Medigap Premiums Leap, and Consumers Have Few Alternatives

Why It Matters

Rising Medigap costs threaten seniors’ financial security and could push them toward less flexible Medicare Advantage plans, reshaping the supplemental market and prompting policy debates on federal caps.

Key Takeaways

• Chubb raised Medigap premiums 45% for 80+ clients in August
• Plan G rates jumped 12‑26% Q1 2026 across major insurers
• Over 12 million Americans (≈43%) rely on Medigap, facing higher costs
• State “birthday rule” protections limit seniors’ ability to switch plans
• Congressional out‑of‑pocket caps face budget hurdles amid rising premiums

Pulse Analysis

The latest wave of Medigap premium hikes reflects a confluence of demographic and cost pressures. Actuarial data from Telos shows Plan G rates rising 12%‑26% in the first quarter of 2026, driven by higher claims utilization, an aging enrollee base, and escalating labor and medical expenses. Insurers such as Aetna, Blue Cross Blue Shield, Cigna, Humana, Mutual of Omaha and UnitedHealthcare have all filed increases, signaling a broader industry shift from the modest 3%‑5% annual adjustments that were once typical.

For seniors, the surge translates into tangible financial strain. With the average Plan G premium hovering around $164 per month in 2023 and likely higher now, a 20% increase adds roughly $33 to monthly out‑of‑pocket costs. About 43% of Medicare beneficiaries rely on these supplemental policies, and the limited ability to switch plans—restricted by federal enrollment windows and state‑specific “birthday rule” protections—means many are locked into higher‑priced contracts. Consequently, some retirees are gravitating toward Medicare Advantage plans that cap out‑of‑pocket expenses, even though those plans impose network constraints and may affect future Medigap eligibility.

Policymakers face mounting pressure to address the affordability gap. Proposals range from instituting a federal out‑of‑pocket cap for traditional Medicare to subsidizing Medigap purchases for low‑income seniors. However, any legislative fix must navigate a tight budget environment and partisan gridlock. In the interim, brokers are advising clients to consider deductible‑bearing Medigap options, which lower monthly premiums at the cost of a roughly $3,000 annual deductible, or to explore states with more permissive switching rules. The trajectory of premium growth will likely continue unless systemic reforms curb claim costs or provide direct financial relief to beneficiaries.
