<prompt> Human: Hi all, on mobile so theres that.I have Power of Attorney for my grandma and she has spent the last 2 days in the hospital. I came home and received the first bill of its kind to the grand tune of 123k! She receives 750 a month of Social Security and 3400 a month of disability pension, every penny goes to her care. Years ago I contacted a CPA and was advised that her income was tax free so filing taxes were not required. She has been estranged from her husband for over 10 years, though still married, and this is the only exposure I can think of that would create such a bill.I will be sending thw IRS the POA paperwork to get further insight, but this will take up to a week to process. Im trying to figure out what my options are and really, how bad could this be? Any feedbackadvice is appreciated. Edit: grandma has been in the hospital, not me. Assistant: Are you sure it is legit and not a scam?Human: Its the real deal. A letter with the correct phone number, even down to the 45 minute hold time!  <response>: This is what scammers do wrong. They answer instantly.
