This document discusses Medicare supplement (Medigap) insurance plans. It explains that although all Medigap plans offer the same basic benefits, premiums can vary between plans based on how the insurance company determines pricing. Premiums are typically based on either issue-age (when enrolled), attained-age (current age each year), or community rating (same price regardless of age). The document encourages working with an independent agent to compare options from the dozens of insurers offering Medigap, in order to find the best priced plan. It also clarifies that consumers can change plans at any time without restrictions.
