Our ACO was affected by an Extreme and Uncontrollable Circumstance (EUC) in PY 2024 and was unable to report all of the quality measures for PY 2024

For Previous Years’ Financial and Quality Performance Results, Please Visit data.cms.gov

*For Diabetes: Hemoglobin A1c (HbA1c) Poor Control (>9%) [Quality ID #001], Hospital-Wide, 30-Day, All-Cause Unplanned Readmission (HWR) Rate for MIPS Eligible Clinician Groups [Measure #479], and Clinician and Clinician Group Risk-standardized Hospital Admission Rates for Patients with Multiple Chronic Conditions (MCC) [Measure #484], a lower performance rate indicates better measure performance.

*For Clinician and Clinician Group Risk-standardized Hospital Admission Rates for Patients with Multiple Chronic Conditions (MCC) [Measure #484], patients are excluded if they were attributed to Qualifying Alternative Payment Model (APM) Participants (QPs). Most providers participating in Track E and ENHANCED track ACOs are QPs, and so performance rates for Track E and ENHANCED track ACOs may not be representative of the care provided by these ACOs' providers overall. Additionally, many of these ACOs do not have a performance rate calculated due to not meeting the minimum of 18 beneficiaries attributed to non-QP providers.

Payment Rule Waivers:

  • Skilled Nursing Facility (SNF) 3-Day Rule Waiver: 
    • Our ACO uses the SNF 3-Day Rule Waiver, pursuant to 42 CFR § 425.612.
