About T85.190

T85.190 is the ICD-10-CM diagnosis code for other mechanical complication of implanted electronic neurostimulator of brain electrode (lead). It belongs to category T85 (complications of other internal prosthetic devices, implants and grafts), block T80-T88 (complications of surgical and medical care, not elsewhere classified) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T85.19 (other mechanical complication of implanted electronic stimulator of nervous system), T85.190 is specifically for other mechanical complication of implanted electronic neurostimulator of brain electrode (lead). Related codes cover implanted electronic neurostimulator of peripheral nerve electrode (lead) (T85.191), implanted electronic neurostimulator of spinal cord electrode (lead) (T85.192), implanted electronic neurostimulator, generator (T85.193) and other implanted electronic stimulator of nervous system (T85.199).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).
