What Happens When a QME Disagrees With the Treating Physician?
A QME does not overrule a treating physician simply by issuing a different opinion. Both reports become evidence, and the stronger one is the one whose reasoning survives closer examination.
Disagreement between a Qualified Medical Evaluator and a treating physician is common enough to be built into the structure of California workers’ compensation.
The treating physician may believe an injured worker still requires restrictions, additional care, or more time before reaching maximum medical improvement. The QME may review the same case and reach a different conclusion about causation, disability, apportionment, or work capacity.
For the injured worker, the difference can be confusing. Both opinions came from physicians. Both may cite the medical record. Both may sound confident.
For the claims administrator and attorneys, the disagreement creates a different problem: which opinion better explains the medical evidence and the disputed issue?
The medical reports become part of the evidence in the case, and the strength of each opinion depends heavily on how it was reached and how well it is supported.
Why QME and treating physician opinions differ
The two physicians enter the case from different positions.
A treating physician is responsible for the injured worker’s ongoing medical care. They may see the patient repeatedly over months or years, observe how symptoms change, evaluate the response to treatment, and adjust restrictions as recovery progresses.
A QME has a different assignment.
The evaluator is brought into the workers’ compensation process to address a medical dispute. California DWC specifically identifies disagreements concerning issues such as the nature of the injury, work restrictions, temporary disability status, permanent disability, and future medical needs as reasons a QME evaluation may be requested.
The QME may see the injured worker only once, but often receives a broader set of records assembled for the dispute.
That can include:
- Treating physician reports
- Prior medical records
- Diagnostic imaging
- Previous injuries or claims
- Deposition testimony
- Job descriptions
- Medical-legal reports
- Records from other specialties
- Correspondence identifying the disputed issues
The physicians may therefore be looking at the same person through different lenses.
The treating physician has something the QME cannot recreate
Repeated treatment provides longitudinal context.
A physician who has seen the injured worker twelve times may know that symptoms initially improved, then returned after an attempted return to work. They may have observed changes in range of motion or strength over several visits. They know which treatments helped, which failed, and how the patient functioned throughout recovery.
That history can be valuable.
A one-time QME examination gives the evaluator a snapshot. Some conditions fluctuate. Pain may be worse on certain days. Neurologic symptoms may appear intermittently. Functional limitations observed over six months may not be obvious during a single appointment.
The treating record therefore deserves serious consideration.
A QME report becomes weaker when it dismisses months of treatment simply because the findings on one examination were different.
The QME may have information the treating physician never saw
The reverse can also happen.
A treating physician may only receive the records directly relevant to treatment. The QME may be given years of earlier medical history.
That additional evidence can materially change how the case looks.
Consider a worker being treated for persistent shoulder pain after an industrial injury. The treating physician may reasonably connect the symptoms to the work event based on the history available.
The QME later receives records showing:
- A previous shoulder injury
- Similar complaints two years earlier
- An MRI documenting preexisting pathology
- Prior physical therapy
- Earlier work restrictions
The existence of those records does not automatically disprove the industrial injury. They do create questions about baseline condition, causation, and apportionment that the treating physician may never have been asked to address.
This is one reason disagreements between physicians should be examined through the evidence each physician actually had.
A difference in diagnosis may only be the beginning
Sometimes the disagreement is obvious.
One physician diagnoses a lumbar strain while another believes the symptoms are primarily related to degenerative disc disease.
Many disagreements are less direct.
The physicians may agree on the diagnosis and disagree on:
- Whether work caused the condition
- Whether work aggravated a preexisting condition
- Whether the worker is temporarily disabled
- Whether restrictions remain necessary
- Whether the condition has become permanent and stationary
- The degree of permanent impairment
- The need for future medical care
- How disability should be apportioned
- Whether reported limitations are consistent with objective findings
Two physicians can therefore agree about what is medically wrong while reaching very different conclusions about what the condition means within a workers’ compensation claim.
What is the QME expected to explain?
A strong medical-legal opinion needs more than a conclusion.
California’s rules governing physicians’ reports as evidence identify a series of elements that should appear when applicable, including the injury history, complaints, medical history, examination findings, diagnosis, disability and work limitations, causation, future care, permanent disability, apportionment, and the reasons supporting the physician’s opinions.
The last part matters.
A report stating that the worker can return to unrestricted duty is much less useful if it never explains why the treating physician’s restrictions are no longer supported.
Likewise, a treating report stating that the worker remains unable to work carries less persuasive force if it does not explain what medical findings support that conclusion.
The dispute eventually becomes one of reasoning.
What makes one medical opinion more persuasive?
There is no single factor.
The strongest opinion generally fits several pieces together.
The physician had an adequate medical history
The report should reflect relevant prior injuries, medical conditions, treatment, and changes in symptoms.
An opinion based on an incomplete history may rest on an incorrect assumption from the beginning.
The important records were actually reviewed
Record volume alone says little about quality.
What matters is whether the physician identified and addressed the records that materially affect the disputed question.
