Missouri Medicare Supplement Plans: What You Need to Know
Missouri has over 1.1 million Medicare beneficiaries across major metros like Kansas City, St. Louis, Springfield, Columbia, and Independence, as well as rural communities throughout the state. What makes Missouri unique is its birthday rule, which gives you an annual opportunity to switch Medigap plans for better rates without medical underwriting.
Like other states, Medigap plans in Missouri are standardized by letter (A, B, C, D, F, G, K, L, M, N). This means a Plan G from one company covers exactly the same benefits as a Plan G from another company. The only differences are the premium you pay and the company's customer service.
Missouri's Birthday Rule: Your Annual Rate Shopping Opportunity
Missouri law gives you a 30-day window starting on your birthday each year to switch Medigap plans without medical underwriting. Here's what you need to know:
- The window: 30 days starting on your birthday (not before)
- What you CAN do: Switch to a plan with equal or lesser coverage
- What you CANNOT do: Switch to a plan with more coverage without underwriting
- Example: You can switch from Plan G to Plan N, or Plan G to another company's Plan G, but NOT from Plan N to Plan G
- Why this matters: You can shop for better rates every single year!
Missouri Medigap Open Enrollment Period
If you're new to Medicare, your Medigap Open Enrollment Period begins on the first day of the month you turn 65 and are enrolled in Medicare Part B. This 6-month window is critical because:
- Insurance companies cannot deny you coverage for any reason
- They cannot charge you more due to health conditions
- You have guaranteed issue rights to any Medigap plan sold in Missouri
After this initial 6-month period, you can still use Missouri's birthday rule to switch plans annually, but only to plans with equal or lesser coverage.
Most Popular Medigap Plans in Missouri
While 10 standardized Medigap plans are available in Missouri, the most popular choices are:
| Plan | Coverage Level | Best For | MO Monthly Premium* |
|---|---|---|---|
| Plan G | Comprehensive | Most new enrollees (best value) | $120 - $200 |
| Plan N | High with copays | Those wanting lower premiums | $90 - $150 |
| Plan F | Most comprehensive | Those eligible before 2020 | $150 - $250 |

Plan G vs Plan N in Missouri
For most Missouri residents new to Medicare, the choice comes down to Plan G or Plan N:
- Plan G covers everything except the Part B deductible ($240 in 2024). No copays, no surprises. Ideal if you want predictable costs and visit doctors frequently.
- Plan N has lower premiums but requires up to $20 copays for office visits and up to $50 for ER visits (waived if admitted). Good choice if you're healthy and want to save on monthly costs.
Thanks to Missouri's birthday rule, you can switch between these plans annually if your needs change, as long as you're moving to equal or lesser coverage.
Missouri-Specific Medicare Considerations
Using the Birthday Rule Strategically
Missouri's birthday rule is a powerful tool for rate shopping. Here's how to use it strategically:
- Review rates annually: About 60 days before your birthday, compare rates from different carriers for your current plan
- Consider plan changes: If you're healthy and want to save money, you could move from Plan G to Plan N during your birthday window
- Avoid the trap: If you switch to Plan N, you cannot switch back to Plan G without medical underwriting, so think carefully
- Get help: A fee-only Medicare advisor can help you evaluate whether switching makes financial sense
Urban vs Rural Coverage in Missouri
Missouri's mix of major metropolitan areas (Kansas City and St. Louis) and extensive rural areas affects your Medicare options. If you live in or frequently travel to rural Missouri, Medigap offers a significant advantage: any doctor or hospital that accepts Medicare will accept your Medigap plan. This is critical in areas where specialist care may require traveling to larger cities.
CLAIM: Missouri's Free Medicare Counseling
Missouri offers a free counseling program called CLAIM (Community Leaders Assisting the Insured of Missouri). CLAIM counselors can provide general Medicare information and help you understand your options. However, they cannot recommend specific plans or companies. That's where a fee-only Medicare advisor adds value: we can make specific recommendations based on your individual situation.
Cross-Border Considerations
If you live near Missouri's borders with Kansas, Illinois, Iowa, Arkansas, Oklahoma, Nebraska, Kentucky, or Tennessee, you may receive care across state lines. With Medigap, this is no problem. Your coverage works anywhere in the United States where Medicare is accepted. Medicare Advantage plans often have network restrictions that can be problematic if you regularly cross state lines for care.
Frequently Asked Questions: Missouri Medicare
You can switch Medigap plans in Missouri during three main times: (1) Your initial 6-month Medigap Open Enrollment Period when you first enroll in Part B, (2) During your 30-day birthday window each year (to equal or lesser coverage only), or (3) Anytime with medical underwriting (the company can deny you or charge more based on health).
Starting on your birthday each year, you have 30 days to switch to a Medigap plan with equal or lesser coverage without medical underwriting. This means you can switch from Plan G to Plan N, or from one company's Plan G to another company's Plan G, without answering health questions. However, you cannot use the birthday rule to upgrade to more coverage (like Plan N to Plan G) - that would require medical underwriting.
No. Missouri's birthday rule only allows you to switch to equal or lesser coverage. You cannot switch to a plan with more comprehensive benefits during this window. This is why it's important to choose comprehensive coverage (like Plan G) initially if you want maximum flexibility during your birthday windows.
CLAIM (Community Leaders Assisting the Insured of Missouri) is Missouri's free State Health Insurance Assistance Program (SHIP). CLAIM counselors can provide general Medicare information, explain your options, and help you understand the differences between plans. However, they cannot recommend specific insurance companies or plans. For personalized recommendations, consider working with a fee-only Medicare advisor.
