What the 2027 Medicare Advantage Proposed Rule Means for Seniors

Federal regulators are proposing meaningful changes to Medicare Advantage and Part D prescription drug plans for 2027 that could affect tens of millions of older Americans. The Bipartisan Policy Center, a respected nonpartisan research organization, has weighed in with detailed recommendations urging CMS to strengthen consumer protections while preserving the flexibility that makes these plans attractive to seniors.

What Is the CMS 2027 Proposed Rule?

Each year, the Centers for Medicare & Medicaid Services issues a proposed rule that sets the ground rules for how Medicare Advantage (MA) and Part D prescription drug plans must operate in the coming plan year. The 2027 proposed rule covers a wide range of topics — from how plans handle prior authorization requests to how supplemental benefits like dental and vision are structured and marketed.

Think of it as an annual policy update that shapes what your Medicare Advantage plan can and cannot do. While the rule is written in regulatory language, its effects are felt directly by the roughly 33 million Americans enrolled in Medicare Advantage plans.

What the Bipartisan Policy Center Is Recommending

Stronger Prior Authorization Protections

One of the BPC's central recommendations involves prior authorization — the process by which a plan must approve certain medical services or medications before you receive them. Critics have long argued that prior authorization can delay or deny necessary care.

The BPC supports CMS proposals that would require plans to respond to prior authorization requests more quickly, improve the appeals process, and increase transparency about which services require approval. For seniors managing chronic conditions or needing specialist care, these changes could reduce frustrating delays in getting treatment.

Tighter Rules on Supplemental Benefits

Medicare Advantage plans are permitted to offer supplemental benefits beyond original Medicare — things like dental cleanings, hearing aids, fitness memberships, and transportation to medical appointments. These extras are often a major selling point during open enrollment.

However, the BPC has raised concerns that some supplemental benefits are poorly defined, inconsistently delivered, or used primarily as marketing tools rather than genuine health supports. The organization recommends that CMS require plans to demonstrate that supplemental benefits are actually used by enrollees and produce measurable health outcomes. This would help ensure that the benefits advertised during open enrollment are ones you can realistically access and use.

Prescription Drug Cost Reforms Under Part D

The 2027 proposed rule also addresses Part D, the prescription drug coverage component of Medicare. Following the Inflation Reduction Act's landmark changes — including a $2,000 annual out-of-pocket cap on drug costs — CMS is working to ensure that plan designs align with the new law's intent.

The BPC supports provisions that would prevent plans from using benefit design strategies that effectively shift costs onto beneficiaries in ways that undermine the cap. For seniors who rely on multiple medications, these protections could make a real difference in monthly budgeting.

Marketing and Enrollment Safeguards

Misleading Medicare Advantage marketing has been a persistent problem. Seniors have reported being enrolled in plans they did not fully understand or being contacted repeatedly by aggressive brokers. The BPC endorses CMS proposals to strengthen marketing standards, including clearer disclosure requirements and tighter rules on how third-party marketing organizations operate.

If finalized, these changes would give seniors better information at the point of enrollment and reduce the risk of being switched into a plan that does not meet their needs.

Oversight of Plan Payments and Star Ratings

Medicare Advantage plans are paid by the federal government based on a complex formula, and they receive quality bonuses tied to a star rating system. The BPC recommends that CMS improve the accuracy of risk adjustment payments — the mechanism that compensates plans for enrolling sicker patients — and refine the star ratings methodology to better reflect actual quality of care.

These are technical but important reforms. More accurate payments reduce incentives for plans to cherry-pick healthier enrollees, and better star ratings help seniors make more informed choices during open enrollment.

What This Means for You Right Now

If you are currently enrolled in a Medicare Advantage or Part D plan, you do not need to take any immediate action. Proposed rules go through a public comment period before being finalized, and the 2027 changes would not take effect until the plan year beginning January 1, 2027.

However, it is worth paying attention to these developments as you approach the Annual Enrollment Period (October 15 – December 7 each year). Changes to plan rules can affect which benefits are available, how prior authorization works, and what your drug costs look like. Staying informed helps you make better decisions when it is time to compare plans.
