CA SB70

Prohibits health care service plans and health insurers from denying or limiting coverage of a drug, dose, or dosage form prescribed for off-label use if the drug was previously covered for a chronic condition or cancer, regardless of formulary status.

Requires health insurance policies issued after January 1, 2024, to maintain coverage for previously approved drugs, doses, or dosage forms without additional cost sharing beyond what was already imposed, allowing only tier-based adjustments for dosage changes.

Expands existing off-label drug coverage protections to include chronic and seriously debilitating conditions (in addition to life-threatening conditions) when recognized by specified medical compendia or peer-reviewed journals.

Applies the new protections to both health care service plan contracts and individual or group health insurance policies, with exemptions for Medicare supplement, vision-only, and dental-only policies.

Exempts local agencies and school districts from reimbursement requirements under the California Constitution because any costs result from changes to criminal provisions in the Health and Safety Code.
