Unfortunately it is so common ACLU had to send a warning to a long list of hospitals CBP works with [0] to do this kind of thing as part of a lawsuit [1]. They still haven't stopped and the hospitals continue the searches, in fact I was sent to one of the hospitals listed.
A woman (who they never even got a warrant for and nothing found) at the hospital I was at was forcefully penetrated in a pretty disgusting way and I'm unaware of any significant remedy for her despite a lawsuit [2]. The lawyer who took her case told me they'd given up on such cases when I spoke with them. I complained to the relevant medical state board and they basically said everything is kosher.
While in the hospital with officers, I had the opportunity to ask them about their history in regard to this behavior. They bragged to me of various nefarious activity, such as taking someone in because they had a trans female-to-male "appendage" so they accused it of being a drug smuggling apparatus apparently to fuck with them. It was clear to me in these discussions it is routine and common behavior, and they voiced to me it was profitable for them as they commonly were paid a very high overtime wage to sit in the hospital which is easy work compared to their normal job at the port of entry and allows them to buy expensive trucks.
2 (relevant details start bottom page 6) is a pretty brutal read.
