ACO Churn Metrics

Describe what % of an ACO beneficiary list turns over year to year.

• Percent moving to a different ACO

• Percent deceased

• Percent staying in the same ACO

• Percent new beneficiaries in their first ACO

• Percent beneficiaries moving from another ACO

Would love to check for correlations between bene churn and performance indicators (cost, readmission, etc.) to see if more stable ACO beneficiary lists translate to more stable performance metrics.

Describe what % of an ACO provider list turns over year to year:

• percent of legal business names (TINs) staying

• percent of individual physicians actually filing claims on behalf of members (using a participating TIN)

• percent of TINs that drop out of ACO membership altogether

• percent of TINs that move to a different ACO
