What panels did with this rule
Released decisions that named § 9785, with the passage each turned on. A panel decision persuades; it does not bind.
- ADJ21245209 · 2026-08-14 · Fresno District Office8 CCR § 9785
Determinative passage · p.4The WCJ found that the QME process was not correctly initiated apparently because the QME process is triggered by an objection to a “primary treating physician” and that neither Nurse Uichanco, nor Dr. Roach was a “primary treating physician.” However, Labor Code section 3209.10(a) plainly states:
Defines the primary treating physician and its interpretation in harmony with Labor Code section 3209.10.

Determinative passage · p.7selected by the employer, the employee pursuant to Article 2 (commencing with section 4600) of Chapter 2 of Part 2 of Division 4 of the Labor Code, or under the contract or procedures applicable to a Health Care Organization certified under section 4600.5 of the Labor Code, or in accordance with the physician selection procedures contained in the medical provider network pursuant to Labor Code section 4616.
The designation of Concentra as the primary treating physician was invalid as it is an entity, not a physician.

Determinative passage · p.5IV. We highlight the following legal principles that may be relevant to our review of this matter: Section 4060(b) allows a medical-legal evaluation by the treating physician. Section 4620(a) defines medical-legal expense as “any costs and expenses … for the purpose of proving or disproving a contested claim.” Section 4064(a) provides that the employer is liable for the cost of a comprehensive medical evaluation that is authorized by section 4060. The regulations provide that the “primary treating physician shall render opinions on all medical issues necessary to determine the employee's eligibility for compensation …” (Cal. Code Regs., tit. 8, § 9785(d).)
These provisions govern the entitlement and timing of medical-legal reports and reimbursement of related expenses.

Determinative passage · p.5In the present case, applicant designated Casa Colina rather than any individual physician as her primary treating physician. This designation violates AD Rule 9785(a)(1), which defines the primary treating physician as an actual physician and not a facility or other entity.
Applicant's designation of Casa Colina, a facility, as primary treating physician violates this regulation.

Determinative passage · p.2Where defendant has accepted liability for an injury, the compensability of an additional body part is ordinarily a medical determination to be made by the primary treating physician pursuant to section 4062. (See Lab. Code, § 4060(a), 4062.) In cases where applicant is being provided treatment, the ordinary procedure is to first obtain the opinion of the primary treating physician who "shall render opinions on all medical issues necessary to determine the employee's eligibility for compensation[.]" (Cal. Code Regs., tit. 8, § 9785(d).) In cases where the additional body part is outside the expertise of the primary physician, the primary physician should refer applicant to a secondary physician who "shall report to the primary physician in the manner required by the primary physician." (Id. at § 9785(e)(3).) Then, the primary physician "shall be responsible for obtaining all of the reports of the secondary physicians and...
Described the ordinary procedure for obtaining an additional panel in accepted claims and the alternative procedure in denied claims.

Determinative passage · p.8We again observe, however, that following defendant's denial of all liability for applicant's claim on August 9, 2023, any medical treatment sought by applicant in response to her alleged industrial injuries would necessarily be self-procured. (Lab. Code, § 4600(a); McCoy v. Industrial Acc. Com. (1966) 64 Cal.2d 82 [31 Cal.Comp.Cases 93].) And while treatment to cure or relieve from the effects of an industrial injury is statutorily authorized under section 4600(a), a treating physician may, in the exercise of their medical judgment, declare an injured worker to be permanent and stationary. The determination is based on an assessment of whether the injured worker's "condition is well stabilized, and unlikely to change substantially in the next year with or without medical treatment." (Cal. Code Regs., tit. 8, § 9785(a)(8); § 10116.9(m); italics added.) Thus, a treating physician is authorized to determine that an injured worker has reached a permanent and stationary plateau and issue the corresponding reporting irrespective of whether medical treatment is anticipated to change applicant's condition over the following year.
The WCAB applied these standards to find the treating physicians' reports admissible despite defendant's objections, as defendant relinquished medical control after denying liability.

Determinative passage · p.2We will briefly review the relevant facts.

On January 1, 2024, applicant filed an Application for Adjudication (Application). On March 13, 2024, applicant's attorney designated Arbi Mirzaians, D.C., as applicant's primary treating physician (PTP) pursuant to Labor Code section 4600(c) and AD Rule 9785(b)(2) (Cal. Code Regs., tit. 8, § 9785(b)(2).) The letter requested that he prepare a medical-legal evaluation report.
Applied to the designation of Dr. Arbi Mirzaians as PTP and request for medical-legal evaluation.

Determinative passage · p.4comply with CCR Section 9785 (a) (8), "permanent and stationary status is the point where the employee has reached maximal medical improvement, meaning his or her condition is well stabilized and unlikely to change substantially in the next year with or without medical treatment."
Defines permanent and stationary status as maximal medical improvement, relevant to termination of temporary disability benefits.
