S92.313Displaced fracture of first metatarsal bone, unspecified foot

S92.313 is the ICD-10-CM diagnosis code for displaced fracture of first metatarsal bone, unspecified foot. 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 7 subcodes must be used instead.

Within S92.31, choose S92.313 (Displaced fracture of first metatarsal bone, unspecified foot) only when documentation doesn't support a more specific option: displaced fracture of first metatarsal bone, right foot (S92.311), displaced fracture of first metatarsal bone, left foot (S92.312), nondisplaced fracture of first metatarsal bone, right foot (S92.314), nondisplaced fracture of first metatarsal bone, left foot (S92.315) and nondisplaced fracture of first metatarsal bone, unspecified foot (S92.316).

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.
