I do offsite coding for several radiology groups. All of the groups bill for the insertion of a PICC line (catheter placement) so the patient can receive antibiotics. I have always coded the reason the patient needs antibiotics (if it's noted on the report) with V58.62 as secondary for long-term antibiotics. If no reason listed, I code V58.62 as primary.
Is this correct since it is for long-term antibiotics or should I be using V58.81?
