Maintaining Enrollment

Children's Medical Security Plan (CMSP) is a MassHealth program that is managed by MassHealth and administered by UniCare.

Every year, you will get a MassHealth Eligibility Review Form (ERV) in the mail. It is important that you fill out and return the eligibility review form to a MassHealth office right away. MassHealth needs this information to make sure that your child or children are still eligible for CMSP benefits. Your child or children might even be eligible for other MassHealth coverage, which may give them more health services.

If you have any questions about filling out the ERV form, you may call MassHealth Customer Service at 1-800-841-2900.

This is what you need to know about maintaining your child's or children's CMSP enrollment active.

  • If you do not complete and return the form to MassHealth within the time frame allowed by MassHealth, your child or children will lose their CMSP benefit.

  • Send all MassHealth-requested verifications to the MassHealth office within the time frame allowed. Examples of verifications requested by the MassHealth office include, but are not limited to:


    • verification of gross earned income; and
    • verification of gross unearned income.


  • Report to MassHealth within the time frame allowed any change in household circumstance that may affect the eligibility of your CMSP benefits or premiums. Examples of changes include, but are not limited to:


    • income;
    • family size
    • availability of other health insurance;
    • third-party liability (other health insurance); and
    • address.


  • If you are in a premium-billing category, the timely payment of the premium to MassHealth is required in order to maintain active CMSP coverage.
