S35.3Injury of portal or splenic vein and branches

S35.3 is the ICD-10-CM diagnosis code for injury of portal or splenic vein and branches. 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 (injury of blood vessels at abdomen, lower back and pelvis level), S35.3 is specifically for injury of portal or splenic vein and branches. Related codes cover abdominal aorta (S35.0), inferior vena cava (S35.1), celiac or mesenteric artery and branches (S35.2), renal blood vessels (S35.4), iliac blood vessels (S35.5), other blood vessels at abdomen, lower back and pelvis level (S35.8) and unspecified blood vessel at abdomen, lower back and pelvis level (S35.9).

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.

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