MassHealth (Medicaid) & Children's Medical Security Plan

MassHealth and the Children’s Medical Security Plan provide health coverage pathways in Massachusetts. The application used depends on age, family circumstances and long-term care needs.

Who can apply

['Massachusetts residents seeking health or dental coverage. Eligibility varies by coverage category, income and other circumstances.', 'The health and dental coverage application serves most people under 65; seniors and people needing long-term care should check the separate application guidance.']

What help is available

Coverage determined by MassHealth’s eligibility notice. Read the coverage type and services listed before choosing a provider or assuming a bill is covered.

Documents to prepare

Prepare income and employer information, existing insurance, tax information if filed and identity or immigration records for applicants. Tell the assistance worker about missing documents rather than guessing.

How to get started

  1. Open the state application page and confirm which form fits your household.
  2. Use the available application route, or call MassHealth at 800-841-2900 for help and the correct form.
  3. For the health and dental paper application, use the state’s Health Insurance Processing Center mailing instructions.
  4. Ask about the separate senior or long-term care application when relevant.

After applying

Respond to requests for information and read the written eligibility notice. Some approved coverage types require health plan enrollment afterwards; follow the notice’s instructions and verify provider participation.
