- ADJ19265320 · 2026-01-30 · San Jose District Office§ 4603
Determinative passage · p.6A defendant has 60 days to review and analyze a medical-legal bill or invoice. (Lab. Code, § 4622(a)(1).) A defendant has two options within this 60-day window: It may pay the bill or invoice in full or pay less than the full amount. Should a defendant decide to pay less than the full amount within the 60-day window, it may still avoid the imposition of a penalty and interest by including an EOR with its payment. Section 4622 requires that a defendant object to the invoice or billing with an EOR as described in section 4603.3. (Lab. Code, § 4622(a)(1), (e)(1); 4603.3.) Objecting to an invoice with an EOR within the 60-day window is defendant's burden. If a defendant does not pay a proper medical-legal invoice in full or fails to provide an EOR within the 60-day window, then a defendant has waived all objections, other than compliance with sections 4620 and 4621, to the medical-legal provider's billing. (Cal. Code Regs., tit. 8, § 10786(e).) A defendant is then liable for the reasonable value of the medical-legal services as well as a 10 percent penalty and 7 percent per annum interest.
The WCJ's denial of penalties was based on the finding that the payment was not unreasonably delayed and that the EOR was not properly served, but the WCAB found the record insufficient to support this and granted reconsideration.
