About T82.22

T82.22 is the ICD-10-CM diagnosis code for mechanical complication of biological heart valve graft. 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 4 subcodes must be used instead.

Within T82.2 (mechanical complication of coronary artery bypass graft and biological heart valve graft), T82.22 is specifically for mechanical complication of biological heart valve graft. Related codes cover coronary artery bypass graft (T82.21).

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.
