Congress Investigates Medicare Advantage

July 31, 2025

In late July 2025, a joint hearing of the House Ways & Means Health and Oversight Subcommittees brought renewed national attention to the Medicare Advantage (MA) program. Titled “Medicare Advantage: Past Lessons, Present Insights, Future Opportunities,” the hearing unpacked growing concerns about transparency, access, and oversight in a program that now covers over 54% of Medicare beneficiaries.

This blog post breaks down what was discussed, why it matters, and what it means for your healthcare choices moving forward.

The Good: Why Medicare Advantage Remains Popular

Despite growing scrutiny, many lawmakers and stakeholders acknowledged the continued value of Medicare Advantage. Over 95% of beneficiaries report satisfaction with their plan, and MA enrollment continues to rise—especially among rural residents and underserved communities.

Why the popularity? Lower premiums, additional benefits like dental and vision, fitness perks, transportation coverage, and care coordination are often included—offering a bundle of value not found in Original Medicare alone.

The Concern: Prior Authorization and Delayed Care

However, the hearing focused heavily on prior authorization—an administrative hurdle that MA plans use to approve or deny services before they are delivered. While the intent is cost control, delays can significantly impact care quality.

The American Hospital Association (AHA) and American Medical Association (AMA) testified that:

  • 93% of physicians report delays due to prior auth.

  • 82% say patients sometimes abandon treatment because of delays.

  • There is no national standard or transparency for denial rates among MA plans.

Lawmakers from both parties expressed concern that patients are waiting too long for medically necessary care.

The Cost Issue: Upcoding and Overpayments

Another central issue was “upcoding”—a practice in which insurers classify patients as sicker than they are, leading to higher reimbursements from the government. MedPAC estimates that Medicare Advantage costs taxpayers $84 billion more annually than if those same beneficiaries were in traditional Medicare.

In addition, questions were raised about the lack of transparency surrounding how MA plans spend their federal rebates—over $66 billion in 2025 alone. Much of that money is allocated to supplemental benefits, yet there’s little oversight to confirm their value or use.

Stakeholder Responses and Legislative Proposals

Multiple healthcare organizations supported the Improving Seniors’ Timely Access to Care Act (H.R. 3514/S. 1816), which would:

  • Require electronic and standardized prior authorization.

  • Mandate public reporting of prior authorization approval rates.

  • Set time limits for decisions, especially in urgent care cases.

Other proposals included tightening audits on risk adjustment coding and implementing payment parity reforms between MA and traditional Medicare.

What Beneficiaries Should Know (and Do)

Whether you’re already enrolled in an MA plan or considering switching this fall, here are key takeaways:

  • Know your plan’s prior authorization rules: Not all MA plans are equal. Some may require more paperwork or delay access to imaging, therapies, or specialist referrals.

  • Appeal denials: Don’t accept “no” as the final answer—many denials are overturned on appeal.

  • Check provider networks regularly: MA networks can change during the year.

  • Review your Annual Notice of Changes (ANOC): Watch for policy or benefit changes this fall.

  • Ask your agent: Discuss plans with higher transparency or those participating in pilot reforms.

What’s Next?

This hearing represents a pivotal moment. Lawmakers are recognizing the need to rebalance oversight and benefits within Medicare Advantage. With bipartisan attention on prior authorization reform and payment audits, future legislative updates could reshape plan operations as early as 2026.

As always, staying informed and reviewing your plan options annually is the best way to ensure your coverage aligns with your health and financial needs.
