Medicare Star Ratings: The Revenue-Defining Changes You Must Act on Now
Key Takeaways
• The Great Re-Weighting is Here: Contrary to common belief, the weight of Patient Experience (CAHPS) and Access measures is decreasing from 4x to 2x for the 2026 Star Ratings. This fundamentally alters strategy, making the remaining high-weight measures more critical than ever.
• The Financial Stakes Are Clear: With a $12.7 billion Quality Bonus Program (QBP) pool, the path to a 4-Star or higher rating is now narrower and runs directly through the metrics you can control, like medication adherence.
• Adherence is the New Center of Gravity: As other measures decrease in influence, the triple-weighted Medication Adherence (PDC) scores have become the single most important, controllable lever for protecting your Star Rating and your revenue.
See how one health plan leveraged the increased importance of medication adherence to achieve significant PDC improvements and protect millions in bonus payments.

A strong adherence program for these members is now a core financial strategy.
The final 2025 Medicare Star Ratings results are in, and for health plan leaders across the country, the message from CMS is crystal clear: the ground has shifted beneath our feet. The strategies that secured high ratings in the past are no longer sufficient.
Navigating these changes is a high-stakes challenge. With $12.7 billion in Quality Bonus Payments on the line, understanding the new rules is essential. This isn't just a summary of those changes. This is an urgent call to action and a strategic playbook for protecting your revenue.

What Really Changed? The Three Shifts Defining the New Reality
Three major shifts have created a new, more challenging environment for health plans.
The Great Re-Weighting: For years, plans have focused heavily on Patient Experience (CAHPS) and Access measures. But for the 2026 Stars year, CMS has cut their weight in half, from 4x to 2x. This is the single most important strategic change to understand. The influence of these survey-based measures has been significantly reduced.
The End of "Easy" Wins: Volatile "cut points" are being stabilized by statistical methods like the controversial Tukey outlier deletion. This change makes it much harder to achieve a high rating with small, incremental improvements. Sustained, high-level performance is now the only path to the top.
The New Equity Imperative: The old Reward Factor is gone. In its place for the 2027 Stars year is the Health Equity Index (HEI). This now directly rewards plans for improving care for members with social risk factors (like LIS/DE). Excelling with your vulnerable populations is no longer just a mission—it's a core financial driver.

Where to Focus Now: Adherence is the New Center of Gravity
With the "re-weighting" reducing the impact of CAHPS and Access, your strategy must pivot to the measures that remain stable and highly controllable.
This puts the three triple-weighted Medication Adherence (PDC) measures for Diabetes, Hypertension (RAS), and Statins squarely in the spotlight. For a detailed breakdown of adherence strategy, see our PDC Improvement Guide.
At Rivvi, we believe that a drop in medication adherence is a distress signal. It's often the first sign of a larger issue—a transportation barrier, a new financial strain, or confusion about a care plan.
You cannot fix a problem you don't understand. A generic refill reminder can't solve a transportation issue, and that is why the old playbook for adherence is failing.
Your Action Plan for 2026 and Beyond
Awaiting next year's results is not a strategy. The time to act is now.
Treat Equity as a Core Financial Strategy: The HEI is your new roadmap. Focus your resources on understanding and resolving the barriers faced by your most vulnerable members. This is now the most direct path to improving both your HEI score and your triple-weighted adherence measures simultaneously.
Target Adherence with Surgical Precision: The old way of sending generic reminders is destined to fail. In a recent pilot, we found that 27% of a plan's member phone numbers were invalid—a foundational barrier to adherence that most platforms miss. You must have a scalable way to have real, two-way conversations to uncover the true barriers. Our platform is designed for this, achieving an 89% interaction completion rate with this exact member population.
Use Proactive Outreach to Inform Member Experience: While the weight of CAHPS is down, member experience is still vital. A positive survey result is the outcome of a full year of positive interactions. By regularly engaging members to solve their real-world problems—like scheduling appointments or clarifying benefits—you build the trust and positive sentiment that will still be reflected when it's time for them to answer their survey.

The Future of Star Ratings is Proactive Partnership
The era of chasing fluctuating cut points is over. The future belongs to health plans that build genuine, proactive, and equitable partnerships with their members. The plans that win in 2026 and beyond will be the ones that use technology not just to remind, but to listen, understand, and resolve.
