S91.236Puncture wound without foreign body of unspecified lesser toe(s) with damage to nail

S91.236 is the ICD-10-CM diagnosis code for puncture wound without foreign body of unspecified lesser toe(s) 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 3 subcodes must be used instead.

Within S91.23, choose S91.236 (unspecified lesser toe(s) with damage to nail) only when documentation doesn't support a more specific option: right great toe with damage to nail (S91.231), left great toe with damage to nail (S91.232), unspecified great toe with damage to nail (S91.233), right lesser toe(s) with damage to nail (S91.234), left lesser toe(s) with damage to nail (S91.235) and unspecified toe(s) with damage to nail (S91.239).

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.
