S95.90Unspecified injury of unspecified blood vessel at ankle and foot level

S95.90 is the ICD-10-CM diagnosis code for unspecified injury of unspecified blood vessel at ankle and foot level. 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 S95.9, choose S95.90 (Unspecified injury of unspecified blood vessel at ankle and foot level) only when documentation doesn't support a more specific option: laceration of unspecified blood vessel at ankle and foot level (S95.91) and other specified injury of unspecified blood vessel at ankle and foot level (S95.99).

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.
