T82.4Mechanical complication of vascular dialysis catheter
T82.4 is a header code, so it can't be reported by itself. Choose one of the 4 more specific codes beneath it and add the required 7th character.

About T82.4
T82.4 is the ICD-10-CM diagnosis code for mechanical complication of vascular dialysis catheter. 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 (complications of cardiac and vascular prosthetic devices, implants and grafts), T82.4 is specifically for mechanical complication of vascular dialysis catheter. Related codes cover mechanical complication of heart valve prosthesis (T82.0), mechanical complication of cardiac electronic device (T82.1), mechanical complication of coronary artery bypass graft and biological heart valve graft (T82.2), mechanical complication of other vascular grafts (T82.3), mechanical complication of other cardiac and vascular devices and implants (T82.5), infection and inflammatory reaction due to cardiac valve prosthesis (T82.6), infection and inflammatory reaction due to other cardiac and vascular devices, implants and grafts (T82.7), other specified complications of cardiac and vascular prosthetic devices, implants and grafts (T82.8) 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.
Don't report T82.4 together with the conditions in its Excludes1 note: mechanical complication of intraperitoneal dialysis catheter (T85.62).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
