About S99.112

S99.112 is the ICD-10-CM diagnosis code for Salter-Harris Type I physeal fracture of left metatarsal. It belongs to category S99 (other and unspecified injuries of ankle and foot), 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 S99.11 (Salter-Harris Type I physeal fracture of metatarsal), S99.112 is specifically for Salter-Harris Type I physeal fracture of left metatarsal. Related codes cover right metatarsal (S99.111) and unspecified metatarsal (S99.119).

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 was added in FY2017, effective October 1, 2016.
