Evaluations & Research Reports
All CMS Innovation Center Models are rigorously and independently evaluated. Best practices and lessons learned from evaluation reports are often used to inform the next iterations of model tests.

September 2025
Findings for this report mostly align with earlier reports, suggesting the RCHD has reached a steady state in its financial impact and has achieved its goal of offering a mechanism for improved financial viability for RCH hospitals. In aggregate, hospitals new to the Demonstration saw an improvement in their Medicare inpatient margins while continuing hospitals maintained inpatient margins near a break-even point during the CCA extension. The COVID-19 pandemic dampened these effects, particularly for new participants.Read more
Enhancing Oncology Model Evaluation of Performance Period 1 (July–December 2023)
August 2025
The Enhancing Oncology Model (EOM) is an episode-based payment model where participants are financially accountable for the total cost of a 6-month episode of care involving systemic cancer therapies. In the first performance period, episodes starting between July to December 2023, practices reported a focus on value-based pharmacy interventions, which may have driven reductions in Part B cancer therapy spending and payment reductions. After accounting for payments to participants, estimates suggest net losses to Medicare.Read more
End-Stage Renal Disease Treatment Choices (ETC) Model 3rd Annual Evaluation Report (PDF)
August 2025
Through three performance years (2021-2023), the End Stage Renal Disease (ESRD) Treatment Choices (ETC) Model has led to an increase in home dialysis training and an increase in overall transplant rates, driven by an increase in deceased donor transplants. The ETC Model has not led to increased home dialysis rates, transplant waitlisting, or transplant rates. ETC has had no impacts on overall Medicare spending nor on quality of care for patients on dialysis. The ETC Model is proposed to end December 31, 2025.Read more
Maternal Opioid Misuse (MOM) Model - Fourth Annual Evaluation Report (PDF)
July 2025
The Maternal Opioid Misuse (MOM) Model provides integrated care for pregnant/postpartum Medicaid beneficiaries with OUD. Through the third year of implementation, seven states engaged 2,119 patients using peer recovery services, provider communication improvements, and Health Related Social Needs resource connections. As the MOM Model ends in December 2025, states are designing sustainable funding and expanding access by broadening populations served, opening new clinics, and training providers.Read more
Primary Care First Model Options - Third Evaluation Report
May 2025
In its third performance year, PCF had no meaningful effect on hospitalizations and an increase in Medicare expenditures, as expected at this point in the model. Practices remained engaged in the model and continued to implement, and often modified existing care delivery strategies, especially care management, and added new strategies focused on comprehensiveness of and access to care.Read more
Preview of Findings from the Evaluation of ACO REACH Model for Performance Year 2023
May 2025
This document comprises a summary of performance year (PY) 2023 findings that will be included in the forthcoming evaluation report for ACO REACH. This report offers evaluation findings that informed the PY 2026 model design changes for ACO REACH. Building on the evaluation findings from the Global and Professional Direct Contracting Model in PY 2022, this summary of the forthcoming evaluation report indicates increased net spending associated with the ACO REACH Model cumulatively, although the PY 2023 results also show signs trending in a positive direction overall for gross savings, quality, and utilization measures.Read more
May 2025
The Kidney Care Choices (KCC) Model includes two model options: the Kidney Care First (KCF) option primarily uses payment adjustments, and the Comprehensive Kidney Care Contracting (CKCC) option is a total cost of care model with varying levels of risk. Results from the second year (PY2023) of the KCC Model continued to show significant improvements in key quality goals of the model, such as increased rates of home dialysis and home dialysis training, increased optimal starts to dialysis, and increased preemptive and living donor transplants. Despite these quality gains, the model resulted in a significant net loss to Medicare in PY2023.Read more
BPCI Advanced Sixth Annual Report
April 2025
The BPCI Advanced Model produced savings of $346 million in Model Year 5 (2022), driven largely by decreases in post-acute care spending. This finding continues the pattern of savings in Model Year 4 (2021), after CMS made changes to the model that were designed to increase the likelihood of savings to Medicare following losses in Model Years 1-3. This report describes how participants achieved savings while maintaining quality on claims-based outcomes (readmissions and mortality), but identifies room for improvement in patient-reported care experiences and satisfaction.

Independence at Home: Year Nine Evaluation Report
March 2025
The Independence at Home (IAH) Demonstration was launched in 2012 through Section 3024 of the Patient Protection and Affordable Care Act. Under the demonstration, physician- and nurse-led teams provide primary care services in the homes of beneficiaries with chronic illness and functional limitations. IAH practices receive a payment incentive if they generate savings above an established threshold and meet quality-of-care targets. This evaluation report covers the first nine years of the demonstration and examines the IAH incentive payment’s effects on spending, utilization, and quality during 2022, the third year of the COVID-19 pandemic.Read more
Medicare Advantage Value-Based Insurance Design Model Evaluation Report: 2020 to 2023 (PDF)
March 2025
Participation in VBID General has increased substantially since Phase II of the model test began, in part due to statutory expansion of the model nationwide and opening participation to special needs plans. Reduced cost sharing for Part D and supplemental benefits dominated VBID General offerings in 2023. VBID General is associated with increases in beneficiary drug adherence, risk scores, and inpatient stays in 2020 and 2021, and Star Ratings and costs to CMS in 2021 and 2022. VBID Hospice participation continued to grow, but uptake of model services continued to be low in 2023.Read more

CMS Data CompendiumThe CMS Office of Information Products and Data Analytics produces an annual CMS Data Compendium to provide key statistics about CMS programs and national health care expenditures. The CMS Data Compendium contains historic, current, and projected data on Medicare enrollment and Medicaid recipients, expenditures, and utilization. Data pertaining to budget, administrative and operating costs, individual income, financing, and health care providers and suppliers are also included. National health expenditure data not specific to the Medicare or Medicaid programs is also included making the CMS Data Compendium one of the most comprehensive sources of information available on U.S. health care finance. This CMS report is published annually in electronic form and is available for each year from 2002 through present.Read more