A 4,000-page review can still miss the most relevant operative report. A 400-page file can still contain everything needed to reach a well-supported opinion.
The examination findings support the conclusion
If the physician relies heavily on the current physical examination, the reader should understand which findings mattered and why.
A major conclusion based on vague references to a “normal examination” invites questions.
Contrary evidence is addressed
This is particularly important when another physician has already reached a different opinion.
The QME does not need to agree with the treating physician. The report should show that the competing opinion was considered.
For example:
The treating physician believes continued restrictions are necessary because of persistent weakness.
The QME finds full strength on examination and believes the worker can return without restrictions.
A useful report explains the discrepancy. It might discuss changes over time, differences in testing, intervening treatment, or why the current findings are more representative of present function.
Simply stating a different conclusion leaves the core disagreement unresolved.
The physician explains the path from evidence to opinion
A reader should be able to follow:
Evidence → medical interpretation → conclusion
That becomes especially important in causation and apportionment, where the final percentage or opinion can look arbitrary without the reasoning underneath it.
What if the treating physician has more experience with the patient?
Longitudinal treatment is important, but familiarity does not automatically settle a disputed medical issue.
A treating physician may know the patient extremely well while having limited information about prior claims or nonindustrial conditions.
The QME may have a broader evidentiary record but less clinical history with the worker.
Each physician may therefore hold an advantage in a different part of the analysis.
The most useful comparison asks:
- What information did each physician have?
- What question was each physician answering?
- What findings did each physician rely on?
- Did either physician address the contrary evidence?
- Did the medical condition change between examinations?
- Are they actually disagreeing about the same point?
Sometimes reports that initially look contradictory are describing the worker at different stages of recovery.
A treating physician may have imposed restrictions in February. The QME examines the worker in June after another four months of treatment and releases them to full duty.
Those opinions may both have been reasonable when they were made.
QME disagreements over treatment have an important limitation
California separates medical treatment disputes from the QME process.
DWC explains that a QME may be used when a worker disagrees with the treating physician about the injury, work restrictions, or temporary disability status. It also states plainly that a QME may not comment on a request for medical treatment. Since July 1, 2013, treatment disputes for all dates of injury are resolved through independent medical review.
The restriction is broader than a utilization review denial.
California’s QME regulations provide that for any evaluation performed on or after July 1, 2013, and regardless of the date of injury, an AME or QME shall not provide an opinion on any disputed medical treatment issue, but shall provide an opinion about whether the injured worker will need future medical care to cure or relieve the effects of an industrial injury.
That boundary is important because a QME report can address the medical condition and the need for future care while still operating within a workers’ compensation system that assigns specific disputes to different review processes.
Can the QME speak with the treating physician?
California regulations expressly allow the evaluator and the employee’s treating physician to consult when necessary to produce a complete and accurate report. Any new or additional information received from the treating physician must be noted in the evaluator’s report.
That can be valuable when the written record leaves an important clinical question unresolved.
A treating physician may be able to clarify why restrictions remained in place, what occurred during a particular treatment period, or whether a change in symptoms was documented outside the reports already provided.
Consultation does not mean the physicians have to reach the same conclusion.
It can help ensure they are disagreeing over the medicine rather than over missing information.
What happens after the QME report?
The practical effect depends on the issue being disputed and the posture of the claim.
A QME opinion may influence:
- Temporary disability
- Return-to-work planning
- Permanent disability evaluation
- Apportionment
- Future medical exposure
- Settlement discussions
- Litigation strategy
- Additional discovery
- Whether a party seeks clarification or supplemental reporting
The report becomes part of the medical evidence used to resolve the workers’ compensation dispute. DWC describes QMEs as playing a critical role in that process.
A disagreement may also continue.
An attorney may challenge the assumptions underlying the QME’s opinion. Additional records may be submitted. The evaluator may be deposed. A supplemental report may be requested. Another physician’s opinion may become relevant.
Medical-legal disputes rarely become persuasive because one report simply says “I disagree.”
They become persuasive when the underlying reasoning survives closer examination.
When disagreement is actually useful
Different medical opinions are often treated as a problem in the claim.
Sometimes they improve the quality of the analysis.
A treating physician may identify something the evaluator overlooked. A QME may uncover prior history that changes the understanding of causation. Conflicting examination findings may reveal that the worker’s condition has changed over time.
The disagreement forces the parties to identify the actual medical question.
That can be more useful than several reports repeating the same conclusion without examining the difficult parts of the case.
The quality of the disagreement matters
A QME and treating physician do not need to agree.
They do need to make their reasoning understandable.
The strongest medical reports make clear:
- What information was available
- What the physician observed
- Which facts influenced the opinion
- How contrary evidence was considered
- Where uncertainty remains
- Why the final conclusion follows from the medical evidence
When those elements are present, the disagreement becomes something the parties can evaluate.
When they are absent, the claim is left with two medical conclusions and very little help deciding between them.
