Billed for Workers’ Comp Outpatient Surgery: What the October Fee Update Does—and Does Not—Change

If you receive a bill for workers’ comp outpatient surgery, the October 2026 fee update does not by itself make the charge your responsibility. First identify whether a work-injury claim is pending, whether the provider knows about it, and whether a written rejection of liability has been delivered to you. Those facts matter more to direct collection than a revised facility reimbursement rate.

DWC’s October 7 announcement updates hospital outpatient and ambulatory surgical-center payment rules for services rendered on or after October 1, 2026. It does not create a new patient copayment or decide whether a particular surgery is authorized.

What the October Fee Schedule Update Does—and Does Not—Change

Understanding administrative medical fee updates requires distinguishing between institutional payment caps and patient billing rules:

• What the update does: The order updates maximum allowable reimbursement amounts paid by employers and claims administrators to outpatient surgical facilities and hospitals. It aligns state allowances with the Centers for Medicare & Medicaid Services (CMS) Hospital Outpatient Prospective Payment System (OPPS) and Ambulatory Surgical Center (ASC) payment files for the fourth quarter of 2026.
• What the update does not do: The fee update does not create patient copayments, deductibles, or co-insurance obligations. It does not authorize a proposed outpatient surgical procedure, nor does it decide whether an underlying medical condition arose out of and occurred in the course of employment (AOE/COE).

Direct Patient Billing Protections Under Labor Code Section 3751(b)

California law establishes restrictions on collecting money directly from injured workers while a workers' compensation claim is pending. Statutory protections govern direct collection efforts:

Under Labor Code Section 3751(b), if an employee has filed a DWC-1 claim form pursuant to Section 5401, a medical service provider with actual knowledge of the pending claim is prohibited from collecting money directly from the employee for services intended to cure or relieve the effects of the injury. Statutory liability: A medical provider who violates Section 3751(b) is subject to the statute’s stated liability to the employee for three times the amount unlawfully collected, plus reasonable attorney’s fees and costs.

Exceptions and Limitations on Billing Rules

The prohibition against direct collection contains explicit statutory conditions and narrow limits:

• Written rejection exception: A provider may attempt direct collection only if the provider has received written notice that liability for the injury was rejected by the employer, and the provider has delivered a copy of that written rejection notice to the employee.
• Contested liability is not an automatic waiver: An employer's denial of liability shifts the claim posture, but it does not make every subsequent bill illegal or ensure that all medical care remains free. A written rejection and delivery of its copy address the exception in section 3751(b); they do not, by themselves, establish that every charge is owed or covered by personal health insurance. The underlying debt and coverage require separate review.
• Unrelated medical matters: The statutory protection applies specifically to treatment for the alleged work injury. Unrelated medical care rendered by the same facility remains subject to standard personal health coverage or direct patient billing.

Practical Steps if a Surgery Center Bills You During a Pending Claim

If an outpatient surgery center or medical provider sends a bill or collection notice while a workers' compensation claim is pending, take the following steps:

1. Do not ignore collection notices or legal demands.
2. Organize critical records: Retain itemized bills, dates of service, copies of the completed DWC-1 claim form, proof of transmission or delivery to the employer, written acceptance or rejection notices from the claims administrator, and any Explanation of Review (EOR) or Explanation of Benefits (EOB).
3. Notify the billing department in writing: Send a written notice to the provider's billing office stating that the treatment relates to a pending workers' compensation claim filed under Labor Code Section 5401. Cite Labor Code Section 3751(b) and request a corrected statement or a written legal basis for direct collection.
4. Provide claims administrator details: Supply the provider with the claims adjuster's name, claim number, and billing address so charges can be submitted to the correct administrative entity.

A bill or demand does not, by itself, establish that money was unlawfully collected. Section 3751(b)’s stated remedy concerns the amount unlawfully collected. Keep both the demand and any payment record when asking counsel to evaluate a potential violation.

Read the October DWC fee announcement and Labor Code section 3751. The underlying claim, treatment authorization, facility bill-review dispute, and direct patient collection are separate questions. A provider’s fee dispute is not automatically a debt that the injured worker must pay.
