Coverage Information


No child should go without the medical or dental care he or she needs. The Children's Medical Security Plan is a program offered by MassHealth that provides the basic medical and dental coverage that kids need most. If you would like to know how to enroll in the Children's Medical Security Plan, please call MassHealth Customer Service at 1-800-841-2900.

CMSP is for children under the age of 19 who are Massachusetts residents at any income level, who do not qualify for any other MassHealth coverage type (except MassHealth Limited), and who do not have physician and hospital health-care coverage. The amounts you pay for coverage depend upon your total family size and income and may even be free.

Some children with CMSP are also eligible for MassHealth Limited, which covers emergency and inpatient services. For a detailed list of the services covered, please contact MassHealth Customer Service at 1 800 841-2900.

Some children may also be eligible for Health Safety Net services provided at acute-care hospitals and community health centers. For information on the Health Safety Net, you can call the HSN Helpline at 877-910-2100 or go to their Web site.
