About S99.2
S99.2 is the ICD-10-CM diagnosis code for physeal fracture of phalanx of toe. 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 6 subcodes must be used instead.
Within S99 (other and unspecified injuries of ankle and foot), S99.2 is specifically for physeal fracture of phalanx of toe. Related codes cover physeal fracture of calcaneus (S99.0), physeal fracture of metatarsal (S99.1), other specified injuries of ankle and foot (S99.8) and unspecified injury of ankle and foot (S99.9).
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.
It was added in FY2017, effective October 1, 2016.
