California DEU Consultative Ratings: Settlement Guidance and Trial Evidence

A DEU consultative rating can help evaluate a settlement, but it cannot serve as trial evidence. California’s rule expressly makes that type of rating inadmissible in judicial proceedings. Before treating a permanent disability percentage as the answer to your claim, identify which kind of rating you have, which medical reports it used, and whether the disputed issues require a formal rating and findings.

Identify the rating before relying on the percentage

The Disability Evaluation Unit (DEU) performs different tasks. A consultative rating is an advisory calculation requested for purposes such as assessing ratable factors, settlement adequacy, commuted values, and occupational questions. Under California Code of Regulations, title 8, section 10166(b), consultative rating determinations are not admissible in judicial proceedings.

That distinction matters even when a document looks official and bears a precise percentage. The calculation does not establish that the physician selected the correct impairment, that all claimed conditions were addressed, or that the judge can adopt the result at trial. A percentage is the output of particular inputs; changing the medical report, occupation, age, or legal assumptions can change the result.

A consultative rating also cannot substitute for a summary rating, which has a separate determination and review process. If your problem concerns a summary rating and its review procedure, see our DEU summary rating reconsideration checklist. First confirm the document’s heading and procedural role rather than applying the deadline for one type of rating to another.

Check who requested it and why

Section 10166 permits reasonable requests from employers, injured workers, and their representatives. It places limits on an insurer’s request to terminate liability or negotiate a compromise and release with an unrepresented worker. Once an application for adjudication has been filed, a consultative rating requires prior written authorization from a workers’ compensation judge, arbitrator, or Information and Assistance officer. These safeguards are separate from the question whether the result can be used at trial.

Keep the request, authorization, rating, and medical reports together. Identify your occupation and age at the time of injury, which the requesting person must provide. If the papers contain a job classification you do not recognize, document your actual duties and raise the discrepancy before relying on the calculation.

Compare the inputs when percentages disagree

Create a short record of each proposed percentage. For every rating, record the date, author, medical report dates, body parts, whole person impairment findings, occupation and age, and any apportionment or excluded psychiatric component. Preserve the complete underlying reports, including supplements and deposition testimony; a benefit notice alone may not show the reasoning.

In Ramirez v. Quality Scales Unlimited, the record contained a 40% consultative rating and notices referring to 58% and 65%. Those were not three interchangeable evaluations of an identical medical record. The WCAB panel identified different report dates and an unexplained choice of the 40% figure. It did not award the higher percentage simply because it appeared in another document.

This is why a useful comparison identifies a disagreement’s source. Is a later report missing? Did the rating omit a claimed impairment? Did the doctor explain the selected impairment and the effect of a prior injury? Those questions can reveal a medical or legal dispute that a calculator cannot resolve.

Prepare the evidence that a contested decision needs

A medical opinion must explain its findings sufficiently to support the disability determination. The WCJ must assess the evidence and explain the decision. In Ramirez, the panel explained that a judge uncertain about the calculation could provide formal rating instructions to the DEU after reviewing the medical evidence; the judge could not hand off the underlying impairment assessment to the rater.

Our analysis of Blackledge and the physician, judge, and rater’s respective roles explains that division of responsibility. Formal rating assistance does not repair an unexplained medical opinion, settle contested facts, or make an advisory consultative rating admissible.

For trial preparation, organize the admitted or proposed medical evidence, the issues that remain disputed, and the findings necessary to resolve them. A request to clarify a medical report, a formal rating process, and a challenge to an existing award are different procedural steps. Determine which step your case actually requires before submitting a document.

Questions to take to a consultation

• Is this a consultative, summary, or formal rating?
• Which medical reports and impairment findings produced this percentage?
• Do the report dates match the latest evidence in my case?
• Are disputed body parts, psychiatric impairment, or apportionment unresolved?
• What authorization, evidence, or rating instructions does the present stage require?

Bring the rating and complete medical record to an Information and Assistance officer or your representative. Mishra X Trial Lawyers’ Irvine office can review California workers’ compensation rating disputes. A productive review starts with the kind of document and the evidence behind its number.
