S35.9Injury of unspecified blood vessel at abdomen, lower back and pelvis level

S35.9 is the ICD-10-CM diagnosis code for injury of unspecified blood vessel at abdomen, lower back and pelvis level. 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, choose S35.9 (unspecified blood vessel at abdomen, lower back and pelvis level) only when documentation doesn't support a more specific option: abdominal aorta (S35.0), inferior vena cava (S35.1), celiac or mesenteric artery and branches (S35.2), portal or splenic vein and branches (S35.3), renal blood vessels (S35.4), iliac blood vessels (S35.5) and other blood vessels at abdomen, lower back and pelvis level (S35.8).

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.
