The purpose of this legislation is to create a new review process for decisions made about drug coverage under the Medicare program. Specifically, it aims to ensure that patients have better access to innovative treatments by allowing for a reassessment of national coverage determinations that may deny or limit coverage for certain drugs. Key provisions of the legislation include a structured review process for national coverage determinations. When a request for review is made, the Secretary of Health and Human Services must start the review within 90 days.
