Overpayments to Medicare Advantage Plans: An Analysis

A recent analysis by Republican members of the Joint Economic Committee highlights a pressing issue concerning overpayments to Medicare Advantage plans and their financial impact on Medicare Part B premiums. The report reveals that Medicare is spending approximately 20% more for individuals in Medicare Advantage compared to traditional Medicare, potentially leading to an $84 billion excess by 2025.

The analysis suggests that aligning Medicare Advantage payments with traditional Medicare could mitigate this issue. This reform could safeguard Social Security benefits for approximately 50 million Part B beneficiaries and potentially save seniors around $2,600 over the next decade.

Medicare Part B covers various outpatient services, including doctor visits and diagnostic tests. Megan O’Reilly, AARP Vice President for Health and Family Issues, underscores the importance of efficient Medicare fund use, particularly amid rising premiums. She states, "We cannot afford waste in the system."

Medicare Advantage receives a fixed monthly payment per beneficiary, differing from traditional Medicare’s service-based model. According to MedPAC, the higher Medicare Advantage payments mainly stem from this structure. However, AHIP spokesperson Chris Bond questions MedPAC's data accuracy and its implications for the 35 million Medicare Advantage beneficiaries.

AARP backs a CMS-proposed rule to address Medicare Advantage upcoding, set for 2027 implementation. The current system incentivizes reporting more diagnoses for higher payments. O’Reilly emphasizes that equitable payment rates are essential for the program’s strength and affordability.

If payment disparities continue, Part B premiums might increase by up to $450 per beneficiary annually by 2035, with recent years already experiencing significant hikes due to overpayments. Since 2016, these overpayments have inflated Medicare Part B premiums by $82 billion.

The overall financial health of Medicare remains concerning. The Medicare Board of Trustees warns that by 2033, the trust fund may not fully cover hospital inpatient costs, exacerbated by demographic shifts, increasing service demand, and inflation. With Medicare Advantage now serving over half of Medicare beneficiaries, AARP advocates for reforms to ensure Medicare's future viability and to minimize premium burdens on beneficiaries.
