About Medigap Atlas

A small, independent, ad-supported site that explains Medicare with sources.

Medigap Atlas is written and maintained by James J. I am not a licensed insurance agent, broker, attorney or Medicare counselor. I started this site because most Medicare websites are run by companies that earn commissions when you enroll in something, and I wanted a place that shows the rules and the sources without a sales pitch.

We do not sell plans, collect leads, take commissions or recommend an insurer. The site is supported by ads, and ads on a Medicare page are not endorsements. Nothing here is insurance, legal or tax advice. For personalized help, call 1-800-MEDICARE or your free State Health Insurance Assistance Program (SHIP).

General information only. Medigap Atlas does not sell, recommend or enroll anyone in any plan, and is not affiliated with Medicare, CMS or any insurer. Rules and dates change and vary by state. Confirm your options with 1-800-MEDICARE (1-800-633-4227) or your State Health Insurance Assistance Program (SHIP) before you change coverage.
