Cal. Ins. Code § 11754.1
If the commissioner has good cause to believe such noncompliance to be wilful, or if within the period prescribed by the commissioner in the notice required by Section 11754 the organization or insurer does not make such change as may be necessary to correct the noncompliance specified by the commissioner or establish to the satisfaction of the commissioner that such noncompliance does not exist, then the commissioner may hold a public hearing in connection therewith, provided that within a reasonable period of time, which shall not be less than 10 days before the date of such hearing, he shall mail written notice specifying the matters to be considered at such hearing to such organization or insurer. Such notice shall conform to the requirements for an accusation as prescribed by Section 11503 of the Government Code. If no notice has been given as provided in Section 11754 such notice shall state therein in what manner and to what extent noncompliance is alleged to exist. The hearing shall not include any additional subjects not specified in the notices required by Section 11754 or this section.
