Cal. LAB § 139.43

(a) No person or entity shall advertise, print, display, publish, distribute, or broadcast, or cause or permit to be advertised, printed, displayed, published, distributed, or broadcast in any manner, any statement concerning services or benefits to be provided to an injured worker, that is paid for directly or indirectly by that person or entity and is false, misleading, or deceptive, or that omits material information necessary to make the statement therein not false, misleading, or deceptive.

(b) As soon as reasonably possible, but not later than January 1, 1994, the administrative director shall adopt regulations governing advertising by persons or entities other than physicians and attorneys with respect to services or benefits for injured workers. In promulgating regulations pursuant to this subdivision, the administrative director shall review existing regulations, including those adopted by the State Bar, to identify those regulatory approaches that may serve as a model for regulations required by this subdivision.

(c) A violation of subdivision (a) is a misdemeanor, punishable by incarceration in the county jail for not more than one year, or by a fine not exceeding ten thousand dollars ($10,000), or both.

(d) This section shall not apply to physicians or attorneys. It is the intent of the Legislature to exempt physicians and attorneys from this section because the conduct regulated by this section, with respect to physicians and attorneys, is governed by other provisions of law.
