MassHealth members can have both MassHealth and private health insurance at the same time. If you have both types of insurance, the private health insurance is considered a liable third party or “TPL”. This means the private health insurance is billed as the primary insurer and MassHealth is the secondary coverage. Private health insurance could be from your job, a family member, or a parent with or without custody. In some instances, MassHealth may require you to enroll into health insurance offered through work.
If you are a MassHealth member and you have private health insurance
- You will not lose your MassHealth as long as you are still eligible for MassHealth;
- Your private insurance will be the primary insurer and pay first for your health care;
- MassHealth will pay for MassHealth-covered services if your private health insurance doesn’t, including out-of-pocket costs like copays or deductibles;
- You will never have to pay more than you did when you or your dependents were on MassHealth only;
- If you were receiving your MassHealth through a MassHealth managed care organization (MCO) plan (e.g. BMC Health Net or Tufts Health Together), an accountable care organization (ACO) plan (e.g. Fallon 365 or Partners HealthCare Choice), or through the Primary Care Clinician (PCC) Plan you will be disenrolled from the MassHealth MCO, ACO, or PCC Plan once you become enrolled in your private health insurance. An MCO, ACO, PCC Plan disenrollment notice will be mailed to your address that MassHealth has on record when this happens. You will still have MassHealth benefits, however how you receive them will change.
If you are a MassHealth member and may have access to private health insurance
You may be required to:
- Supply information about the private insurance plan to see if it would be cost effective for MassHealth to require you to enroll;
- Enroll in insurance through your job if MassHealth determines it is cost-effective. MassHealth will reimburse you for any costs in addition to those you had with MassHealth only;
- Maintain any private health insurance that is available to you at no cost (including Medicare); and
- Unless you are pregnant or under age 21, you could lose your MassHealth benefits if you do not enroll in private health insurance when you are required to do so by MassHealth.
