What 61886 covers
A neurosurgeon typically places or replaces the implanted pulse generator or receiver and connects it to at least two previously placed or concurrently implanted electrode arrays. In deep brain stimulation, the generator is commonly placed in a subcutaneous pocket and linked by extensions to electrodes in the brain. The service may occur during an initial implant or a generator exchange when the existing array connections are retained or reconnected.
Select this code based on the number of electrode arrays connected to the generator, not the number of contacts on an array. The operative report should identify the generator work and document connection to two or more arrays. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose
- 61885Neurostimulator generator
- Use 61885 when the generator connects to one electrode array. Use 61886 when it connects to two or more.
- 61863Brain electrode placement
- This code describes electrode implantation, not generator placement or replacement. A case involving both services may support reporting both when each is performed and documented.
- 61888Neurostimulator surgery
- 61888 describes revision or removal of a neurostimulator receiver or generator; 61886 describes placing or replacing the generator with connections to two or more arrays.
- 61889Neurostimulator implant
- 61889 concerns a skull-mounted cranial neurostimulator system. 61886 describes a generator connected to two or more electrode arrays.
61886 billing questions
How does 61886 differ from 61885?
61886 is for a generator connected to two or more electrode arrays; 61885 is for connection to one array.
Can electrode-array placement be reported with 61886?
Array placement may be separately reported when performed and supported by the operative documentation. Codes such as 61863 or 61864 describe electrode implantation work, not generator placement.
Does 61886 include generator replacement?
Yes. It can describe placement or replacement of the generator when it is connected to two or more arrays. Revision or removal without generator placement or replacement is a different service.
What documentation supports 61886?
Document the generator placement or replacement and identify at least two electrode arrays connected to it. The record should distinguish this work from electrode implantation or revision.
Can modifier 50 be used for bilateral implantation?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
How does Medicare handle other procedures performed in the same session?
The highest-valued procedure is paid in full, with other procedures subject to the standard multiple procedure reduction. Assistant-at-surgery payment requires documented medical necessity.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
