Why Your Medicare Premiums Are $200 Higher Than They Should Be

Why It Matters

The inflated premiums erode retirees’ fixed incomes and increase the federal deficit, pressuring policymakers to overhaul Medicare Advantage payment structures.

Key Takeaways

• Medicare Advantage overpays by ~20% versus Original Medicare
• Overpayments add $212 to each Part B premium, $13.4B total
• Upcoding and favorable selection drive the excess payments
• High‑penetration states subsidize low‑penetration states via premiums
• Projected surcharge could reach $450 by 2035 without reform

Pulse Analysis

Medicare Advantage was originally marketed as a cost‑saving alternative, offering extra benefits while reducing government spending. In practice, insurers have leveraged risk‑adjustment formulas, inflating diagnosis codes to secure higher reimbursements—a practice known as upcoding. Coupled with favorable selection, where healthier beneficiaries enroll in private plans, the payment benchmarks become misaligned, resulting in payments roughly one‑fifth above what Original Medicare would cost for the same services. This systemic overpayment creates a hidden subsidy that flows through the Part B premium structure, affecting every Medicare enrollee regardless of plan choice.

The premium pass‑through mechanism means that the $212 average increase per beneficiary is deducted directly from Social Security checks, shrinking retirees’ take‑home pay. While the surcharge is uniform nationwide, its fiscal impact is uneven: states with high Medicare Advantage enrollment, such as Florida and Michigan, effectively receive the benefits of the overpayments, while low‑enrollment states like Wyoming and Alaska fund them. This geographic redistribution intensifies regional equity concerns and adds pressure on the Supplemental Medical Insurance trust fund, which already relies on general revenues and beneficiary contributions.

Policymakers face a choice between tightening oversight of coding practices and redesigning the risk‑adjustment methodology to reflect true cost differentials. Recent DOJ actions, including Kaiser Permanente’s $556 million settlement, signal heightened enforcement against fraudulent billing. Legislative proposals aim to align private plan payments with Original Medicare benchmarks, which could curb the projected $450 surcharge by 2035. For seniors on fixed incomes, such reforms are essential to preserve the purchasing power of Social Security benefits and ensure the long‑term sustainability of the Medicare program.
