About T81.7

T81.7 is the ICD-10-CM diagnosis code for vascular complications 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 2 subcodes must be used instead.

Within T81 (complications of procedures, not elsewhere classified), T81.7 is specifically for vascular complications following a procedure, not elsewhere classified. Related codes cover postprocedural shock (T81.1), disruption of wound, not elsewhere classified (T81.3), infection following a procedure (T81.4), complications of foreign body accidentally left in body following procedure (T81.5), acute reaction to foreign substance accidentally left during a procedure (T81.6), other complications of procedures, not elsewhere classified (T81.8) and unspecified complication of procedure (T81.9).

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 T81.7 together with the conditions in its Excludes1 note: embolism complicating abortion or ectopic or molar pregnancy (O00-O07, O08.2), embolism complicating pregnancy, childbirth and the puerperium (O88.-) and traumatic embolism (T79.0).

The conditions in its Excludes2 note aren't part of T81.7, but may be coded alongside it if the patient has both: embolism due to prosthetic devices, implants and grafts (T82.8-, T83.81, T84.8-, T85.81-) and embolism following infusion, transfusion and therapeutic injection (T80.0).

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.
