What 64595 covers
This service addresses the implanted pulse generator or receiver for a sacral neuromodulation system or a gastric electrical stimulation system. The surgeon may revise the generator or remove it; the work concerns the generator or receiver, not the electrode array. Typical cases include correcting a generator pocket problem or removing a failed or no-longer-needed generator. Urologic, colorectal, or foregut surgeons commonly perform these procedures in a procedural or operating-room setting. Device analysis, programming, and imaging are included when performed as part of the service.
Choose this code when the operative work is revision or removal, rather than insertion or replacement of the generator. Document the device type and site, the reason for surgery, and the generator work performed. CMS assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

64595 billing questions
When should I report 64595 instead of 64590?
Report 64595 for revision or removal of the sacral or gastric system’s generator or receiver. Report 64590 when the generator or receiver is inserted or replaced.
Does this code cover work on the electrode array?
No. The service concerns the generator or receiver. If the operative work revises or removes a separate peripheral neurostimulator electrode array, consider 64585 instead.
Can device analysis, programming, or imaging be billed separately?
Analysis, programming, and imaging are included when performed as part of this generator revision or removal service.
Should I append modifier 50 for bilateral work?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
Are an assistant surgeon or co-surgeons payable?
Medicare does not pay an assistant at surgery for 64595. Co-surgeons and team surgery are not permitted.
How does the global period affect postoperative visits?
The code has a 10-day global period. Related postoperative visits during those 10 days are included.
