Substance use disorder coverage.

Existing law requires health care service plan contracts and health insurance policies that provide hospital, medical, or surgical coverage and are issued, amended, or renewed on or after January 1, 2021, to provide coverage for medically necessary treatment of mental health and substance use disorders under the same terms and conditions applied to other medical conditions, as specified.

On and after January 1, 2027, this bill would prohibit concurrent or retrospective review of medical necessity of in-network health care services and benefits (1) for the first 28 days of a treatment plan for inpatient or residential substance use disorder stay at a specified licensed facility during each plan or policy year or (2) for outpatient services provided by specified certified programs for substance use disorder visits, except as specified. The bill would authorize, after the 29th day, in-network health care services and benefits for inpatient or residential substance use disorder care to be subject to concurrent review. On and after January 1, 2027, the bill would prohibit retrospective review of medical necessity for the first 28 days of intensive outpatient or partial hospitalization services for substance use disorder, but would authorize concurrent or retrospective review for day 29 and days thereafter of that stay or service. With respect to health care service plans, the bill would specify that its provisions do not apply to Medi-Cal behavioral health delivery systems or Medi-Cal managed care plan contracts. Because a willful violation of the bill's requirements by a health care service plan would be a crime, the bill would impose a state-mandated local program.

The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that no reimbursement is required by this act for a specified reason.
