I've never had to do this before from a patient standpoint, but perhaps you could try to find out what codes were billed for the visit. [1] Compare this to what was actually performed. It is possible they upcoded your visit, either inadvertently or on purpose (illegally.)

Aside from that, (EDIT: More likely) it could also be that lots of billing actually takes place when a coder reviews the doctor's note of the encounter. This can be several days after the visit. This is a legitimate and very common practice. They might not have known the correct amount to charge until everything was properly coded.
