Following the placement of a percutaneous SCS trial array/lead, the post op period would include 10 day period in which visits that could include removal of the array/lead, feedback from the patient of possible decrease in the pain level ("I feel better; my pain went from a 9 to a 5") or possible adverse response to having the temporary implanted lead ("I having an unfavorable response; I would like it removed")

In the April 2011 CPT Assistant, it is questioned whether 95971/95972 can be reported for temporary leads that have been attached to an external pulse generator. The AMA response was:
"An inherent portion of the lead placement and is not additionally reported using either code 95971 or 95972, is electronic analysis during a percutaneous electrod array placement (63650) or druing a laminerctomy for implantation of plate/paddle electrode array (63655) when only impendence testing an stimulation is performed to verify function of the leads (not the pulse generator)."
In December 2010 CPT Assistant, in regards to fluoroscopy reported in addition to percutaneously lead placement the AMA responded:
"Fluoroscopic guidance (codes 76000 and 77003) is considered inherent in the performance of the percutaneous implantation of the neurostimulator electrode array in the epidural space as represented by code 63650, Percutaneous implantation of neurostimulator electrode array, epidural. Therefore, it is not appropriate to additionally report the fluoroscopic guidance."
