Create a new section of KRS 304.17A-660 to 304.17A-669 to define "psychiatric collaborative care model"; require the commissioner of insurance to promulgate and maintain an administrative regulation to list alterations and additions to relevant billing codes; require health benefit plans that provide coverage for treatment of a mental health condition to provide reimbursement for those benefits that are delivered through the psychiatric collaborative care model; authorize insurers to deny any benefit billed under a covered billing code on grounds of medical necessity if certain conditions are met; apply requirement to health benefit plans issued, delivered, or renewed on or after January 1, 2027; require the Department of Insurance to seek a federal waiver if cost defrayal is determined.
