About T85.321

T85.321 is the ICD-10-CM diagnosis code for displacement of prosthetic orbit of left eye. 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 T85.32 (displacement of other ocular prosthetic devices, implants and grafts), T85.321 is specifically for displacement of prosthetic orbit of left eye. Related codes cover prosthetic orbit of right eye (T85.320) and other ocular prosthetic devices, implants and grafts (T85.328).

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.
