Missouri Anniversary Date Medicare Rule

The Missouri Anniversary Date Medicare Rule is designed to grant beneficiaries the opportunity to modify their Medigap plans on the anniversary date of their plan each year. This rule aims to provide individuals with the flexibility to adjust their healthcare coverage according to their evolving needs without being constrained by specific enrollment periods.

Key Features:

  • Anniversary Date Flexibility: Individuals who terminate a Medicare supplement policy within  30 days of the annual policy anniversary date may obtain the same plan with no health questions asked for a period of 63 days after the termination of their existing policy, from any issuer that offers that plan.
  • No Medical Underwriting: An essential aspect of this rule is that individuals can change plans without undergoing medical underwriting. This means beneficiaries can make adjustments to their coverage without concerns about pre-existing conditions affecting premiums or coverage eligibility.
  • Same or Lesser Benefit Level: While beneficiaries can switch plans, they are required to choose a plan with an equal or lesser benefit level than their current plan. This ensures that individuals maintain a level of coverage consistent with their healthcare needs.This would include Medicare supplement and SELECT plans. For policies with an effective date of June 10, 2010 or after, individuals with existing Plans E, H, I and J can convert to one of the following Plans: A, B, C, F, K or L.
  • Coverage Continuity: Beneficiaries will not experience a lapse in coverage during the transition period. The new Medigap plan becomes effective on the anniversary date of the existing plan. 


Implications for Beneficiaries

The Missouri Anniversary Date Medicare Rule presents several advantages for beneficiaries:

  • Flexible Timing: Beneficiaries can reassess their healthcare needs and adjust their Medigap plans on their plan’s anniversary date, providing a personalized timeline for plan modifications.
  • Cost Savings: With the option to switch plans without medical underwriting, beneficiaries may find opportunities to save on premiums or secure better coverage based on their current health status.
  • Tailored Coverage: The rule allows individuals to tailor their coverage to their evolving healthcare requirements, ensuring they have the most appropriate plan for their circumstances.
  • No Penalties or Restrictions: Unlike some states where switching Medigap plans may be subject to penalties or limitations, the Missouri Anniversary Date Medicare Rule provides a relatively unrestricted environment for beneficiaries to make changes.



The Missouri Anniversary Date Medicare Rule is a valuable resource for Medicare beneficiaries in the state, offering personalized flexibility in choosing and adjusting their Medigap plans. By allowing individuals to reassess their coverage on the anniversary date of their plan each year without facing the usual underwriting restrictions, Missouri residents can ensure that their healthcare coverage aligns precisely with their evolving needs. Beneficiaries should be aware of this rule and take advantage of the opportunity it presents on the anniversary date of their Medigap plan.
