About S85.13

S85.13 is the ICD-10-CM diagnosis code for unspecified injury of anterior tibial artery. It belongs to category S85 (injury of blood vessels at lower leg level), 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 3 subcodes must be used instead.

Within S85.1, choose S85.13 (Unspecified injury of anterior tibial artery) only when documentation doesn't support a more specific option: unspecified injury of unspecified tibial artery (S85.10), laceration of unspecified tibial artery (S85.11), other specified injury of unspecified tibial artery (S85.12), laceration of anterior tibial artery (S85.14), other specified injury of anterior tibial artery (S85.15), unspecified injury of posterior tibial artery (S85.16), laceration of posterior tibial artery (S85.17) and other specified injury of posterior tibial artery (S85.18).

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.
