I code for an ASC, yesterday ,we had a pain mgmt physician who stated that he was doing a "revision" on a permanent spinal cord stimulator. In reading his op note, today, he performed a replacement of electrodes for spinal cord stimulator x3. Have I interpreted the code correctly? as code 63663 states revision including replacement , when performed, of spinal cord neurostimulator electrode percutaneous array(s) including fluro, when performed. I understand this for the leads to be inclusive.Am I interpreting this correctly? by the way the patient is a Medicare patient. I am currently coding this :

Any and all input is appreciated.
Thank you
