Allstate no longer sells new Medicare Supplement plans: in May 2025 its Allstate Health Solutions unit (formerly National General) switched to paper-only applications and began withdrawing from the market state by state. Existing policies, issued mainly by National Health Insurance Company (rated A, Excellent, by AM Best), stay in force as long as you pay the premium.

Many guides still describe Allstate as a fresh Medicare Supplement option with a household discount and an A+ rating. That picture is out of date. In 2025 Allstate sold two of its health businesses, kept a smaller individual health unit, and told agents it was leaving the Medicare Supplement market.
If you already own an Allstate or National General policy, your coverage has not changed. This page explains what did change, which company actually backs your policy, what drives your Plan G premium from here, and how to compare it with an open carrier.
