S91.151Open bite of right great toe without damage to nail

S91.151 is the ICD-10-CM diagnosis code for open bite of right great toe without 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 S91.15, choose S91.151 (right great toe without damage to nail) only when documentation doesn't support a more specific option: left great toe without damage to nail (S91.152), unspecified great toe without damage to nail (S91.153), right lesser toe(s) without damage to nail (S91.154), left lesser toe(s) without damage to nail (S91.155), unspecified lesser toe(s) without damage to nail (S91.156) and unspecified toe(s) without damage to nail (S91.159).

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.
