Ask Dr. Z

"Following sterile preparation of the left lower neck, ultrasound imaging was performed to identify the left common carotid and left thyroid lobe. The pre-existing nasogastric tube was removed over a wire, and a 14 mm x 4 cm balloon was positioned in the low cervical esophagus. The balloon was inflated to nominal diameter and ultrasound utilized to direct a 21 gauge needle between the left common carotid and the left thyroid lobe into the balloon in the esophagus. The wire was coiled within the balloon lumen and advanced down the esophagus into the stomach. Over an Amplatz superstiff wire a 10.2 French 60 cm multipurpose drain was placed from the left cervical transesophageal approach into the gastric lumen. The catheter was sutured in place and attached to an external bag. No immediate procedural complications." Would I code this unlisted with 43999 and add 76000 for the fluoro and 76536 for the ultrasound?
