Ask Dr. Z

Are codes 47382 and 47540 appropriate for the following? 

"Contrast was injected to fill the right-sided biliary system. Under fluoroscopic guidance, a 21 gauge needle was advanced in a peripheral right-sided biliary duct. A vascular sheath was then placed. Angled catheter and Glidewire were used to pass the stricture and gain access into the duodenum. Stiff wires were then placed. Endo biliary RFA was then performed from both the right and the left sides. A 7 x 80 and a 9 x 80 LifeStar uncovered stent were then deployed from the right and left sides. Post stent placement cholangiogram was performed. Two 10 French long biliary drains were then placed. The drains were secured in place. The patient tolerated the procedure well with no complications. FINDINGS: Cholangiogram from the left-sided access demonstrates severe stricturing at the biliary hilum consistent with the patient's history. Impression: Endo biliary radiofrequency ablation with bilateral biliary stents and bilateral biliary drain placement."
