California Code, Welfare and Institutions Code - WIC § 14043.55

(a) The department may implement a 180-day moratorium on the enrollment of providers in a specific provider of service category, on a statewide basis or within a geographic area, except that no moratorium shall be implemented on the enrollment of providers who are licensed as clinics under Section 1204 of the Health and Safety Code, health facilities under Chapter 2 (commencing with Section 1250) of the Health and Safety Code, clinics exempt from licensure under Section 1206 of the Health and Safety Code, or natural persons licensed or certified under Division 2 (commencing with Section 500) of the Business and Professions Code, the Osteopathic Initiative Act,  1 or the Chiropractic Initiative Act,  2 when the director determines this action is necessary to safeguard public funds or to maintain the fiscal integrity of the program. This moratorium may be extended or repeated when the director determines this action is necessary to safeguard public funds or to maintain the fiscal integrity of the program. The authority granted in this section shall not be interpreted as a limitation on the authority granted to the department in Section 14105.3.

(b) If the Secretary of the United States Department of Health and Human Services establishes a temporary moratorium on enrollment as described in federal regulations, the department shall establish a corresponding moratorium covering the same period and provider types, even if those provider types would not ordinarily be subject to a moratorium under this section, unless the department determines that the imposition of the moratorium will adversely impact beneficiaries access to medical assistance. A federal moratorium adopted under this subdivision shall not be subject to the director's determinations regarding safeguards of public funds and program integrity or other prerequisites that are necessary to implement a state-initiated moratorium.
