After you enroll in a MO HealthNet Managed Care health plan, you will get a confirmation letter in the mail about your health plan and the date your services will begin. If a health plan was chosen for you, the letter will have the name of the MO HealthNet Managed Care health plan, along with the day you start with the health plan. You can start getting care the day your services begin. You may begin scheduling appointments before your services begin, but the appointments must take place after you start your health plan. Please contact your health plan if you have questions.
