About T81.71

T81.71 is the ICD-10-CM diagnosis code for complication of artery following a procedure, not elsewhere classified. It belongs to category T81 (complications of procedures, not elsewhere classified), 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 T81.7 (vascular complications following a procedure, not elsewhere classified), T81.71 is specifically for complication of artery following a procedure, not elsewhere classified. Related codes cover vein following a procedure, not elsewhere classified (T81.72).

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.

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
