Question regarding medical mistreatment

I am asking this question for a friend. She recently was checked into an urgent care and had to have surgery on her knee and foot for a Staphylococcus infections. The prematurely discharged her under the guise of another rehab facility accepting her to continue the healing process. They did not disclsoe the full acceptance information such as the co-pay of $3K or that it was required up front. When she found this out, she came back to the original facility in order to continue the monitoring and treatment but was told they already had filled her bed and that they didn't have room for her. When they initially released her, they also left the pik line in her arm which she then ended up removing herself. Can anything be done about this? The pik line should not have been left in and the overall treatment was attrocious. Is there any grounds for a civil or malpractice suit?
