I have a case where Surgeon A is performing a Lap Pyeloplasty and has asked Surgeon B to be in the OR for the Laparoscopy due to prior mesh placement by that surgeon (surgeon B).

Surgeon B has documentation of the initial laparoscopy and after they gain access and review mesh placement, etc Surgeon B leaves and Surgeon A finishes the case.

Is the work done by Surgeon B billable?

Thanks!
