Medigap letters: compare benefits before company names
A row of letters can make a simple question feel complicated. Start with the coverage you want to compare, then look at the companies offering it.
In most states, Medigap uses standardized plan letters. The same letter has the same basic benefits across insurers. Prices can differ. Massachusetts, Minnesota, and Wisconsin use different standardization systems.
Do not confuse a Medicare part with a Medigap plan
Medigap helps with eligible Original Medicare cost sharing. A Medigap Plan A is not Medicare Part A. Write the full name on your comparison sheet so a conversation about a supplement does not get mixed up with the underlying Medicare benefit.
Use the official benefit chart
The standardized letters offered in most states are A, B, C, D, F, G, K, L, M, and N. Start with Medicare’s official comparison chart linked below. Read the footnotes along with the benefit rows. A partial benefit or a special condition can be easy to miss when looking only at the letter.
Notice the important variations
Eligibility for C and F depends on when you first became eligible for Medicare. Some states offer high deductible versions of F and G. K and L have their own annual out of pocket limits. N includes certain office and emergency room copayments. These are reasons to compare carefully, not a ranking of which plan is best.
Compare quotes on the same basis
Use the same plan letter, state, effective date, and applicant information when requesting quotes. Ask whether the quoted premium depends on a discount and how pricing can change. Keep the quote and benefit explanation together. A low starting price is only one part of the conversation.
Check buying rights before making a change
Your ability to buy a policy can depend on timing, state protections, and medical underwriting. Do not cancel existing coverage before confirming acceptance and the new effective date. Use the enrollment rights guide below to prepare questions about your own situation.
