Which factor does NOT contribute to Wellcare's Star Ratings?

The correct choice highlights that enrollment numbers do not directly impact Wellcare's Star Ratings. Wellcare’s Star Ratings are primarily based on quality measures related to the care and services provided to members, rather than simply how many members are enrolled or a measure of popularity.

Star Ratings focus on specific metrics such as member experience, clinical quality, and outcomes. This includes factors like member complaints, which reflect the satisfaction and perceived quality of service, and member experience, which encompasses various aspects of how members feel about their interactions with the healthcare system. Rapid disenrollment can also indicate issues within the service that affect overall satisfaction and quality scores.

In essence, the Star Ratings aim to evaluate the quality of care and beneficiary satisfaction rather than just the size of the member base. Thus, while enrollment is crucial for operational success, it does not play a role in calculating the Star Ratings.
