This article breaks down the key findings of the 2025 Medicare Star Ratings, released by CMS, and explains how this information can empower you to compare Medicare Rx plans effectively. We’ll delve into what these ratings mean, how they are calculated, and what the latest data reveals about the quality of Medicare plans in 2025. By understanding these ratings, you can confidently navigate the complexities of Medicare Part D and choose a plan that offers both high-quality care and comprehensive prescription drug coverage.
Decoding Medicare Star Ratings: A Key to Compare Medicare Rx Plans
The Medicare Star Ratings system is designed to empower Medicare beneficiaries to compare Medicare Rx plans and Medicare Advantage plans based on quality and performance. CMS assigns star ratings from 1 to 5 stars, with 5 stars representing the highest quality. These ratings are based on dozens of performance measures that cover various aspects of plan quality, including:
- Quality of Care: Measures related to preventive care, chronic condition management, and treatment effectiveness.
- Customer Service: Experiences with plan customer service, including call center responsiveness and handling of complaints.
- Member Experience: Overall satisfaction of plan members, gauged through surveys and feedback.
- Drug Safety and Accuracy: Measures related to medication safety, accuracy of drug pricing, and appropriate medication use.
For those looking to compare Medicare Rx plans specifically, the Part D Star Ratings are most relevant. These ratings focus on stand-alone Prescription Drug Plans (PDPs) and the prescription drug coverage offered within Medicare Advantage Prescription Drug (MA-PD) plans. By examining these ratings, you can gain insights into how well different plans perform in areas critical to your prescription drug needs.
Key Highlights from the 2025 Star Ratings: What’s New for Comparing Rx Plans?
The 2025 Star Ratings reveal important trends and changes that can influence your decision when you compare Medicare Rx plans. While there were no major methodological overhauls this year, some adjustments and performance shifts are noteworthy:
Stable Overall Quality for Medicare Advantage, Slight Dip in Top Ratings
While a significant portion of Medicare Advantage Prescription Drug (MA-PD) contracts maintain strong ratings, the very top tier of 5-star plans has seen a decrease.
- Approximately 40% of MA-PD plans for 2025 achieved 4 stars or higher, indicating a continued commitment to quality across a large segment of the market.
- However, the percentage of MA-PD contracts achieving the coveted 5-star rating decreased significantly from previous years. In 2025, only 1.34% of contracts earned 5 stars, compared to 6.97% in 2024 and much higher percentages in prior years (See Table 1).
- Despite the drop in 5-star plans, a substantial 62% of MA-PD enrollees are in plans rated 4 stars or higher, suggesting that a majority of beneficiaries still have access to high-quality MA-PD options.
This shift highlights the importance of looking beyond just the top rating and considering the broader landscape of 4-star and above plans when you compare Medicare Rx plans within MA-PD offerings.
Part D Plan Ratings: Focus on 4-Star and Above When Comparing Rx Plans
For stand-alone Part D plans (PDPs), the distribution of star ratings presents a different picture.
- Around 27% of PDPs achieved 4 stars or higher for 2025.
- Similar to MA-PDs, the 5-star rating remains rare for stand-alone PDPs, with only 4.88% of contracts achieving this top score.
- Enrollment in higher-rated PDPs is relatively low. Only about 5% of PDP enrollees are in plans rated 4 stars or higher.
This data emphasizes the importance of carefully comparing Medicare Rx plans, particularly stand-alone PDPs, and potentially focusing your search on those achieving 4 stars or higher to ensure a higher quality experience.
Methodological Changes: Minor Tweaks, Consistent Quality Focus
CMS continuously refines the Star Ratings methodology to ensure accuracy and drive quality improvement. For 2025, minor adjustments include:
- Increased Weight for Readmissions Measure: The Part C Plan All-Cause Readmissions measure now carries a higher weight, reflecting CMS’s focus on reducing hospital readmissions and improving care transitions.
