To amend title XVIII of the Social Security Act to increase data transparency for supplemental benefits under Medicare Advantage.

This bill would require Medicare Advantage plans to share detailed data about the “extra” benefits they offer—things beyond regular medical care—so people can see what’s actually available and used. Starting in 2029, plans must report enrollee-level information on these supplemental benefits, including who is eligible, what benefit categories are offered, how often they’re used, what the plan spends per person who uses them, and what patients pay out of pocket each time. The data must include the type of item or service and the provider’s national identifier.

Beginning in 2030, the government must release this data each year for program studies and other health research, and also post a public-use file online, while protecting people’s privacy. The bill does not change any data collections already proposed in a March 14, 2023 notice.

• Who is affected: People enrolled in Medicare Advantage, the insurance plans that serve them, researchers, and the public.
• What changes: Plans must report detailed, person-level data on supplemental benefits; the government makes the data available yearly with privacy safeguards.
• When: Plan reporting starts with the 2029 plan year; yearly public release begins in October 2030.
