About S35.23

S35.23 is the ICD-10-CM diagnosis code for injury of inferior mesenteric artery. It belongs to category S35 (injury of blood vessels at abdomen, lower back and pelvis level), block S30-S39 (injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals) 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 S35.2 (injury of celiac or mesenteric artery and branches), S35.23 is specifically for injury of inferior mesenteric artery. Related codes cover celiac artery (S35.21), superior mesenteric artery (S35.22) and branches of celiac and mesenteric artery (S35.29).

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