To amend title XVIII of the Social Security Act to extend incentive payments for participation in eligible alternative payment models.

HR 6369 extends Medicare incentive payments for healthcare providers participating in "eligible alternative payment models" (APMs), which are alternative Medicare payment structures for doctors and clinics. The bill updates payment rules to cover 2026 instead of 2025, adding a new rule that reduces 2026 payments by 34% for providers in their 4th-6th year of APM participation and by 67% for those in their 7th year or longer. These changes directly affect Medicare-certified healthcare professionals and organizations enrolled in APMs, altering their payment incentives based on years of participation. The bill amends Section 1833(z) of the Social Security Act to adjust payment timelines and reduction percentages, with related updates to other Medicare payment provisions.
