I recently had a discussion with a CRNA about Pain Management. The Doctor would code Cervical ESI and I would code 62310. Could someone tell me if this is the correct code to use. Also we use alot of CRNA's and our system is set up for concurrency, so I have to do what they call batch billing which puts the anesthesiologist as the Supervisor and the CRNA the Supervisoree. If the insurance company accepts concurrency, then the system will break out a seperate charge for the CRNA with a QK modifier. When the physician performs a 29827 and then a 64415 and uses the CRNA for the main case, should a seperate bill be submitted for just the physician alone for the 64415 and if so what diagnosis should be used?
