IMR Denies Six Months of Home Care: Is the Reason a Factual Error?

A California workers’ compensation IMR determination can acknowledge that some home care is reasonable while rejecting the particular hours or duration requested. That wording alone does not establish an appealable factual error. The important comparison is between the exact request, the records submitted and the reason given—not simply between a favorable phrase and an unfavorable result.

The January 9, 2026 WCAB order in Bell v. Disneyland, No. ADJ15245137, illustrates the question without resolving it. The panel granted reconsideration for further review and expressly deferred a final merits decision. It did not find a qualifying factual mistake, overturn IMR or award home care. This discussion describes that January 9 order, not a later disposition or a claim that the matter remains pending today.

Identify the complete treatment request

Separate the tasks, hours per day, days per week, total duration and any planned reassessment. Approval of an assessment is different from approval of the care the assessment recommends. Similarly, a conclusion that some assistance is reasonable does not establish four hours daily for six months without another evaluation.

In Bell, the record included a physician’s request for home health aide assistance four hours per day, seven days per week, for six months. UR separately approved one home-care assessment. The IMR rationale acknowledged a need for assistance with daily activities and household tasks but described six months without reassessment as excessive. See pages 4–5. Those distinctions should be preserved before describing the denial as contradictory.

Compare four parts of the file

A useful comparison identifies what each decision-maker actually received and decided. Keep complete documents alongside the summary rather than copying only the favorable sentence.

• Physician’s RFA: Identify the requested tasks, frequency, duration and supporting assessment. Note any amended request and proof of transmission.
• UR decision: Match its approved, modified or denied service to that RFA. List the reports it identifies as reviewed and any uncertainty about attachments.
• IMR submission and record list: Identify documents supplied by the worker and administrator, with delivery evidence. Do not assume the UR and IMR records were identical.
• IMR rationale: Locate the precise statement challenged and determine whether it concerns a record fact, requested scope, clinical need or reassessment interval.

The panel’s preliminary review in Bell could not determine whether UR considered the nurse’s assessment incorporated into the physician’s report. But the order expressly states that IMR reviewed that assessment, along with other records. See page 5. It would therefore be inaccurate to summarize the order as finding that IMR never received the assessment. Receipt, consideration and the medical conclusion are separate questions.

Distinguish an ordinary factual mistake from clinical judgment

Labor Code section 4610.6(h) presumes the Administrative Director’s determination correct and requires clear and convincing evidence of a listed ground to set it aside. Those grounds concern excess of authority, fraud, a qualifying material conflict of interest, bias on a statutorily listed protected basis, or a plainly erroneous factual finding involving ordinary knowledge rather than expert opinion. A disagreement with the medical recommendation is not a substitute ground.

For example, whether an identified report was submitted can be tested against the report and transmission record. Whether a patient needs a particular level of assistance for six months without reassessment may require clinical judgment. Even a demonstrably inaccurate record statement must be connected to the statutory ground and the determination; finding an error somewhere in the paperwork does not automatically establish entitlement to reversal.

In Bell, the panel said its preliminary review left uncertainty about the sufficiency of the record and whether the determination rested on a qualifying factual error. See pages 6–7. It preserved those questions for further consideration. The grant was not a holding that the duration rationale was legally defective.

Preserve the appeal deadline and the limited remedy

Section 4610.6(h) requires a verified appeal filed with the WCAB and served on interested parties within 30 days of mailing to the aggrieved employee or employer. WCAB Rule 10575 states a filing deadline of no later than 30 days after service and requires the determination and its proof of service. Preserve the mailing and service evidence and have the applicable deadline calculated promptly; do not assume it runs from when you read the decision.

The rule requires specific factual and legal grounds and identifies service on the IMR Unit, the ADJ and IMR case numbers, and the required petition caption. An informal complaint, request for records or discussion of a revised RFA should not be assumed to replace the appeal or extend its deadline.

If an IMR determination is reversed, section 4610.6(i) requires remand for review by a different IMR organization, or a different reviewer in the original organization if another organization is unavailable. It does not authorize the judge to substitute a contrary medical-necessity determination. That remedy differs from obtaining an immediate award of the requested six months.

If the actual problem is that approved care was never delivered, our undelivered home-care guide addresses that separate record. For review of a denial, bring the RFA, UR decision, IMR packet, rationale and service evidence to our workers’ compensation practice.
