S45Injury of blood vessels at shoulder and upper arm level

S45 is the ICD-10-CM diagnosis code for injury of blood vessels at shoulder and upper arm level. It belongs to block S40-S49 (injuries to the shoulder and upper arm) 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S45.0 (artery), S45.1 (artery), S45.2 (vein), S45.3 (level), S45.8 (level) and S45.9 (level).

The conditions in its Excludes2 note aren't part of S45, but may be coded alongside it if the patient has both: injury of subclavian artery (S25.1) and injury of subclavian vein (S25.3).

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