T82.09Other mechanical complication of heart valve prosthesis

T82.09 is the ICD-10-CM diagnosis code for other mechanical complication of heart valve prosthesis. It belongs to category T82 (complications of cardiac and vascular 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 T82.0, choose T82.09 (Other mechanical complication of heart valve prosthesis) only when documentation doesn't support a more specific option: breakdown (mechanical) of heart valve prosthesis (T82.01), displacement of heart valve prosthesis (T82.02) and leakage of heart valve prosthesis (T82.03).

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.
