The Medicare Advantage Quality Bonus Program: A Costly Incentive
The Rising Cost of Quality
The Medicare Advantage Quality Bonus Program, a brainchild of the Affordable Care Act, has become a significant expense, with projected spending surpassing $13 billion in 2026. This program, designed to enhance Medicare payments to high-performing Medicare Advantage plans, has seen its budget balloon over the years, starting from a mere $3 billion in 2015.
What's intriguing is the program's incentive structure. Plans with a star rating of 4 or above on a 5-star scale are eligible for increased payments, which they can use to offer supplemental benefits like reduced cost-sharing, extra services, or lower premiums. However, the criteria for these star ratings are complex and have faced criticism.
A Complex Rating System
The star ratings, meant to guide consumers in choosing plans, are based on numerous measures, from cancer screening rates to customer service. But here's the catch: these ratings are assigned at the contract level, not the plan level. This means that a single contract with multiple plans can have varying benefits, costs, and service areas, making it challenging for consumers to make informed decisions.
The Medicare Payment Advisory Commission (MedPAC) and other experts argue that these ratings are too intricate and fail to consider social risk factors, potentially misleading consumers about plan quality. This complexity has led to calls for reform or even the program's elimination, with estimates suggesting significant federal savings if it were discontinued.
The Impact on Enrollment and Spending
The program's influence on enrollment and spending is noteworthy. In 2026, nearly 24 million people, or 68% of Medicare Advantage enrollees, were in plans eligible for higher payments under the bonus program. This is a substantial increase from 2015, indicating the program's growing reach.
However, the impact on spending is even more striking. Medicare Advantage benchmarks and spending have outpaced traditional Medicare, partly due to the quality bonus program. This program, combined with higher coding intensity and favorable selection in Medicare Advantage, adds a staggering $76 billion to Medicare spending in 2026.
The Role of Star Ratings
The star ratings system, while intended to encourage quality improvement, has become a contentious issue. Recent changes by the Centers for Medicare & Medicaid Services (CMS) to simplify the ratings have inadvertently increased spending. This is because more plans now qualify for payment increases, highlighting the delicate balance between incentivizing quality and controlling costs.
Disparities in Plan Performance
Intriguingly, employer- and union-sponsored plans have consistently performed better, with higher average star ratings and a larger share of enrollees receiving bonus-eligible coverage. This raises questions about the benefits offered by these plans and whether they are more generous than others. However, data gaps make it challenging to draw definitive conclusions.
On the other hand, special needs plans, which serve higher-need beneficiaries, often receive lower star ratings, prompting concerns about the quality of care they provide. This disparity in ratings across plan types underscores the complexity of assessing and rewarding quality in the Medicare Advantage landscape.
The Bottom Line
The Medicare Advantage Quality Bonus Program, while well-intentioned, has evolved into a costly endeavor with a complex rating system. Its impact on enrollment and spending is significant, but it also highlights the challenges of balancing quality incentives with fiscal responsibility. As the program continues to evolve, policymakers must carefully consider its design to ensure it serves Medicare beneficiaries effectively without straining the system's finances.
