I've been coding for many years but no OB/GYN experience - billing service I'm working with has GYN billing 99000 for PAP. When I questioned this after reading CPT definition I was told they have several clients who use this code for Paps. It seems clear to me that this code is strickly for getting the pap packed up AND TO THE LAB, am I wrong? Is there a Coding Edge article or other reference I can physically use to back myself up?????? Thanks.
