To amend title XVIII of the Social Security Act to require MA organizations offering network-based plans to maintain an accurate provider directory, and for other purposes.

This bill requires Medicare Advantage (MA) plans to maintain accurate, publicly accessible provider directories containing essential details like provider names, specialties, contact information, and accessibility features. MA organizations must verify directory accuracy quarterly (or annually for hospitals), remove outdated providers within 5 business days, and clearly flag outdated information. If a beneficiary relies on an incorrect directory listing for a non-participating provider, the MA plan must cover the same cost-sharing as if the provider were in-network. These requirements apply to all network-based MA plans starting in 2026, with annual accuracy reports and public score disclosures beginning in 2027.
