S35.239Unspecified injury of inferior mesenteric artery

S35.239 is the ICD-10-CM diagnosis code for unspecified 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 3 subcodes must be used instead.

Within S35.23, choose S35.239 (Unspecified injury of inferior mesenteric artery) only when documentation doesn't support a more specific option: minor laceration of inferior mesenteric artery (S35.231), major laceration of inferior mesenteric artery (S35.232) and other injury of inferior mesenteric artery (S35.238).

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.
