About T82.855
T82.855 is the ICD-10-CM diagnosis code for stenosis of coronary artery stent. 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 T82.85 (stenosis due to cardiac and vascular prosthetic devices, implants and grafts), T82.855 is specifically for stenosis of coronary artery stent. Related codes cover peripheral vascular stent (T82.856), other cardiac prosthetic devices, implants and grafts (T82.857) and other vascular prosthetic devices, implants and grafts (T82.858).
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 was added in FY2017, effective October 1, 2016.
