There are many Medigap policies offered by many different insurers, so this is hard to answer. Plan F is the most robust coverage, currently, and it will be the most expensive, with premiums that can go up to $10,000 a year.
There isn’t a concrete answer.
Your costs will depend on how old you are, your health, and which of the 12 plans you choose. Medigap policies come in flavors such as Part F, Part K, and Part L.
Generally speaking, Medigap policies are not cheap, since they cover all (or most) of the out-of-pocket costs for part A and part B, for a population with a very high claims rate. Part F policies can range from about $3,000 to $10,000 a year, depending on age and other factors, but they are the most expensive due to the full coverage they provide.
