Story Snapshot
- Chubb’s unprecedented 45% immediate hike affected 80+ customers, defying 49-year broker norms.
- Double-digit increases now standard across carriers like Aetna, Humana, and UnitedHealthcare for 2026.
- 12-14.6 million enrollees face eroding budgets as medical costs and an aging Boomer population drive costs skyward.

- Brokers urge shopping carriers and plans amid normalized 10-26% annual jumps.
Chubb’s Sudden 45% Premium Shock in August 2025
Chubb insurer raised Medigap premiums by 45% effective immediately on existing policies in August 2025. Broker Jaggi of Jaggi Petry Insurance called it unprecedented in his 49-year career. Over 80 clients received notices without warning or ties to policy anniversaries.
This uniform hike blindsided retirees who rely on steady supplemental coverage to fill Original Medicare gaps. Brokers struggled to find comparable switches amid rising carrier-wide rates. Fixed-income seniors absorbed thousands in unexpected annual costs.

Amanda Brewton of Medicare Answers Now confirmed that double-digit hikes are becoming routine. Chalen Jackson of Integrity noted that increases under 10% are now rare, while those over 20% are common.
Patricia Mack in Alaska saw Premera Blue Cross increase premiums by 12% for a 65-year-old woman, from $172 to $192 monthly. Ohio shifted from 3-5% to 10-15% annually. These trends signal systemic pressures outpacing past norms, in which single-digit rises dominated.
Drivers Behind Widespread Rate Escalations
Higher medical utilization post-2020 fuels Medigap hikes. Aging Baby Boomers and shifts from Medicare Advantage back to traditional Medicare swell claims. Labor costs and Medicare adjustments, like Part B deductibles, are rising by $17, compounded by pressures.
Insurers file actuarial justifications with state commissioners who prioritize solvency. Premera blamed Medicare changes and spikes in usage.
Average Plan G premium hit $164 per month in 2023 and is now climbing double-digits across Aetna, Blue Cross Blue Shield, Cigna, Humana, Mutual of Omaha, and UnitedHealthcare.
Early 2026 Q1 filings confirm 12-26% Plan G increases. Attained-age pricing models escalate costs with age, hitting fixed Social Security budgets hardest. Community-rated and issue-age plans offer less long-term volatility, per an analysis by Medicare.org.
Historical data shows Mutual of Omaha starting competitively but rising higher over time; Humana’s low initial rates accelerate later. These patterns erode retiree protections for 43% of traditional Medicare users.
Stakeholders Grapple with Power Imbalances
Insurers wield pricing power through state-approved filings. Brokers like Jaggi push client switches but face slim options. State commissioners approve hikes favoring carrier stability over consumers.
Experts, including Jae Oh and KFF, highlight enrollment at 14.6 million by 2025. Sales incentives such as bonuses may steer seniors toward unsuitable plans, a critique that aligns with scrutiny of profit motives over retiree welfare. Retirees demand affordability without sacrificing coverage.
13% of traditional Medicare users lack supplemental coverage, leaving them at risk of unlimited out-of-pocket costs. Couples now pay $3,500-plus annually for Medigap and Part D; short-term shocks force hasty changes; long-term attained-age hikes devour budgets.
Economic strain cuts disposable income, limits access to care, and pressures Medicare reforms.
Viable Strategies Amid Limited Alternatives
Brokers recommend switching carriers during open enrollment and downgrading to high-deductible Plan G or F with a $3,000 deductible for lower premiums. Medicare Advantage caps costs but imposes networks and prior authorizations.
Health underwriting blocks switches for pre-existing conditions outside guaranteed issue periods. Compare rate histories and service records over coverage alone. KFF data show premiums averaging $217 per month in 2023, with wide variation by state and plan.
