health insurance coverage for Massachusetts residents age 18 and older.
Your 2023 Form 1099-HC will be mailed to you by your health insurance carrier by January 31st,

    had coverage with during the calendar year. For example, if you were initially covered under
    Blue Cross Blue Shield of MA and during open enrollment, you decided to change to Mass
    General Brigham Health Plan, you will receive a 1099-HC from BCBSMA for 1/1/23-6/30/23 and
    a 1099-HC from MGBHP for 7/1/23-12/31/23.
    Note: This proof of coverage is REQUIRED for your Massachusetts state income tax filing.
    If you did not receive your 1099-HC form or need to request another copy, you can access the
    document on demand by visiting the member portal for your respective health plan.
    Additionally, you can call the health plan directly to request a new form. Below is the portal link
