S92.40Unspecified fracture of great toe

S92.40 is the ICD-10-CM diagnosis code for unspecified 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 6 subcodes must be used instead.

Within S92.4, choose S92.40 (Unspecified fracture of great toe) only when documentation doesn't support a more specific option: fracture of proximal phalanx of great toe (S92.41), fracture of distal phalanx of great toe (S92.42) and other fracture of great toe (S92.49).

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.

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