Received a Medicare Renewal Form, But My Husband Never Enrolled—What Should We Do?

Hi, we received a Medicaid eligibility renewal form addressed to my husband, but he doesn’t remember enrolling and has never used the services. He doesn't have a life insurance only has accidental insurance through work.

We got married in July 2024, and the form asks for spouse info, he never updated his marital status since he wasn’t aware of this enrollment. We’re unsure if letting it lapse could cause penalties or if we should update the form and submit it.

Any advice on what we should do—fill it out, contact someone, or just ignore it—would be greatly appreciated!

Update : I'm sorry it's not medicare but medicaid assistance. We received this letter from District office division of public assistance department of health (State of Alaska).