- Guardrails for Medicare Plan Finder Measure: The Part D Medicare Plan Finder measure, which assesses the accuracy of plan information on the Medicare Plan Finder tool, now has bi-directional guardrails applied to ensure stability and prevent drastic year-over-year changes in cut points.
These methodological refinements underscore CMS’s ongoing commitment to strengthening the Star Ratings program and providing meaningful quality data to help beneficiaries compare Medicare Rx plans and MA plans effectively.
Digging Deeper: Factors Influencing Star Ratings and Plan Comparison
Beyond the overall distribution of ratings, the 2025 Star Ratings data reveals interesting trends related to plan characteristics and performance. These insights can further refine your approach when you compare Medicare Rx plans.
Tax Status Matters: Non-profit Plans Tend to Score Higher
The data indicates a correlation between a plan’s tax status and its Star Rating performance.
- Non-profit organizations more frequently achieve higher ratings than for-profit organizations, both for MA-PDs and PDPs.
- Approximately 50% of non-profit MA-PD contracts received 4 or more stars, compared to 36% of for-profit MA-PDs.
- Similarly, for PDPs, around 41% of non-profit PDPs reached the 4-star or higher benchmark, while only 17% of for-profit PDPs did so.
While tax status is not the sole determinant of plan quality, this trend suggests that when you compare Medicare Rx plans, considering the tax status of the plan provider might offer an additional layer of insight.
Experience Counts: Established Plans Often Perform Better
Longevity in the Medicare program appears to be linked to higher Star Ratings, particularly for MA-PD contracts.
- MA-PDs with 10 or more years in the program are more likely to achieve 4 or more stars compared to newer plans.
- This suggests that more established plans may have refined their processes and quality improvement initiatives over time, leading to better performance.
For PDPs, the relationship is less clear due to fewer PDPs being newer to the program. However, the general trend suggests that when you compare Medicare Rx plans, considering the plan’s experience in the Medicare program could be a valuable factor.
Using Star Ratings to Compare Medicare Rx Plans: A Practical Guide
The 2025 Medicare Star Ratings provide a powerful tool for anyone looking to compare Medicare Rx plans. Here’s how you can utilize this information to make informed choices:
-
Identify Your Needs: Before you start comparing plans, understand your prescription drug needs. Consider the medications you take regularly, your preferred pharmacy, and any specific coverage requirements.
-
Utilize the Medicare Plan Finder: The Medicare Plan Finder tool on Medicare.gov is your primary resource for comparing plans. This tool integrates the Star Ratings directly into plan listings, making it easy to see how different plans are rated.
-
Focus on 4-Star and 5-Star Plans: While 5-star plans are exceptional, expanding your search to include 4-star plans will significantly increase your options. These plans also represent high-quality choices when you compare Medicare Rx plans.
-
Consider Plan Type: Decide whether you need a stand-alone Part D plan or if a Medicare Advantage Prescription Drug plan better suits your overall healthcare needs. Compare ratings within each plan type separately.
-
Look Beyond Star Ratings: While Star Ratings are crucial, also consider other factors like:
- Premiums and Costs: Compare monthly premiums, deductibles, copays, and coinsurance.
- Formulary (Drug List): Ensure your essential medications are covered on the plan’s formulary and at a favorable cost tier.
- Pharmacy Network: Check if your preferred pharmacies are in the plan’s network.
- Extra Benefits: Some plans offer additional benefits like vision, dental, or wellness programs.
-
Review Measure-Level Ratings: For a deeper dive, explore the measure-level ratings for specific plans. This can provide insights into their performance on particular aspects of care, such as customer service or medication adherence. (Tables 7, 8, and 9 in the original document provide average measure-level ratings).
-
Pay Attention to Low-Performing Icons: Be aware of plans with the “low-performing icon.” These plans have consistently low ratings and may signal areas of concern. (Table A4 in the Appendix lists low-performing contracts).
-
Enroll During Open Enrollment: Medicare Open Enrollment, from October 15 to December 7 each year, is the primary time to enroll in or change Medicare plans for the following year. Use this period to compare Medicare Rx plans and make your selection for the upcoming year.
