Medicare Supplement Plans in Missouri

For many Medicare beneficiaries, Medicare Supplement plans in Missouri provide peace of mind when it comes to health care costs. Because your Medicare coverage doesn’t pay 100% of your medical expenses, you will have to pay some out-of-pocket costs. A Medicare Supplement plan can reduce the amount you have to pay and protect you against unexpected or large health care bills.

You can only buy called Medigap insurance, if you receive your Medicare benefits through Original Medicare:

  • Medicare Part A (hospital)
  • Medicare Part B (doctor/outpatient)

Eligibility for a plan in Missouri begins when:

  • You turn 65 and
  • You’re enrolled in Part B

All Medigap plans in MO offer identical basic benefits. Some plan options include additional coverage. No Medicare Supplement insurance plan will cover the following:

  • Dental, hearing, or vision
  • Long-term care
  • Prescription medication (Part D)

When Can I Enroll in a Medicare Supplement Plan in Missouri?

Medicare Supplement plans in Missouri have a Medigap Open Enrollment Period. Your OEP is a six-month period that starts when your Part B takes effect. Enrolling during your OEP is the best time because you have guaranteed issue rights:

  • Guaranteed coverage, including for pre-existing conditions
  • No waiting periods
  • Insurer cannot charge more based on health conditions

As long as you renew your current plan each year, insurers cannot refuse you coverage.

Missouri Anniversary Rule

In many states, if beneficiaries change companies or plans after their OEP, insurers can refuse coverage or charge higher premiums. In Missouri, the Missouri Medicare Supplement Anniversary Guaranteed Issue Rule allows you to change companies or plans once a year. You have a 30-day window before and after the effective date of your insurance policy (60 days total). Here’s how it works:

  • Change carriers, keep the same plan: new insurers cannot refuse coverage or impose a waiting period for pre-existing conditions
  • Switch plans, less coverage: might or might not be subject to underwriting
  • Change plans, greater coverage: underwriting likely, insurers can deny coverage or impose a waiting period for pre-existing health conditions

Medigap under age 65 in Missouri

Any Missourian under age 65 eligible for Social Security can join a Medicare Supplement insurance plan in Missouri with guaranteed issue rights.

  • Must be enrolled in Original Medicare
  • Premiums might be different from Missourians who age into Medicare.
  • When they turn 65, they have a second OEP with the same rights as others newly eligible for Medigap insurance.

You have guaranteed rights in a few other situations. Our licensed insurance agents can provide guidance if you have questions about your eligibility for Medigap insurance
