When my mom passed away this past summer, I think the funeral home or the nursing home notified SS. For some reason I thought that would end her insurance premiums as well, but as they were Medicare run through BCBS, it didn’t work that way, and I had to handle that myself. I noticed it when I got around to looking at the bank statements.
So they notify the government entity that is “giving”, but not the entities that are taking away. I guess I should have seen that coming.
One of the downfalls of the “automatic payment withdrawal” scheme is that you have to stop them and that is, at minimum, a PITA.
