What you are describing is neither malpractice nor negligence.
You are claiming you were denied your legal rights as a psychiatric inpatient in NYS. Mainly by being denied information about your status as a patient (voluntary/involuntary), what you were being treated for, what your treatment plan was, the purpose of the medication you were given, etc.
Quite honestly, I have difficulty believing the accuracy of your account.
For instance, you say there was a statement posted on the wall explaining your legal rights as a psychiatric patient, those statements include a phone number to call the Mental Hygiene Legal Services about any issues related to your hospitalization, and there was a pay phone on the unit, and you had quarters to use the phone. Why didn't you call them? You were not prevented from doing that. The MHLS would have advised you of why you were admitted, your status as a patient, your right to refuse medication, your right to request a court hearing, how to request your release, etc.
You definitely did have legal rights while hospitalized--either you chose not to take advantage of them, or your psychiatric condition at the time may have interfered with your ability to do so. Those statements are posted on the walls of inpatient psych units for a reason--they want patients to use the information, they want patients to call the MHLS if they have questions, or problems, or require legal assistance.
Were you court-ordered to go for outpatient treatment after your discharge? How did anyone "coerce" you to do this? Did you ask that psychiatrist what you were being treated for?
Have you asked the relative who took you to the ER why he/she did so? How were you acting that made someone think you needed to be seen in an ER? Do you have any prior history of psych hospitalization or psych treatment? Any history of alcohol or drug abuse?
Truthfully, I think you likely were suffering from some psychiatric condition that did require inpatient treatment but you seem to have no insight or understanding of what that might be. It's better that you do find out what you were being treated for since many conditions can be recurrent.
The easiest thing to do is to either call or pay a visit to the psychiatrist you saw after your discharge--who apparently treated you during your hospital stay as well--and ask him why you were hospitalized, what you were treated for, what your symptoms were, and what your discharge diagnosis was. Just accept whatever he says, without arguing about it or questioning it--just get the information. And then just think about it.
You might also want to discuss what the psychiatrist tells you with your family--again without arguing about it. I think you need to be open to the possibility that your hospitalization was necessary and justified, and that your memory and perception of events might not be accurate.
If, after getting information from the psychiatrist, and discussing it with your family, you still really think the hospital violated the Mental Hygiene laws, and your rights as a patient, during your hospital stay--which I don't think was likely--find the appropriate MHLS office that covers the county for the hospital you were in, from the list on this page, and contact them regarding your complaints.
The situation you describe is not
malpractice. It is about issues related to the legal rights of psychiatric inpatients.
The hospital will not send you your medical records--don't bother to ask.
Do not try to involve the insurance carrier in any of this--it is not their concern.
You may have to pay that $5000--the services were delivered, there is no issue of fraud--unless you can work out a lower amount with the billing department of the hospital. I wouldn't count on that, but it might be worth a try.
