Maintaining Your Enrollment

The 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, call MassHealth Customer Service at 1-800-841-2900.
