You need to be on your own health plan now. The 26 age thing does not apply to Masshealth plans. Only to employer/private health coverage. Once you marry you are no longer eligible on your fathers Masshealth plan, and need to find your own health insurance. If you do not have health coverage through your employer. And your husband does not have it available through his. You have to apply for it yourselves via Masshealth. Either individually, or as a married couple.
