Bluestone Accountable Care Organization (ACO)

Bluestone Physician Services is participating in Bluestone ACO, an Accountable Care Organization. An ACO is a group of health care providers that work together to improve the quality and experience of care you receive. ACOs receive a portion of any savings that result from reducing costs and meeting quality requirements. Beneficiaries that are included in this population are those that have fee-for-service Medicare or Original Medicare.

What you need to know

  • Medicare evaluates how well each ACO meets these goals every year. Those ACOs that do a good job can earn a financial bonus. ACOs that earn a bonus may use the payment to invest more in your care or share a portion directly with your providers. ACOs may owe a penalty if their care increases costs.
  • Our participation in the Bluestone ACO doesn’t limit your choice of health care providers. Your Medicare benefits are not changing. You still have the right to visit any doctor, hospital or other provider that accepts Medicare at any time, just like you do now.
  • To help us coordinate your health care better, Medicare shares information about your care with your providers. If you wish to decline this sharing of information call 1-800-MEDICARE (1-800-633-4227).

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 of 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.
