My mom was in rehab for alcohol abuse. She's been in there a few weeks. She had an upset stomach after lunch and threw up. They tried to make her go to a hospital but she didn't feel it was necessary just because she was nauseous so they booted her out of her rehab facility before she was done with her program. Can the facility legally do that?
Mm. Most people wouldn't go to hospital "just" because they felt nauseous after eating a meal, perhaps a meal that disagreed with them in some way.
But your mother was in rehab for alcohol abuse. Nausea in a person who's being treated for alcohol abuse could be an extremely important clinical sign - there's no "just" about it - and the rehab unit would have been negligent had they not insisted on its investigation.
So, they've not so much booted her out, as refused to take any further responsibility for a patient who will not allow them to act responsibly.
Vomiting could be symptomatic of an upset stomach or something very serious, in the context of detoxing from alcohol. The facility has every right to insist that your mom follow their rules and protocols.
If her medical chart shows that she left the facility AMA - against medical advice- the next time she tries to use her insurance & if it’s on the same IDC-10 codes as the AMA notation in her chart, insurance may not pay the claim.
