Please read & make your coverage choices carefully & informed!
Every Medicare choice is priced for two kinds of years. In a healthy year, the premium is most of the bill. In a bad one, with a hospital stay, surgery or months of treatment, what matters is the most the plan can make you pay.
Original Medicare on its own has no ceiling. Medicare.gov says there is no yearly limit on what you pay out of pocket unless you have supplemental coverage or other insurance.
Standard Plan G closes most of that gap. It covers everything Plan F does except the Part B deductible, which is $283 in 2026, and it also pays Part B excess charges. So for Medicare-covered care, a Plan G holder's own share of a bad year in 2026 tops out at that $283, with any doctor in the country who takes Medicare. What Plan G charges instead is a premium, set by each insurer and paid every month, healthy year or not. In some states a high-deductible version pays nothing until $2,950 of costs in 2026.
Medicare Advantage plans each set their own yearly limit, inside ranges CMS publishes. For 2026, a plan's in-network limit falls in one of three bands: up to $4,200, $4,201 to $6,750, or $6,751 to $9,250. A PPO that also covers care outside its network has a second, combined limit, which for plans in the top band can reach $13,900. An HMO generally covers only care from its network, apart from emergency care, out-of-area urgent care and temporary dialysis away from home.
In a healthy year the math often leans the other way. Some Advantage plans have a $0 premium, and most include drug coverage, so there is no separate Part D premium. Both paths still pay the $202.90 monthly Part B premium.
What decides it is a year of Plan G premiums held against the gap in a bad year. Against a plan at the top of the range, that gap is up to $8,967 in network, the $9,250 limit minus Plan G's $283. Against a plan with a $4,200 limit, it is $3,917. That is why the plan's own limit matters more than CMS's ceiling.
The ceilings move each year. For 2027, CMS has set the top in-network limit at $9,850 and the top combined limit at $14,800. And the choice can be hard to undo. Outside the Medigap Open Enrollment Period and a few protected situations, an insurer can turn down a Medigap application based on health.
