Use of 37184/37185

Date: Dec 15, 2021

Question:

Can you provide clarification on how to use 37184 and 37185? Should 37184-50 be used for each initial vessel (both the right and left pulmonary artery) and then 37185 would be used for the second or subsequent vessels entered (example if the right pulmonary artery was entered it would be 37184 and then catheter was moved into the lower lobe of right pulmonary and 37185 would be used)? Or 37184 is used for the initial vessel entered, say, the right pulmonary artery 37184 and then the left pulmonary artery would be 37185?
