The Missouri Medigap Anniversary Rule: A Cass County Senior's Secret Weapon
A Rule Most People Have Never Heard Of
Over 311,000 Missouri residents currently hold a Medicare Supplement policy, and a sizable number of them have no idea their state offers something almost no other state does: an annual chance to switch Medigap carriers, for the exact same plan letter, with zero health questions asked.

How the Rule Actually Works
Missouri policyholders get a guaranteed-issue window 30 days before and 30 days after their policy’s anniversary date each year, allowing a switch to the same plan letter with a different insurance company, without medical underwriting. Since every Plan G is identical no matter who sells it, this means you can shop strictly on price, with zero health risk, once a year, every year.
Why Cass County Residents Specifically Benefit
Cass County, including Belton, Raymore, and Harrisonville, sits squarely in Missouri, meaning every Medigap holder here has access to this rule. Cross the state line into Kansas, and this protection disappears entirely, Kansas has no equivalent rule.

What This Doesn’t Mean
This isn’t a chance to switch plan letters, only carriers within the same letter. If you want to move from Plan N to Plan G, this specific rule doesn’t apply, that requires a different guaranteed-issue trigger or medical underwriting.
The Bottom Line
If you’ve held the same Medigap plan for years and never compared current rates, this rule exists specifically so you don’t have to keep overpaying. Most people simply don’t know to ask.
