Medicare Advantage Overpayments Impacting Part B Premiums
A recent investigation by congressional staffers has revealed that increased payments in Medicare Advantage (MA) are driving up Medicare Part B premiums. These premiums have surged by over $200 per member, resulting in an additional $13.4 billion in spending. Established in the late 1990s, Medicare Advantage was designed to benefit both taxpayers and recipients by encouraging private insurers to limit unnecessary medical care through a fixed payment model.
Medicare Advantage's popularity has grown, now covering more than half of Medicare enrollees. However, the program's costs are approximately 20% higher than traditional Medicare, according to the Medicare Payment Advisory Commission (MedPAC). This additional expense affects not only MA members but also state and federal taxpayers, inadvertently raising costs for traditional Medicare plans.
MedPAC's analysis shows that since 2016, these overpayments have contributed to an $82 billion increase in premiums for Part B services, which include outpatient visits and medical tests. Traditional Medicare beneficiaries have shouldered about $6 billion of this increase through higher premiums. The Joint Economic Committee (JEC) projects that without change, per-person premiums could double over the next decade, with $450 of this increase stemming from excess payments if trends continue.
Calls for Policy Change and Fair Pricing
The JEC report, crafted by the committee's Republican staff, emphasizes the need for better alignment of Medicare Advantage payments with traditional Medicare. JEC Chairman David Schweikert expressed concerns over the impact of these overpayments on seniors' Part B premiums, urging for equitable rules across Medicare platforms.
A significant issue identified is the billing practices of insurers under the MA program. With a structure that compensates insurers more for sicker members, there is an incentive to overreport health conditions, increasing costs relative to traditional Medicare, as outlined by MedPAC. The Centers for Medicare & Medicaid Services (CMS) has proposed changes to payment rules to address these issues, aiming for implementation in 2027.
The insurance industry has opposed these proposed changes, arguing they could lead to reduced benefits for seniors. Nonetheless, CMS plans to enhance audits of MA plans and bolster its medical coding workforce to address backlog issues, with finalization of updated rates anticipated in April. Sen. Chuck Grassley has indicated potential legislation targeting controversial practices by pharmacy benefit managers (PBMs), signaling continued consideration for Medicare reforms.
