Valdez: Non-MPN Treatment Reports Were Not Categorically Excluded

Valdez v. Workers' Compensation Appeals Board, 57 Cal. 4th 1231 (2013), rejected the view that an established medical provider network makes every outside physician's report inadmissible in a disability-benefit proceeding. The statutory exclusion concerned controversies arising under the MPN article. The Court affirmed the Court of Appeal's judgment, while emphasizing the amended statute's limit on using a privately retained doctor's report as the sole basis of an award.

The disposition was direct: “We affirm the Court of Appeal’s judgment” Slip opinion at 11.

A treatment choice became an evidentiary dispute

After a work-related fall, Valdez began treatment with an MPN physician. Dissatisfied, she obtained treatment from a non-MPN doctor recommended by her attorney without using the network's physician-change and second- or third-opinion process. She later relied on that doctor's reports when seeking temporary disability. The employer objected under Labor Code section 4616.6. Slip opinion at 4–6.

The workers' compensation judge admitted the reports and awarded benefits. The WCAB, acting en banc and assuming a validly established and properly noticed network, applied a broad exclusion and rescinded the award. The Court of Appeal annulled the Board's decisions. The Supreme Court granted review of the section 4616.6 issue.

What the decision means for workers

The opinion described the medical-legal evaluation provisions used to resolve compensation disputes and the separate MPN procedure for disagreements about diagnosis and treatment. Section 4616.6 barred other reports to resolve controversies arising out of the MPN article. The Board and employer sought to extend that restriction to disability-benefit determinations generally. Slip opinion at 1–3, 8–9.

The Court found that extension inconsistent with the limiting text. Article 2.3 did not address disability benefits, and there had been no proceeding under that article in Valdez's case. Other provisions authorized consideration of attending or examining physicians' reports and relevant medical records. The network framework did not supply an overarching rule excluding all medical evidence generated outside it.

The 2012 amendment confirmed a limited evidentiary role

While review was pending, Senate Bill 863 amended section 4605. The new language preserved an employee's ability to obtain consulting or attending physicians at personal expense, prohibited those reports from serving as the sole basis of an award, and required a QME or authorized treating physician to address their findings and explain agreement or disagreement. Slip opinion at 7–9.

The Court reasoned that a prohibition on using a report as the sole basis necessarily contemplated some permissible use. The Legislature had not amended section 4616.6 into the categorical exclusion the employer proposed. Current section 4605 retains that distinction. Admissibility is not the same as sufficiency, and neither guarantees that the factfinder will credit the report.

MPN structure survived the ruling

The employer argued that allowing outside reports would undermine network exclusivity. The Court responded that the statutes did not make MPNs the exclusive source of every medical consultation. It also recognized the reforms strengthening network procedures and restricting employer liability for unauthorized treatment. Those provisions could encourage network use without converting section 4616.6 into a universal evidentiary bar. Slip opinion at 10–11.

The employer additionally argued that Valdez had requested reimbursement and therefore was not retaining the doctor at her own expense. The Court said no reimbursement ruling was before it. It did not decide that bill. Nor did it hold that every privately hired medical-legal rebuttal expert is an attending or consulting physician within section 4605.

The remand remained subject to the amended statute

The Court affirmed the appellate judgment and stated that Senate Bill 863's amendments applied on remand because Valdez's award was not final. It resolved the issue on statutory grounds and did not reach her constitutional arguments. The decision therefore should not be described as an unconditional affirmance of the original benefit award or a constitutional right to bypass medical-legal procedures.

Was the private report enough on its own?

The amended section 4605 prohibited using such a report as the sole basis of an award.

Were reimbursement and constitutional claims decided?

No. Reimbursement was outside the issue presented, and the statutory ruling made constitutional review unnecessary.
