About S95.809

S95.809 is the ICD-10-CM diagnosis code for unspecified injury of other blood vessels at ankle and foot level, unspecified leg. It belongs to category S95 (injury of blood vessels at ankle and foot level), block S90-S99 (injuries to the ankle and foot) 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 S95.80, choose S95.809 (unspecified leg) only when documentation doesn't support a more specific option: right leg (S95.801) and left leg (S95.802).

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.
