What Plan G covers
Plan G covers everything Original Medicare doesn't, EXCEPT the Part B deductible ($240/year in 2026). Plan F (which covered Part B deductible) was discontinued for new enrollees in 2020.
Plan G is the most popular for new enrollees post-2020 because it covers the same expensive gaps (Part A deductible, Part B coinsurance, etc.) at lower premium than Plan F historical cost.
Plan G alternatives: Plan N (lower premium, $20 copay per office visit + $50 ER copay) for healthy seniors who don't visit doctors often. Plan G is the safe default.
Premium by carrier and state
65-year-old Plan G monthly premium by state and carrier: Florida averages $180-220 (highest), Texas $130-170, California $150-200. Florida's high premiums are due to retirement demographics and hurricane risk.
Cheapest carrier: Aetna $140-190/mo across states. Most expensive: Blue Cross Blue Shield $160-220/mo (varies by state BCBS).
Rate-increase history (5 years): UnitedHealthcare AARP averaged 4-6% annual increases, Mutual of Omaha 5-7%, Aetna 5-8%, Humana 4-7%, BCBS varies widely by state. Rate stability matters more than initial premium for long-term holders.
Bundled benefits and customer service
Bundled extras: Aetna includes SilverSneakers gym membership (worth $25-50/mo equivalent), free hearing aid discounts, vision discounts. UnitedHealthcare AARP includes Renew Active (gym + brain games). Mutual of Omaha includes basic discount programs. Humana and BCBS more limited extras.
Customer service ratings (BBB + AM Best): UnitedHealthcare A+ AM Best, Mutual of Omaha A+ AM Best, Aetna A AM Best, Humana A AM Best, BCBS varies by state.
Pre-existing condition treatment: Medicare Supplement is guaranteed issue ONLY during Open Enrollment (first 6 months after Part B starts). Outside that window, carriers can underwrite — and decline.
