When you are approved for MO HealthNet Managed Care, you will be assigned a Managed Care health plan. You have the right to change this health plan if:

  • It has been less than 90 days since you were assigned a health plan
  • It is your annual open enrollment period and you do not want to stay with the same health plan
  • You have “just cause” and the state approves your request

If you would like to change health plans, you will need to fill out and submit a change request form for each family member’s health plan you would like to change.

You will get a confirmation letter in the mail about your new MO HealthNet Managed Care health plan and the date your coverage began. You will also get a welcome packet from the Managed Care health plan.
