Ask Dr. Z

"On day 2 of thrombolysis to right leg from EIV to popliteal vein, the physician removed the EKOS catheter and performed inferior cavogram and right lower extremity venogram followed by mechanical thrombectomy to CFV, EIV and CIV. Venogram was repeated and showed minimal clot and stenosis in CIV, EIV, and CFV. Balloon angioplasty and stents were placed in the CFV and EIV. Repeat IVUS performed and showed stenosis in the EIV above the stent. A single 18 mm x 80 mm Wallstent was used to across CIV, EIV and CFV without any extension into IVC."

I have coded 37187, 37214, 37238, 37239 x2, 37252, 37253 x2, 75825, and 75820-RT. Are RLE venogram and inferior cavogram billable with the additional interventions?
