This bill seeks to enhance Medicare coverage for mental and behavioral health services when provided via telehealth. It accomplishes this by making specific amendments to Section 1834(m)(7) of the Social Security Act, which outlines Medicare's telehealth provisions. The legislation broadens the scope of covered services by replacing "mental health services" with "mental and behavioral health services" furnished through telehealth. It also eliminates a restrictive subparagraph and clarifies coverage for behavioral health disorders. These amendments are designed to take effect retroactively, aligning with the enactment date of section 123 of division CC of the Consolidated Appropriations Act, 2021.
