Statute Text

(b)(2) A properly documented list of services provided and not paid at the rates then in effect under Section 5307.1 within the 45-day period shall be paid at the rates then in effect and increased by 15 percent, together with interest at the same rate as judgments in civil actions retroactive to the date of receipt of the itemization, unless the employer does both of the following:

(A) Pays the provider at the rates in effect within the 45-day period.

(B) Advises, in an explanation of review pursuant to Section 4603.3, the physician, or another provider of the items being contested, the reasons for contesting these items, and the remedies available to the physician or the other provider if he or she disagrees. In the case of an itemization that includes services provided by a hospital, outpatient surgery center, or independent diagnostic facility, advice that a request has been made for an audit of the itemization shall satisfy the requirements of this paragraph.
An employer’s liability to a physician or another provider under this section for delayed payments shall not affect its liability to an employee under Section 5814 or any other provision of this division.
