T79Certain early complications of trauma, not elsewhere classified

T79 is the ICD-10-CM diagnosis code for certain early complications of trauma, not elsewhere classified. It belongs to block T79 (certain early complications of trauma) 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: T79.0 ((traumatic)), T79.1 ((traumatic)), T79.2 (seroma), T79.4 (shock), T79.5 (anuria), T79.6 (muscle), T79.7 (emphysema), T79.8 (trauma) and 2 more.

The conditions in its Excludes2 note aren't part of T79, but may be coded alongside it if the patient has both: acute respiratory distress syndrome (J80), complications occurring during or following medical procedures (T80-T88), complications of surgical and medical care NEC (T80-T88) and newborn respiratory distress syndrome (P22.0).

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