 What's the best way to choose a Medicare health plan? That's simple. The Medicare Star Quality Ratings. Medicare plans' star ratings are calculated each year by the Centers for Medicare and Medicaid Services through continuous monitoring and evaluation. Medicare health plans are rated from 1 star to 5 stars, with 5 being excellent. The Medicare Star Quality Ratings are based on major categories that include preventive care, chronic care, prescription drug services, customer service, and member satisfaction.
