Cal. Health & Safety Code § 11839.6

(a) The department shall establish a program for the operation and regulation of office-based narcotic treatment programs. An office-based narcotic treatment program established pursuant to this section shall meet either of the following conditions:
1. (1) Hold a primary narcotic treatment program license.
2. (2) Be affiliated and associated with a primary licensed narcotic treatment program. An office-based narcotic treatment program meeting the requirement of this paragraph shall not be required to have a license separate from the primary licensed narcotic treatment program with which it is affiliated and associated.
(b) For purposes of this section, “office-based narcotic treatment program” means a program in which interested and knowledgeable physicians and surgeons provide addiction treatment services, and in which community pharmacies or medication units supply necessary medication both to these physicians and surgeons for distribution to patients and through direct administration and specified dispensing services.
(c) Notwithstanding any other law or regulation, including Section 10020 of Title 9 of the California Code of Regulations, an office-based narcotic treatment program in a remote site that is affiliated and associated with a licensed narcotic treatment program may be approved by the department, if all of the following conditions are met:
1. (1) A physician may provide office-based addiction services only if each office-based patient is registered as a patient in the licensed narcotic treatment program and both the licensed narcotic treatment program and the office-based narcotic treatment program ensure that all services required under Chapter 4 (commencing with Section 10000) of Division 4 of Title 9 of the California Code of Regulations for the management of narcotic addiction are provided to all patients treated in the remote site.
2. (2) A physician in an office-based narcotic treatment program may provide treatment for an appropriate number of patients under the appropriate United States Drug Enforcement Administration registration. The primary licensed narcotic treatment program shall be limited to its total licensed capacity as established by the department, including the patients of physicians in the office-based narcotic treatment program.
3. (3) The physicians in the office-based narcotic treatment program shall dispense or administer pharmacologic treatments for narcotic addiction or a substance use disorder that have been approved by the federal Food and Drug Administration for the purpose of narcotic replacement therapy or medication-assisted treatment of substance use disorders.
4. (4) Office-based narcotic treatment programs, in conjunction with primary licensed narcotic treatment programs, shall develop protocols to prevent the diversion of medication. The department may develop regulations to prevent the diversion of medication.
(d) For purposes of this section, “remote site” means a site that is geographically or physically isolated from any licensed narcotic treatment program. Therefore, the requirements in this subdivision regarding a remote site do not apply to an office-based narcotic treatment program that holds a primary narcotic treatment program license.
(e) In considering an office-based narcotic treatment program application, the department shall independently weigh the treatment needs and concerns of the county, city, or areas to be served by the program.
(f) Nothing in this section is intended to expand the scope of the practice of pharmacy.
