Question: Delay in debt appearing on credit card statement
Answer: If the hospital is run like hospitals in the US it can take a long time just to determine the bill. The hospital, Emergency room, ER doctors, surgeons, anesthesiologists, X-Ray department, pharmacy and laboratory are considered separate billing centers. It  can take a while to determine the charges for each section.

Is there an insurance company involved? When there is one involved it can take weeks or months before the hospital determines what the individual owes. The co-pays, coverages, and limits can be very confusing.

In my experience it can take a few months before the final amount is known.

You may want to call the hospital to determine the status of the bills.
