My story is very similar to this Ashley Cervantes who was also taken to Holy Cross Hospital and billed for a search [0, 1], except in my case they got a warrant which was signed by the judge AFTER (MOST OF) THE SEARCH.
Like Ashley, nothing was found and I was billed afterwards. Ashley's case was even more shocking as she was forcibly and intimately penetrated by the doctor "in search of contraband" at the direction of DHS.
In my case DHS promised me they would bill it in their name, but they either lied or used the billing as a retaliatory tactic when I convinced (some) of the doctors to discharge me as the doctors had no medical basis on which to search me without consent. The bill itself was written by the private medical entities performing the search at direction of DHS.
