Centuries Mutual
Medicare Supplement
Medicare Supplement (Medigap) options that help cover deductibles, coinsurance, and copayments left by Original Medicare — with clear timing guidance, standardized plan-letter comparisons, and a membership sign-up flow that keeps every policy document in one place.
Enrollment flow
From membership to Medigap policy
A four-step path: create your account, review lettered plan tradeoffs, confirm enrollment timing, and complete application paperwork with documents on file.
- 01
Create membership
Open a Centuries Mutual account so Medigap applications and policy files attach to your identity.
- 02
Compare plan letters
Review standardized letter designs side by side — premiums versus the gaps you want filled.
- 03
Confirm timing
Open enrollment and guaranteed-issue windows are called out before you apply so underwriting surprises stay rare.
- 04
Apply & archive
Complete the application and keep cards, EOBs, and correspondence in your Documents library.
Insurance pathway
Help with what Original Medicare leaves behind
Original Medicare pays a share; you may still owe deductibles, coinsurance, and copayments. Medicare Supplement plans are standardized lettered designs that help make those balances more predictable.

A Centuries Mutual pathway to standardized Medigap coverage that helps fill Original Medicare gaps. Not Medicare Advantage, not a guarantee of issuance outside applicable enrollment rules, and not a substitute for Official Medicare publications or plan documents.
