"Missed abortion" charge for my IUD replacement under anesthesia

30F, BMI 21.8

I received an estimate today for a procedure I'm having done tomorrow - an IUD removal/insertion under anesthesia. Looking at the estimate, there are some entries that seem odd to me/not related to my procedure. For example, "Tx Missed Abortion First Trimester Surgical". There's also a charge for single source drugs from the pharmacy and it was not my understanding that I'd be sent home with medication - is this optional? Are these are naming conventions used for broad categories of procedures? Are they hypothetical charges and I'm being an estimate of all possible charges?

I reached out to billing and was told that they made the estimates based on the advice of the medical team. I'm planning on bringing the bill with me tomorrow to clarify these charges. But I also don't want to be annoying if this is a totally standard thing.

For clarification, the procedure is being done under anesthesia due to previous unsuccessful attempts at replacement. The cost after insurance on the estimate is $3000 (more than I expected, but fine if correct) so I want to make sure there hasn't been any mistake in the procedure and some of these charges are huge.
