Do I need to notify health insurance co that my mom passed?

Probably wouldn't hurt.

With my grandmother, it resolved itself and my mom didn't have to do anything.

Update: I called her health insurance provider and they said they would have to get the info from SSA or DHHS. (She was on Medicaid.)

If she had a Medicare Advantage u probably need to. Medicare is notified when Social Security is by the funeral home. My Moms supplimental was thru Dads employer so I hadvto call benefits to stop that and her pension. Medicaid was notified by the Nursing home.

I only had to inform Social Security. Insurance they will know by the SS number.

My MIL just passed away in a LTC facility this past Sunday of a holiday week, so there were no admins to give us guidance, but the Chaplain thankfully was there and very helpful, then the hospice lead came. When the rep from the crematory came to receive her body I got info from her about next steps. Then the next day the Cremation Society (where we purchased the cremation policy) made an appointment to have a phone briefing with us the next day. The Cremation Society rep informed us that Medicaid, Medicare and SS would be notified by them through the process of them filing the death certificate. So, assuming your Mom was over 65 and on Medicare, you shouldn't have to inform them or SS of her passing. This is assuming this process isn't state-specific. I'm sorry for your loss.

When my dad died, I notified all of his insurance companies, and SSA. It was a surprisingly easy process.
