Is it legal for elder care services to lie in family court that my father has no power of attorney, health care proxy or health insurance?

I was caring for my Dad in the process of finding assisted living and I was detained by police for a warrant. Because my husband was alone with my Dad and would not let my husband change him, my hubby had brought him to the ER! I was held up for two days and when I went to go get my father I was told I was not allowed to see him. Elder care with no court order told hospital no family or friends are to see him? Furthermore, out of blue I was now being investigated for exploitation, during which the elder care social worker went to court after leaving me a message the day before and didn’t mention court next day. She only said she wants to let me know about some upcoming court dates and that my father was brought up in the ER with several saturated diapers, sores, and eating at a very fast pace. My father had no sores and he had on extra diapers because they all leaked and that was how we kept him clean and dry and he began eating fast as the disease progressed! He was far from underweight. I cooked dinner every night and believe me he loved to eat. If he had sores or any medical issues, the hospital would report that and it wasn’t in the reports. Also he remained in the ER because they had no reason medically to admit him until he was left in a bed at the ER for several days develop a UTI. He never was taken out of bed for a walk or fresh air, no visits from me whom he still recognized, and he remained in a bed until he died a year later in a 1 star Nursing hospital!
