Applies to individual, small group and large group insured markets and to self-funded plans subject to Idaho Code title 41, chapters 40 or 41, for plan years starting on or after Jan 1, 2019. Carriers may apply medical necessity review. Treatments must be prescribed/ordered by a licensed physician or psychologist. Whether ERISA self-funded private-employer plans are reached is not addressed.
