About S35.404

S35.404 is the ICD-10-CM diagnosis code for unspecified injury of right renal vein. 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 S35.40 (unspecified injury of renal blood vessel), S35.404 is specifically for unspecified injury of right renal vein. Related codes cover right renal artery (S35.401), left renal artery (S35.402), unspecified renal artery (S35.403), left renal vein (S35.405) and unspecified renal vein (S35.406).

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.
