history | Undated summaries, merged provider narratives |
| Conditions and body parts tracked separately | Apportionment and causation are analyzed per body part | A single chronological stream with no condition tagging |
| Non-industrial events flagged, not buried | Prior and intervening causes drive apportionment | Treating all entries as equivalent |
| Treatment gaps named as gaps, with the interval stated | A missing interval is a finding, not an absence | Silent omission, which reads as no treatment |
| Diagnostic studies listed with date, body part, and findings as recorded | The evaluator cites imaging and testing directly | Characterizing findings rather than reproducing them |
| No conclusions or opinions embedded | Conclusions are reserved to the physician under 4628(a) | Interpretive language, characterizations, advocacy framing |
| Preparer’s name and qualifications supplied | The physician makes the disclosure required by 4628(b) | Anonymous or white-labeled work product |
| Deliverable in a form servable on the opposing party without revision | It travels with the record package under 4062.3 | Anything written as internal work product |
A working specification. Each row is a property the evaluator needs, and the practice that defeats it.
The eighth row is the one most often gotten wrong. A chronology that characterizes the records has begun drafting conclusions, which the statute reserves to the signing physician. Neutral, dated, attributed entries are not a stylistic preference here.
Record review page counts under the medical-legal fee schedule
Under 8 CCR 9795, effective April 1, 2021, the base evaluation codes include a fixed allowance of record review, and everything beyond it is billed under MLPRR at $3.00 per page.
| Code | Evaluation type | Fee | Pages included |
|---|---|---|---|
| ML201 | Comprehensive medical-legal evaluation | $2,015 | 200 |
| ML202 | Follow-up evaluation, pages not previously reviewed | $1,316.25 | 200 |
| ML203 | Supplemental evaluation | $650 | 50 |
| MLPRR | Each page beyond the threshold | $3.00 per page | — |
A page is an 8.5 by 11 inch single-sided document, chart, or paper, in physical or electronic form, and multiple condensed pages displayed on a single page are charged separately. Four condensed deposition pages on one sheet count as four. Records must arrive with a declaration under penalty of perjury under Labor Code 4062.3 stating the page count, and a physician cannot bill for reviewing documents that lack it.
One limitation deserves attention, because it puts the initial record set at the center of the evaluator’s economics. Under ML203, fees are not allowed for a supplemental report following review of information that was already available in the physician’s office or included in the medical record provided before the comprehensive report. An incomplete initial set cannot be cured later by a billable supplemental if the material was already in the file. Completeness at the front end protects the fee as well as the opinion.
A chronology that re-collates a record set, strips original pagination, or silently removes duplicates leaves the evaluator unable to verify a page count they are attesting to under oath. On files running into four figures, that is not a rounding error.
Substantial evidence and the incomplete record set
Substantial evidence is relevant evidence that a reasonable mind might accept as adequate to support a conclusion, under Braewood Convalescent Hospital v. Workers’ Comp. Appeals Bd. (1983) 34 Cal.3d 159. Labor Code 4628 and 8 CCR 10606 supply the essential elements, including a complete history, a review and summary of prior relevant records, and the source of the facts stated in the history.
A recent panel decision shows how directly an inadequate history disposes of an opinion. In ADJ18384896, decided January 2026, a treating physician assigned apportionment to earlier injuries without reviewing any records from the claimant’s prior cumulative trauma claim. The Board reasoned the opinion was not based on an adequate history, that this rendered it not substantial medical evidence, and that the fact alone made further analysis unnecessary. The competing evaluator, who had worked through 53 documents including two deposition transcripts spanning roughly eight years, was credited.
Panel decisions are persuasive rather than binding. The mechanism is ordinary nonetheless: an expert opinion is only as admissible as the record behind it.
Ordering a chronology: service rules under Labor Code 4062.3
A chronology prepared at a party’s direction and sent to the evaluator is information provided to the evaluator. Labor Code 4062.3 requires that information provided to a panel QME be served on the opposing party, that pre-evaluation communications be in writing and served at least 20 days before the evaluation, and that subsequent communications be served at the time they are sent.
Treating a chronology as internal work product and forwarding it with the records creates an avoidable problem. It travels with the record package, it needs the 4062.3 declaration, and it should read as something you are content for the other side and the judge to see. A neutral, dated, cited chronology satisfies that test. A characterized one does not. The same discipline is what makes the document useful for apportionment analysis later, and why exam preparation on the applicant side works from the same source material.
AB 1293, the QME report template, and public report quality
AB 1293 added Labor Code 4062.4, directing the Administrative Director to develop and make available a medical evaluation request form for communicating with a panel QME and a template QME medical-legal report form. The statutory deadline is January 1, 2027.
What exists today is guidance rather than mandate. The DWC QME page hosts a Medical Legal Quality Assurance Checklist and a separate Psyche Report Quality Assurance Checklist, each carrying the same note: a tool to help physicians develop their report, and not a required format or template. Neither is the AB 1293 form, and the statutory template had not appeared when this was written.
Report quality is already being examined, though, and not only prospectively. QMEs seeking reappointment must submit their two most recent medical-legal reports involving a face-to-face evaluation where the worker reached maximum medical improvement, through DWC’s online portal, or a statement of explanation if none exist. RAND’s study of qualified medical evaluators and the medical-legal process took report quality and methods of improving accuracy as central questions. Structure and completeness are moving from individual practice toward something measured, sampled, and published.
