Ask Dr. Z

Patient had a post-operative coronary sinus dissection that propagated to the posterior LA and IAS causing a large hematoma that was obstructing flow. The procedure performed was percutaneous drainage of a coronary sinus/left atrial hematoma and placement of a 35 mm Amplatzer Cribriform Occluder device in the left atrium, through the hematoma, and into the right atrium. I’m going to use unlisted code 93799 comparable to 93580 for the acquired ASD occlusion repair. However, would the percutaneous drainage of the atrial hematoma be inherent to the placement of the atrial occlude device, or can I bill it separately? If I can bill for the hematoma drainage separately, would it be an unlisted code?
