Cholecystostomy placement and replacement same day

Date: Dec 1, 2023

Question:

Under CT guidance, cholecystostomy was placed. This was a 8 French locking drain. At the conclusion, the GB drain was at the GB margin. Sideholes were outside of the GB lumen. We were unsuccessful in repositioning in CT. Patient was taken to specials and under fluro the drain was removed. Yueh centesis catheter was placed over the guidewire and contrast injected into the gallbladder. Showed filling of the GB lumen showing irregular luminal features compatible w/gangrenous cholecystitis. There was filling of the cystic duct and partial opacification of the CHD. A new 8 French locking drain was placed over the guidewire and a more desirable position within the GB. The catheter was secured to the skin.

How would I code this? Do we charge 47490 with the exchange/replacement 47536?
