Centers for Medicare & Medicaid Services (CMS) - Medicare Fee-for-Service (FFS)
High-priority program
Program level Payment Integrity results
Sponsoring agency: Department of Health and Human Services
Medicare Fee-for-Service (FFS) is a federal health insurance program that provides hospital insurance (Part A) and supplementary medical insurance (Part B) to eligible citizens. The primary causes of overpayments continue to be insufficient documentation and medical necessity errors for skilled nursing facilities, hospital outpatient, hospice, and home health claims. A known barrier to preventing improper payments is that providers' and suppliers' compliance with requirements is outside of the agency's control.

Prevention
In FY 2025, HHS launched the five-year Ambulatory Surgical Center Prior Authorization demonstration in 10 states to verify compliance with coverage, coding, and payment rules before services are rendered and claims are paid to prevent improper payments.
HHS continues to prioritize and implement effective corrective actions and mitigation strategies that reduce improper payments and unknown payments agency-wide as evidenced by its error rate of 6.55%, a decrease from 7.66% in FY 2024. The actions taken and planned to address the root causes of the improper payment rate and are proportional to the associated amount and address the root causes of the improper payments. For example, in FY 2025, the primary drivers of the improper payment rate are Skilled Nursing Facility (SNF), Hospital Outpatient, Inpatient Rehabilitation Facility (IRF), and Hospice claims. To drive down the improper payment rate, HHS continues nationwide prior authorization for hospital outpatient claims. Medicare review contractors continue to identify and prevent improper payments due to documentation errors in error-prone claim types, including SNF, hospital outpatient and IRF. HHS will continue to develop and prioritize additional CAPs in FY 2026 based on the FY 2025 improper payment rate data.

Additional information
The Reporting Year (RY) 2025 Medicare Fee-for-Service (FFS) improper payment rate is statistically lower than the RY 2024 Medicare FFS improper payment rate.
Reduction target
6.45 %A tolerable rate has not been established for this program. The tolerable rate will be identified when the methodology is developed. Once the tolerable rate is developed, the agency can determine if we have what is needed with respect to internal controls, human capital and information system and other infrastructure to reduce Improper Payments and Unknown Payments to the tolerable rate.
To establish and maintain payment integrity internal controls in HHS included the following program integrity proposals in its FY 2027 Budget request:
• Share Information on Providers Subject to a Medicare Payment Suspension with • Supplemental Payers and Hold Beneficiaries Harmless
• Expand PA for Excessively Ordered Services
• Expand Prior Authorization to Medicare FFS Home Health Services
• Allow ordering providers to submit PA requests for FFS
• Established Authority to Reject a DME Supplier Surety Bond if the Surety Failed to Make a Prior Required Payment(s) to CMS
The agency's internal controls to detect, prevent, and recover improper payments are reported annually in the AFR. In addition, the agency sets annual performance goals related to the improper payment rates and reports quarterly on specific corrective actions to address improper payment rates through the quarterly scorecard process for high-priority programs.
