About T85.8

T85.8 is the ICD-10-CM diagnosis code for other specified complications of internal prosthetic devices, implants and grafts, not elsewhere classified. 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 7 subcodes must be used instead.

Within T85, choose T85.8 (Other specified complications of internal prosthetic devices, implants and grafts, not elsewhere classified) only when documentation doesn't support a more specific option: mechanical complication of ventricular intracranial (communicating) shunt (T85.0), mechanical complication of implanted electronic stimulator of nervous system (T85.1), mechanical complication of intraocular lens (T85.2), mechanical complication of other ocular prosthetic devices, implants and grafts (T85.3), mechanical complication of breast prosthesis and implant (T85.4), mechanical complication of gastrointestinal prosthetic devices, implants and grafts (T85.5), mechanical complication of other specified internal and external prosthetic devices, implants and grafts (T85.6), infection and inflammatory reaction due to other internal prosthetic devices, implants and grafts (T85.7) and 1 more.

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 hasn't changed since.