Why record volume makes this a workflow problem
On a long cumulative trauma or multi-body-part claim, the evaluator receives records from several providers across years, in no order, frequently duplicated, and often with the clinically decisive documents in the middle. The evaluator still has to read them. What a chronology changes is how long that takes and how reliably the physician can find, verify, and cite what matters. That is the whole value, and it is a substantial one.
Rapid Care MRR’s record review platform builds chronologies to the specification above: dated and attributed entries with source page references, conditions separated, duplicates identified rather than dropped, gaps flagged, and no interpretive language. We also maintain a note on the AB 1293 template and the record set behind it, since a standardized report form does nothing about the quality of what arrives for review.
The statute already says what a chronology is for. It is the initial outline, prepared so the physician’s own review is thorough and provable.
Send us one record set from an upcoming evaluation. We will return a chronology built to the specification above, at no cost on your first case, with source page references intact so you can verify every entry against the file as served, and with the preparer’s name and qualifications stated for your 4628(b) disclosure. Request a chronology. Files are handled under our HIPAA compliance program and returned or destroyed on request.
Frequently Asked Questions
Can a QME rely on a medical chronology prepared by someone else?
As an initial outline, yes. As a substitute for reviewing the records, no. Labor Code 4628(a) reserves nonclerical preparation of the report, including reviewing and summarizing prior records, to the signing physician. Section 4628(c) provides that where the initial outline or the excerpting of records is not done by the physician, the physician shall review the excerpts and the entire outline and make additional inquiries and examinations as necessary. California Orthopaedic Association guidance states that a QME cannot comply by reviewing only a summary of records, and that a summary from a party or their attorney cannot be relied upon.
What happens if a medical-legal report does not comply with Labor Code 4628?
Under 4628(e), the report is inadmissible as evidence and no medical-legal expense incurred in connection with it is payable. By contrast, 8 CCR 10606 requires compliance with 4628, and provides that failure to meet 10606’s own requirements does not render a report inadmissible but will be considered in weighing the evidence.
How many pages of record review are included in a QME evaluation fee?
Under 8 CCR 9795(c), effective April 1, 2021, ML201 ($2,015) and ML202 ($1,316.25) each include up to 200 pages of record review, and ML203 ($650) includes 50. Pages beyond the threshold are billed under MLPRR at $3.00 per page, and modifiers do not apply to per-page charges. A page is an 8.5 by 11 inch single-sided document in physical or electronic form, and condensed pages displayed on one page count separately. Records must arrive with a declaration under penalty of perjury under Labor Code 4062.3 stating the page count, and a physician cannot bill for reviewing documents that lack it. Each code also requires the report to verify the total pages reviewed under penalty of perjury.
Does a chronology sent to a QME have to be served on the opposing party?
Labor Code 4062.3 requires information provided to a panel QME to be served on the opposing party, with pre-evaluation communications in writing and served at least 20 days ahead, and subsequent communications served when sent. A chronology prepared at a party’s direction and forwarded to the evaluator is information provided to the evaluator, so the service and declaration requirements apply to it.
What makes a medical-legal report substantial evidence?
Relevant evidence that a reasonable mind might accept as adequate to support a conclusion, under Braewood Convalescent Hospital v. WCAB (1983) 34 Cal.3d 159, with the essential elements set out in Labor Code 4628 and 8 CCR 10606. An opinion resting on an incomplete history is exposed. In ADJ18384896, a January 2026 panel decision, a treating physician’s apportionment opinion was held not to be substantial medical evidence because he had reviewed no records from the prior cumulative trauma claim.
Is there a required QME report template in California?
Not yet. AB 1293 added Labor Code 4062.4, directing the Administrative Director to develop a medical evaluation request form and a template QME medical-legal report form, with a deadline of January 1, 2027. The DWC QME page currently hosts a Medical Legal Quality Assurance Checklist and a Psyche Report Quality Assurance Checklist, both expressly described as tools rather than a required format or template, plus a checklist tool embedded in a report-writing course. The California Orthopaedic Association also publishes a template DWC does not mandate. Confirm current status on the DWC QME page before relying on any of them.
Does the report have to disclose who prepared the medical chronology?
Labor Code 4628(b) requires the report to disclose the name and qualifications of each person who performed any services in connection with the report, other than its clerical preparation. Because 4628(a)(2) classes reviewing and summarizing prior medical records as nonclerical, an initial outline or excerpting prepared under 4628(c) is most naturally read as a disclosable service. The mandatory declaration in 4628(j) points the same way, since it requires the physician to indicate which information was received from others and to attest that it accurately describes what was provided. Evaluators should expect a chronology to arrive with a named preparer and stated qualifications.
What penalties apply for a Labor Code 4628 violation?
Under 4628(e) the report is inadmissible and no medical-legal expense connected with it is payable. A knowing failure to comply adds a civil penalty of up to $1,000 per violation under 4628(f), assessed by a workers’ compensation judge or the Appeals Board. Under 4628(g), a physician assessed that penalty may be terminated, suspended, or placed on probation as a QME pursuant to Labor Code 139.2(k) and (l), and 4628(h) makes a knowing failure subject to contempt under the Board’s judicial powers.
The Bottom Line
Speed-only medical record review saves time but costs accuracy, and the cost lands on the reserve line first. Accuracy-first review requires a different process, one that treats every complex file as a potential reserve error waiting to be caught rather than a box to be checked. When TPAs ask vendors only about turnaround time and cost per page, they are selecting for volume. On medical record review, the reserve line rewards them for selecting for accuracy.
