T84.1Mechanical complication of internal fixation device of bones of limb

T84.1 is the ICD-10-CM diagnosis code for mechanical complication of internal fixation device of bones of limb. It belongs to category T84 (complications of internal orthopedic 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 T84 (complications of internal orthopedic prosthetic devices, implants and grafts), T84.1 is specifically for mechanical complication of internal fixation device of bones of limb. Related codes cover mechanical complication of internal joint prosthesis (T84.0), mechanical complication of internal fixation device of other bones (T84.2), mechanical complication of other bone devices, implants and grafts (T84.3), mechanical complication of other internal orthopedic devices, implants and grafts (T84.4), infection and inflammatory reaction due to internal joint prosthesis (T84.5), infection and inflammatory reaction due to internal fixation device (T84.6), infection and inflammatory reaction due to other internal orthopedic prosthetic devices, implants and grafts (T84.7), other specified complications of internal orthopedic prosthetic devices, implants and grafts (T84.8) 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.

The conditions in its Excludes2 note aren't part of T84.1, but may be coded alongside it if the patient has both: mechanical complication of internal fixation device of bones of feet (T84.2-), mechanical complication of internal fixation device of bones of fingers (T84.2-), mechanical complication of internal fixation device of bones of hands (T84.2-) and mechanical complication of internal fixation device of bones of toes (T84.2-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
