S59.249Salter-Harris Type IV physeal fracture of lower end of radius, unspecified arm

S59.249 is the ICD-10-CM diagnosis code for Salter-Harris Type IV physeal fracture of lower end of radius, unspecified arm. It belongs to category S59 (other and unspecified injuries of elbow and forearm), block S50-S59 (injuries to the elbow and forearm) 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 S59.24, choose S59.249 (unspecified arm) only when documentation doesn't support a more specific option: right arm (S59.241) and left arm (S59.242).

Codes in this range require a 7th character: A for initial encounter for closed 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 S for sequela. 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.
