S85Injury of blood vessels at lower leg level

S85 is the ICD-10-CM diagnosis code for injury of blood vessels at lower leg level. It belongs to block S80-S89 (injuries to the knee and lower leg) 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S85.0 (artery), S85.1 (artery), S85.2 (artery), S85.3 (level), S85.4 (level), S85.5 (vein), S85.8 (level) and S85.9 (level).

The conditions in its Excludes2 note aren't part of S85, but may be coded alongside it if the patient has both: injury of blood vessels at ankle and foot level (S95.-).

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