Prescription drug coverage: dose adjustments.

Changed 'treating provider' to 'treating contracting provider,' limiting who may request dose adjustments to providers with an active contract with the plan or insurer.

Narrowed the covered condition from 'chronic medical condition' to 'serious chronic condition, as defined in Section 1373.96' (Health and Safety Code) or 'Section 10133.56' (Insurance Code), reducing the range of conditions for which dose adjustments are protected.

Added a requirement that the health care service plan or health insurer must issue a written response to the requesting provider within 72 hours of receipt of the request.

Added a new subdivision (b) to both sections stating that the provision does not apply to a drug or adjusted dose used for a purpose different from what the FDA has approved for marketing, unless it additionally meets the conditions in Section 1367.21 or Section 10123.195. This significantly restricts off-label use protections.

Changed the process language from providers being granted authority to submit a written request and receive a written response, formalizing the interaction between provider and plan/insurer.

The bill text was reformatted from a formal enrolled document layout (with passage dates, Governor's receipt line, and page numbering) to a web page presentation that includes site navigation elements, a version history list, status timeline, and share links. No changes were made to the substantive provisions of Sections 1367.225 (Health and Safety Code), 10123.1934 (Insurance Code), or Section 3 (no reimbursement).

The person authorized to request dose or frequency adjustments was narrowed from 'a licensed health care professional' to specifically 'an enrollee's or insured's treating provider,' limiting who can invoke this right.

A new condition requires that if the adjusted dose or frequency is for an off-label use, two articles from major peer-reviewed medical journals must have presented data supporting the proposed off-label use as generally safe and effective. This applies to both the Health and Safety Code (Section 1367.225) and Insurance Code (Section 10123.1934) provisions.

A provision that would have prohibited health care service plans and insurers from limiting or excluding coverage of a prescription drug that an enrollee or insured had been continuously using while covered by current or previous health coverage was entirely removed from both sections.

Changed the person authorized to request dose adjustments from 'a licensed health care professional' to 'an enrollee's treating provider' (Health and Safety Code section 1367.225) and 'an insured's treating provider' (Insurance Code section 10123.1934). This narrows eligibility from any licensed clinician to specifically the provider who has been treating the patient.

Changed the condition for continued coverage from requiring that 'the plan's prescribing provider continues to prescribe' to 'the enrollee's treating provider continues to prescribe' (and similarly for insurers). This ensures continuity is tied to the same treating provider rather than any provider associated with the plan.
