Please note, the ACO-40 Depression Remission at 12 months quality measure is not included in public reporting due to low sample size. The Centers for Medicare & Medicaid Services (CMS) also waived the requirement for ACOs to field a CAHPS for ACOs survey for PY 2020 through the Physician Fee Schedule Final Rule for Calendar Year 2021. Additionally, CMS reverted ACO-8 Risk-Standardized, All Condition Readmission and ACO-38 Risk- Standardized Acute Admission Rates for Patients with Multiple Chronic Conditions to pay-for-reporting, given the impact of the coronavirus disease 2019 (COVID-19) public health emergency (PHE) on these measures
