Ask Dr. Z

During EP studies, our provider documents "Hemostatic introducer sheaths were placed percutaneously in the left and right femoral veins using the modified Seldinger technique. Multipolar recording electrodes were advanced from the femoral veins to the right heart and into the coronary sinus for comprehensive study. Once the comprehensive study was done, atrial flutter and atrial fibrillation were induced with low-risk findings." Should pacing and recording in the RA, RV, and bundle of His be specified or is "right heart" sufficient documentation to support billing 93620 and 93621? Placement in RA, RV, and bundle of His are documented in the cath lab event log but this information is entered and signed by nursing staff.
