About S91.2
S91.2 is the ICD-10-CM diagnosis code for open wound of toe with damage to nail. It belongs to category S91 (open wound of ankle, foot and toes), 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 6 subcodes must be used instead.
Within S91 (open wound of ankle, foot and toes), S91.2 is specifically for open wound of toe with damage to nail. Related codes cover ankle (S91.0), toe without damage to nail (S91.1) and foot (S91.3).
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.
