Abandonment question

I was the DON of a very small home health agency. I discovered the agency was performing unethical acts, eg, taking payment months later for a pt they attempted to say was deleted and not admitted with full episode visits attached. I gave a two week notice which they would not accept but I did not rescind. I had a health issue which required me to be absent from work, and it was in that time that my husband and I decided that it would not be a good idea for me to return. This was three days before my final day. I went into the system to reassign my patients to one of the other two nurses who worked for the agency and discovered that the patient visits had not been completed during my absence. So when I decided to leave and had transferred the patients to the next day, I was told by the office manager that neither of the other two nurses were available the next day. So I agreed to see the patients and gave my expected reimbursement issue to her. As I was a salaried employee, I told her I wanted to be paid 16 hours; 8 hours for the day before, as I had spent a good deal of time the day before in preparation and attempting to make visit adjustments to accommodate the visits, telephone calls to patients, etc., and 8 hours for the visits the next day. I told them I would not charge mileage, even though the mileage would have been extensive roughly 100 from my home, to the patients, then to the office to sign off. The office mgr said she could not make that decision. I told her that was what I needed and to get me an answer by the end of the day. A couple of hours later my reimbursement was declined. And I was then cut out of the system. I had already made visit arrangements but agency would rather compromise patient care then pay me to see the patients. Can I be charged with nursing abandonment?
