Medicare Program: Mitigating the Impact of Significant, Anomalous, and Highly Suspect Billing Activity on Medicare Shared Savings Program Financial Calculations in Calendar Year 2023

This proposed rule addresses policies for assessing performance year (PY) 2023 financial performance of Medicare Shared Savings Program (Shared Savings Program) Accountable Care Organizations (ACOs); establishing benchmarks for ACOs starting agreement periods in 2024, 2025, and 2026; and calculating factors used in the application cycle for ACOs applying to enter a new agreement period beginning on January 1, 2025, and the change request cycle for ACOs continuing their participation in the program for PY 2025, as a result of significant, anomalous, and highly suspect billing activity for selected intermittent urinary catheters on Medicare Durable Medical Equipment, Prosthetics, Orthotics & Supplies (DMEPOS) claims. Under the Shared Savings Program, providers of services and suppliers that participate in ACOs continue to receive traditional Medicare fee-for-service (FFS) payments under Medicare Parts A and B, but the ACO may be eligible to receive a shared savings payment if it meets specified quality and savings requirements. ACOs participating in two-sided models may also share in losses.
