5 Reasons Retirees Should Choose Medigap Plan G Over Medicare Advantage in 2026

Medicare Advantage premiums are lower than Medigap Plan G premiums, but the total cost depends on how much care is needed. Plan G charges a known monthly premium, and after the Part B deductible, covered medical costs are essentially zero. Medicare Advantage charges little up front and instead uses copays and coinsurance until an annual out-of-pocket maximum is reached. In healthy years, the lower MA premium can produce large savings. In high-cost years such as cancer treatment or major surgery, the MA out-of-pocket maximum can make Plan G cheaper. Plan G also provides access to a much larger share of physicians and avoids narrow, county-based networks that can disadvantage travelers and people living in multiple states.

"Plan G charges a known monthly premium so that, after the $283 annual Part B deductible in 2026, your covered medical costs are essentially zero. Medicare Advantage charges almost nothing up front and bills you through copays and coinsurance up to an annual out-of-pocket maximum. A Plan G holder paying around $215 a month spends roughly $2,580 a year on premium, plus the Part B deductible. An MA enrollee paying $14 a month spends about $168 in premiums but is exposed to an in-network out-of-pocket maximum as high as $9,350, or up to $14,000 when out-of-network care is included."

"You are healthy now, the MA brochure shows a $0 or near-$0 premium with dental and a gym membership, and Plan G looks expensive by comparison. The catch is that the choice you make at 65 is much easier to reverse in one direction than the other. The premium gap is real. The total cost picture is not what it looks like."

"Plan G turns medical costs into a fixed line item. For retirees on a 4% withdrawal rate, knowing your healthcare ceiling matters more than shaving $200 a month off premiums. National provider access. Original Medicare with Plan G is accepted by roughly 98% of physicians. MA plans run narrow networks tied to a county or metro. Snowbirds, frequent travelers, and anyone with adult children scattered across states benefit from carrying coverage that works everywhere."

"In a healthy year, MA wins by thousands. In a cancer year or a hip replacement year, Plan G wins by more. A healthy-year comparison can hide the risk of catastrophic exposure because MA costs are capped only at the annual out-of-pocket maximum, while Plan G is designed to make covered medical costs essentially zero after the deductible."
