Ask Dr. Z

I'm having trouble trying to locate a CPT code that accurately captures this procedure. "A needle was used to attempt access of the lymphatic malformation in the left neck. Despite ultrasound images documenting needle position within a small cystic cavity inferior to the mandible, no fluid could be aspirated. A small amount of contrast agent was injected, which did not conform to the expected shape of the cavity. Therefore, no embolization was performed." Code 10160 seems like a possibility since he is accessing a cystic space of a lymphatic malformation, but I'm just not sure. And 36000 maybe for the injection of contrast?
