Understanding the 2027 Medicare Star Quality Ratings


Understanding the Medicare Star Quality Ratings - 2027



Each year, Medicare measures Medicare plans using various measures. An overall star rating is calculated for each plan. A summary rating of prescription drug plan quality and a separate summary rating of health plan quality are calculated where appropriate.

This section explains how the star ratings are calculated and provides examples of plan quality.



For plans covering health services and no prescription drug coverage (MAs), the overall score for quality is the same as the summary rating of health plan quality.

For plans covering only prescription drugs and no health services (PDPs), the overall score for quality is the same as the summary rating of drug plan quality.

For plans covering both health services and prescription drug coverage (MAPds), the overall score for quality calculated from the underlying topics from both the health plan summary and the drug plan summary.




Overall Star Rating

The Overall Star Rating is used to determine if a Medicare plan qualifies for the 5-Star Special Enrollment Period or if the Medicare plan falls into the consistently low performing Special Enrollment Period.

The Overall Star Rating combines scores for the types of services each plan offers: What is being measured?
