What was disputed, and how it came out
Each issue the panel decided, with the reasoning it gave. An outcome is what this panel did on this record — not a rule, and not a prediction.
Applicant failed to identify any medical report or record reviewed by IMR that would support the argument that the IMR determination was based on a plainly erroneous finding of fact. The June 2, 2025 report by PTP Dr. Hannani was not reviewed by IMR and did not specify any new diagnostic evidence. The difference of opinion between IMR and PTP reports requires expert opinion and is not a matter of ordinary knowledge.
From the decision · page 94. Petitioner contends that the court erred by finding that: a. The Independent Medical Review (IMR) determination dated July 22, 2025 was NOT based on a plainly erroneous express or implied finding of fact requiring reversal. b. The June 2, 2025 report from PTP Dr. Kambiz Hannani failed to identify a material change in circumstances requiring a new utilization review following the May 20, 2025 utilization review denial. FACTS
The June 2, 2025 report by PTP Dr. Hannani did not identify any material change in the applicant's medical condition subsequent to the May 20, 2025 utilization review denial. The reports were nearly identical except for clarifying paragraphs that did not constitute new evidence. Applicant's testimony of worsening symptoms did not specify a material change after the May 20, 2025 denial. Therefore, no new utilization review was required and the June 5, 2025 deferral was reasonable.
From the decision · page 11Next, applicant argues that the June 2, 2025 report by PTP Dr. Hannani "contained new and significant medical findings" requiring that defendant conduct a new UR despite the May 20, 2025 UR denial of the same surgery recommended in Dr. Hannani's May 9, 2025 report. However, based on a line-by-line comparison of Dr. Hannani's May 9, 2025 and June 2, 2025 reports, it is noted that the reports are identical except for 4 paragraphs at the bottom of page 3 of the June 2, 2025 report. In other words, the sections of the reports under the headings of Subjective Complaints, Objective Complaints, Motor Examination, Sensation, Reflexes, Lower Extremities Examination, Bilateral Hips, Vascular Examination, Diagnosis, Prescriptions Given and Disability Status are word for word the same.
The facts that decided it
What the panel treated as outcome-determinative, and which side it favoured.
Applicant failed to identify any medical report reviewed by IMR that contradicted the IMR finding of no evidence of concomitant instability to support surgery request
Favours Defendant prevailed
Without such evidence, the IMR determination was not based on a plainly erroneous finding of fact and was upheld
From the decision · page 11IMR did not state that there was "no instability." IMR stated that, "the medical records did not include evidence of concomitant instability to support the request." Again however, applicant failed to identify and/or offer into evidence any report reviewed by IMR to contradict this finding.
June 2, 2025 report by PTP Dr. Hannani did not specify any new diagnostic evidence or material change from May 9, 2025 report
Favours Defendant prevailed
This showed no material change in condition requiring a new utilization review, supporting the reasonableness of the June 5, 2025 UR deferral
From the decision · page 8Dr. Hannani does not, however, indicate in his June 2, 2025 report what x-rays he is referring to, when they were obtained or how they differ from any x-rays he might have relied upon in his May 9, 2025 report. In other words, Dr. Hannani's June 2, 2025 report fails to identify any change in the applicant's condition subsequent to the May 9, 2025 report and/or the May 20, 2025 utilization review.
What the panel did with the medical opinions
The role the physician served, and the weight the opinion carried. Physicians are named here as the decision names them; we do not score them.
Recommended back surgery with fusion and decompression at L4/L5 based on x-ray and MRI findings of instability and stenosis; June 2, 2025 report did not specify new diagnostic evidence or material change from May 9, 2025 report.
From the decision · page 7As for applicant's argument that there was a material change in circumstances supporting a new Request for Authorization such that defendant's June 5, 2025 Utilization Review deferral constituted a failure to conduct a timely Utilization Review, it is noted that both the May 9, 2025 and June 2, 2025 reports from PTP Dr. Hannani include the exact same paragraph (including typographical errors) describing the request for back surgery as follows:
The rules the panel named
Authorities as the decision cited them, with how this panel applied each one.
Labor Code section 4610(k)
Utilization Review decision remains effective for 12 months unless supported by documented material change in facts
A new utilization review is not required unless there is a documented material change in facts material to the original UR decision.
From the decision · page 10"(k) A utilization review decision to modify or deny a treatment recommendation shall remain effective for 12 months from the date of the decision without further action by the employer with regard to a further recommendation by the same physician, or another physician within the requesting physician's practice group, for the same treatment unless the further recommendation is supported by a documented change in the facts material to the basis of the utilization review decision."
Labor Code section 4610.6(h)
Labor Code section 4610.6(h) review standards for Independent Medical Review determinations
The Appeals Board may set aside an IMR determination only for specified reasons including plainly erroneous findings of fact not subject to expert opinion.
From the decision · page 3Under that authority, the AD's determination is presumed to be correct and may only be set aside by clear and convincing evidence of one or more of the following: (1) the AD acted without or in excess of his or her powers; (2) the AD's determination was procured by fraud; (3) the independent medical reviewer had a material conflict of interest; (4) the determination was the result of bias based on race, national origin, ethnic group identification, religion, age, sex, sexual orientation, color, or disability; or (5) the determination was the result of an erroneous finding of fact not subject to expert opinion. (Lab. Code, § 4610.6(h).) In Stevens v. Workers' Comp. Appeals Bd.
What proof carried it
The evidence the panel weighed, by kind.
Applicant's credible trial testimony that her back symptoms worsened during 2025 but did not specify a material change after the May 20, 2025 UR denial
From the decision · page 12At trial, applicant credibly testified that her back symptoms worsened during 2025 to the point that she is now willing to go forward with back surgery. However, the applicant was not asked and her testimony therefore did not identify any material change in her medical condition following the May 20, 2025 UR denial that would have required that defendant perform a second UR for the same surgery.
