Wiki Omaya Reservoir Revision?

From AANS:

Revision of an Ommaya Reservoir

Q: I have revised an Ommaya reservoir by placing it in better proximity to the intracranial cyst. The catheter had been previously placed by an outside surgeon. What is the best code?

A:
Ommaya reservoirs are appropriately billed using a 61210 (Burr hole for implanting of a ventricular catheter, reservoir, EEG electrode(s), pressure recording device, or other cerebral monitoring device). As the physician work in this case is being replicated (revision of the catheter and reservoir), 61210 is appropriate. Navigation (+61781) can be used if documented. Removal of an Ommaya is listed as unlisted procedure (64999).
