What 64590 covers
This service places or replaces the implanted power unit that drives a peripheral, sacral, or gastric neurostimulator. The surgeon or other qualified proceduralist typically creates or reopens a pocket, positions the generator or receiver, and connects it to the implanted electrode array. Examples include generator replacement for a patient receiving sacral neuromodulation for urinary or bowel symptoms, or for gastric stimulation for gastroparesis. The work is commonly performed in an operating room or procedure facility; the generator procedure is distinct from placing or revising the nerve electrode.
Report this code when the implanted generator or receiver is inserted or replaced, not for lead work alone. The operative report should identify the device, the reason for insertion or replacement, the pocket and connection work, and any electrode-array procedure performed. Medicare includes related postoperative visits for 10 days. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this service. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team-surgery billing is not permitted.

64590 billing questions
How is this different from 64595?
64590 is for inserting or replacing the generator or receiver. Use 64595 when the generator or receiver is revised or removed without insertion or replacement.
Does this code include placement of the electrode array?
No. This code represents generator or receiver work; electrode-array placement, revision, or removal is a separate service when performed and supported by the operative documentation.
Can it be reported with a sacral electrode-array code?
It may be reported with 64561 or 64581 when the electrode array and implanted generator are placed during the same permanent implantation encounter. The record should describe both services.
What documentation supports generator replacement?
Document the existing device and its indication, why replacement was performed, the generator or receiver work, and its connection to the electrode array.
Should modifier 50 be used for bilateral treatment?
No. Modifier 50 is inappropriate for this generator or receiver service.
Are postoperative visits included?
Related postoperative visits during the 10-day global period are included in the service.
