Definitions of 'Attributed' and 'Assigned' Patients

Problem

How does CMS define the terms 'Attributed' and 'Assigned' when referring to patients? Is this definition different in the Health Endeavors database?

Solution

On the definition of 'Attributed' patients, both CMS and Health Endeavors define a patient this way when the patient is attributed to an ACO.

On the definition of 'Assigned' patients:

• CMS' definition for Assigned is identical to their definition of Attributed.
• Health Endeavors' definition of Assigned refers to whether or not the patient has been assigned to a practice and provider.
