Does a patient in a SNF have to stay because of teeth needing extraction and not having a home to go to?

Patient has been in a SNF for eight months cannot get his SSI back because no address to give to the SNF for discharge. He is more then capable of caring for himself besides getting his teeth out. He is 55 yrs old. Went in for a minor infection after month he recovered now eight months later he is tested non covid-19. In the SNF with over 59 positive covid-19. And 11 staff positive. SNF will not discharge him without an address to go to. Please help with your support. Thank You God Bless all Covid-19 patients and caregivers.
