Medigap Premium Surge Timeline
Carriers implemented average 9.8% increases in 2024, with nearly half enacting double-digit hikes up to 20%, according to AAMSI’s June 2024 report.
Pre-2024 saw predictable 3-5% annual rises for stable carriers and 5-7% for popular Plans G and F. Continued spikes hit 2024-2025, including 50-70% in closed-block plans without new enrollees. Increases ties to enrollment anniversaries, catching policyholders off guard each year.

Closed blocks, like post-2020 Plan F, age riskier without younger entrants, fueling massive jumps. Brokers report stability vanished, urging annual checks. Healthy seniors switch carriers whenever possible, but future health barriers loom large, worsening the cycle.
Three Pricing Models Drive Inevitable Rises
Federal rules standardized Medigap since 1990 to cover Original Medicare gaps like copays and deductibles. Attained-age pricing raises premiums as policyholders age. Issue-age fixes rates at enrollment but adjusts for inflation.
Community-rated charges uniform premiums sensitive to overall claims and inflation. All models respond to healthcare costs, but attained age proves to be the most volatile long-term.
Mutual of Omaha starts competitively but escalates higher over time. AARP/UnitedHealthcare offers predictability. Cigna maintains stability with state adjustments.
Humana lures with low intros but hikes later. Aetna provides household discounts. Carriers’ file rates based on experience are approved by states and the NAIC.
Stakeholders Fuel the Premium Spiral
Insurers like UnitedHealthcare set and raise premiums to improve profitability amid rising claims and inflation. Agents prioritize Medicare Advantage for higher commissions, depleting healthy Medigap pools.
Regulators balance protection and profits by approving hikes. Consumers, mostly fixed-income seniors 65+, have low influence and react to anniversary notices. Power tilts to carriers and states.
Surge in Advantage enrollments left Medigap pools riskier. Healthy switches concentrate claims, justifying 10-20% yearly hikes. Agents recommend Medigap only for high-needs cases, prioritizing commissions over consumer stability.
Consumer Traps and Limited Alternatives
Guaranteed renewability keeps policies active, but switches trigger medical underwriting, blocking unhealthy enrollees. Medicare Advantage offers zero premiums, yet lacks Medigap’s nationwide access and requires prior authorizations.
Affects 10-15 million, premiums varying by state from $140 low in New Mexico to $236 high in New York. Fixed incomes face budget strain as costs double faster than they did over the prior 10-year period.
Short-term, out-of-pocket jumps to a yearly average of $2,600. Long-term, spirals entrench high costs, boosting Advantage shifts. Rural and high-cost states suffer most.
Political calls for rate caps emerge, but regulation must preserve choice without stifling markets—principles demand accountability over overreach.
