Hello, This is for a ASC facility claim. There was a Spinal Cord Stimulator trial and two leads were suppose to be used for the trial, however the doctor was unable to advance the second lead after a two tries because of some anatomical issue. The doctor decided to go ahead with the SCS trial with one lead only. The one other lead was wasted. This was billed to medicare as 63650×1 and 63650 with modifier 74 times 1. The 63650 with modifier 74 did not pay. Was this billed correctly and what would be the best way to indicate a wasted lead?

Any help with this will be appreciated.
