About T84.623

T84.623 is the ICD-10-CM diagnosis code for infection and inflammatory reaction due to internal fixation device of left tibia. 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 T84.62 (infection and inflammatory reaction due to internal fixation device of leg), T84.623 is specifically for infection and inflammatory reaction due to internal fixation device of left tibia. Related codes cover right femur (T84.620), left femur (T84.621), right tibia (T84.622), right fibula (T84.624), left fibula (T84.625) and unspecified bone of leg (T84.629).

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.
