(a) For the fiscal years prior to the 2004–05 fiscal year, and subject to the requirements of federal law, the maximum allowable rates for the Drug Medi-Cal Treatment Program shall be determined by computing the median rate from available cost data by modality from the fiscal year that is two years prior to the year for which the rate is being established.

(b) (1) For the 2007–08 fiscal year, and subsequent fiscal years, and subject to the requirements of federal law, the maximum allowable rates for the Drug Medi-Cal Treatment Program shall be determined by computing the median rate from the most recently completed cost reports, by specific service codes that are consistent with the federal Health Insurance Portability and Accountability Act of 1996 (42 U.S.C. Sec. 300gg).

(2) For the 2005–06 and 2006–07 fiscal years, if the State Department of Health Care Services determines that reasonably reliable and complete cost report data are available, the methodology specified in this subdivision shall be applied to either or both of those years. If reasonably reliable and complete cost report data are not available, the State Department of Health Care Services shall establish rates for either or both of those years based upon the usual, customary, and reasonable charge for the services to be provided, as the department may determine in its discretion. This subdivision does not modify subdivision (h) of Section 14124.24, which requires certain providers to submit performance reports.

(d) Notwithstanding subdivision (a), the maximum allowable rate for group outpatient drug free services shall be set on a per person basis. A group shall consist of a minimum of 2 and a maximum of 12 individuals, at least one of which shall be a Medi-Cal eligible beneficiary. For groups consisting of two individuals, if one of the individuals is ineligible for Medi-Cal, the individual who is ineligible for Medi-Cal shall be receiving outpatient drug free services for a substance use disorder diagnosed by a physician.

(e) The department shall develop individual and group rates for extensive counseling for outpatient drug free treatment, based on a 50-minute individual or a 90-minute group hour, not to exceed the total rate established for subdivision (d).

(f) (1) Notwithstanding Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code, the department may implement, interpret, or make specific this section by means of bulletins or similar instructions until the time any necessary regulations are adopted. The department shall adopt regulations by July 1, 2020, in accordance with the requirements of Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code. Beginning six months after the effective date of the act that added this paragraph, and notwithstanding Section 10231.5 of the Government Code, the department shall, on a semiannual basis and in compliance with Section 9795 of the Government Code, provide a status report to the Legislature until the regulations have been adopted.

(2) Notwithstanding paragraph (1) and Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code, the department may annually establish and update the statewide maximum allowable reimbursement rates specified in this section by means of bulletins or similar instructions.
