The main purpose of this legislation is to extend incentive payments for healthcare providers who participate in alternative payment models under the Medicare program. These models are designed to improve care quality and reduce costs by encouraging providers to focus on patient outcomes rather than the volume of services provided. Key provisions of the legislation include extending the timeline for these incentive payments from 2026 to 2027, and adjusting the percentage of the incentive payment for the year 2027 to 3.53 percent.
