Medigap policies are standardized
Every Medigap policy must follow federal and state laws designed to protect you, and it must be clearly identified as "Medicare Supplement Insurance." Insurance companies can sell you only a "standardized" policy identified in most states by letters.
All policies offer the same basic benefits but some offer additional benefits, so you can choose which one meets your needs.
In Massachusetts, Minnesota, and Wisconsin, Medigap policies are standardized in a different way.
Each insurance company decides which Medigap policies it wants to sell, although state laws might affect which ones they offer.
Insurance companies that sell Medigap policies:
Don't have to offer every Medigap plan
Must offer Medigap Plan A if they offer any Medigap policy
Must also offer Plan C or Plan F if they offer any plan
* Plans F and G also offer a high-deductible plan in some states. With this option, you must pay for Medicare-covered costs (coinsurance, copayments, and deductibles) up to the deductible amount of $2,340 in 2020 ($2,370 in 2021) before your policy pays anything. (Plans C and F aren't available to people who were newly eligible for Medicare on or after January 1, 2020.)
** For Plans K and L, after you meet your out-of-pocket yearly limit and your yearly Part B deductible, the Medigap plan pays 100% of covered services for the rest of the calendar year.
*** Plan N pays 100% of the Part B coinsurance, except for a copayment of up to $20 for some office visits and up to a $50 copayment for emergency room visits that don't result in inpatient admission.
As of January 1, 2020, Medigap plans sold to new people with Medicare aren't allowed to cover the Part B deductible. Because of this, Plans C and F are not available to people new to Medicare starting on January 1, 2020. If you already have either of these 2 plans (or the high deductible version of Plan F) or are covered by one of these plans before January 1, 2020, you’ll be able to keep your plan. If you were eligible for Medicare before January 1, 2020, but not yet enrolled, you may be able to buy one of these plans.
