"Percutaneous entry with a 6 French sheath placed in right femoral vein and 6 French sheath in right femoral artery. A 6 French wedge catheter was advanced to right heart, and a pressure and saturation sweep was performed. Angled Glidecaths were used to complete the right heart cath. A careful pullback from the LV to descending aorta was performed using a pigtail. The Glidecath was advanced to the innominate vein with hand injection performed, demonstrating the veno-venous collateral. Over a wire the Glidecath was exchanged for a 5 French JR guiding catheter and advanced into the veno-venous collateral, and a 4 mm AVP II was selected and advanced to the venous collateral and device was released. Hemodynamics list: Hep Vwedge, SVC, IVC,RPA, LPA, LV , AAO, DAO, Fontan pressures, transhepatic gradient of 2 mmHg. Cineangiograms lists Hemi-azygous and collateral 1 hand injections." Does 36012 x 2 describe the further selections? Was hepatic wedge pressure performed? Do we need angiography codes 75889, 75605?
