Belanger: Internal Forwarding Did Not Replace the Second-Review Service Date

A medical provider seeking additional reimbursement after receiving a partial payment must request a second bill review within 90 days of service of the Explanation of Review (EOB). Under California Labor Code section 4603.2(e)(2), if the only dispute concerns the payment amount and the provider fails to serve a second review request within that 90-day window, the bill is deemed satisfied by operation of law. In Robert Belanger v. City of Simi Valley, No. ADJ11788125 (Cal. WCAB Oct. 22, 2026), the Workers’ Compensation Appeals Board (WCAB) held that internal transaction logs showing when a hospital entered a check into its database and FedEx receipts showing inter-office shipping between hospital locations do not prove delayed receipt or rebut a properly established mailing date.

Bifurcated Trial and Conflicting Records of Mailing

The applicant sustained an industrial injury while working as a crossing guard, and the parties settled the primary claim by Compromise and Release in April 2021. Los Robles Regional Medical Center served an itemized UB-04 bill for emergency medical services totaling $1,518,464.53. The self-insured employer paid $214,482.49 by check dated February 5, 2019. The hospital mailed a request for second bill review on June 8, 2019, and filed a lien for the remaining $1,303,982.04 balance on August 5, 2019. At trial, the Workers’ Compensation Administrative Law Judge (WCJ) bifurcated the proceeding on his own motion to determine only two issues: The timeliness of the second bill review request and the application of the statutory mailbox rule.

To establish when the EOB and check were served, the employer submitted a written business records affidavit from its workers’ compensation supervisor detailing its weekly check-auditing cycle. The affidavit stated that the bill review administrator mailed the EOB and check on February 6, 2019, to the hospital’s address in Thousand Oaks, California. The hospital did not object to admitting the affidavit into evidence as proof of service. To contend that its June 8, 2019 second review request was timely within 90 days, the hospital argued it did not receive payment until March 13, 2019. In support, the hospital introduced an internal Artiva Workstation transaction report showing the check was logged into its software on March 13, 2019, alongside a FedEx overnight tracking slip bearing the same date. The WCJ issued a Findings and Order disallowing the hospital’s lien, finding the employer’s affidavit credible regarding a February 6, 2019 mailing date.

The WCAB Corrects Credibility Analysis but Affirms Disallowance

On reconsideration, the Appeals Board affirmed the take-nothing order while correcting the WCJ’s legal analysis. Citing Johanson v. San Ramon Valley Unified School District and Garza v. Workmen’s Comp. Appeals Bd., the Board explained that a trier of fact cannot base a demeanor credibility determination on a written affidavit without live testimony. However, the Board affirmed the disallowance because the hospital failed to sustain its affirmative burden of proof on the existing record.

Under Evidence Code section 641 and the mailbox rule articulated in Suon v. California Dairies, a letter correctly addressed and properly mailed is presumed received in the ordinary course of mail. While a recipient can rebut this presumption with believable contrary evidence, the hospital’s evidence failed to show delayed receipt. The FedEx tracking slip relied upon by the hospital showed shipping from its own address in Thousand Oaks to its corporate billing office in College Park, Georgia—documenting internal forwarding rather than external delivery from the employer. Furthermore, the internal software entry reflected when hospital personnel processed the check, not when it arrived in the mail. Because the hospital failed to prove a March 13 receipt date, its June 8 second review request was definitively untimely under Labor Code section 4603.2(e)(1). Belanger, opinion, pages 4–6.

Forfeiture of OMFS Exemption Arguments and Reach of the Ruling

The hospital also argued on reconsideration that its emergency room services were exempt from the Official Medical Fee Schedule (OMFS) and therefore excluded from second bill review and Independent Bill Review (IBR). The WCAB declined to reach this issue. Because the trial was bifurcated specifically to resolve timeliness and the mailbox rule, and the hospital did not object to bifurcation at trial, the hospital forfeited its exemption argument for reconsideration.

As a panel decision, Robert Belanger v. City of Simi Valley is persuasive authority rather than binding precedent under Gee v. Workers’ Comp. Appeals Bd.. The decision turns on the evidence actually admitted and the hospital’s failure to establish a timely request. For another dispute, identify the mailing proof, the meaning of internal entries and the precise issue set for trial. This October 22 decision is discussed as an existing billing-dispute decision, not a newly issued October 30 ruling.

The mailing evidence identified MCMC LLC as the bill-review provider that mailed the documents. Its supervisor’s business-records affidavit was admitted without objection. The hospital’s later internal routing evidence therefore had to be assessed against the admitted mailing evidence, rather than treated as a substitute service date. Belanger, decision, page 2–5.

The panel’s service analysis draws on Suon, 83 Cal.Comp.Cases 1803, 1817 (2018), an en banc WCAB decision. It also observed that a formal proof of service would have established mailing more clearly than the business-records affidavit. The underlying findings issued in June 2022; October 22, 2026 is the reconsideration decision analyzed here.
