I got this text message from my sister this morning:

Jessica 1 from Social Security called me this morning to verify where Mom was. I gave her the phone number for Woodland Terrace. She is going to contact them to verify Mom's status and inability to sign her name and send them some forms.
I spoke briefly with Shelly. She has not looked at the Medicaid site 2 but will talk to Sylvia about it. She said she wouldn't have any answers until then.

1 I don’t really know which Jessica this is. I think I’ve interacted with at least three different women named Jessica involved with Social Security and / or Medicaid in the last nine months.
2 I can’t imagine how Shelly is going to be able to view anything on the Medicaid website (unless my sister has simply given her mom’s authentication information).
