S92.4Fracture of great toe

S92.4 is the ICD-10-CM diagnosis code for fracture of great toe. It belongs to category S92 (fracture of foot and toe, except ankle), 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 4 subcodes must be used instead.

Within S92 (fracture of foot and toe, except ankle), S92.4 is specifically for fracture of great toe. Related codes cover fracture of calcaneus (S92.0), fracture of talus (S92.1), fracture of other and unspecified tarsal bone(s) (S92.2), fracture of metatarsal bone(s) (S92.3), fracture of lesser toe(s) (S92.5), other fracture of foot, except ankle (S92.8) and unspecified fracture of foot and toe (S92.9).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion, P for subsequent encounter for fracture with malunion and 1 more. Use placeholder "X" characters to fill any empty positions before the 7th character.

The conditions in its Excludes2 note aren't part of S92.4, but may be coded alongside it if the patient has both: Physeal fracture of phalanx of toe (S99.2-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
