Ventriculo-peritoneal / ventriculo-atrial shunt is for removing the excess CSF from brain ventricles and to move them to peritoneal space, atrial area or any other body cavity to reduce the extra pressure from brain. The creation of CSF shunt system is coded with 62220 / 62223. Using 62223 is more frequent while coding.the code for revision is 62230. Since the Px in question says that it’s for revision only and not for creation, 62230 is correct.
The MPFS in SC suggests that this code is approved for modifier 62. The modifier indicator applicable here is 1 which says – “Co-surgeons could be paid, but supporting documentation is required to establish the medical necessity of two surgeons for the procedure.”
