About S49.139

S49.139 is the ICD-10-CM diagnosis code for Salter-Harris Type III physeal fracture of lower end of humerus, unspecified arm. It belongs to category S49 (other and unspecified injuries of shoulder and upper arm), block S40-S49 (injuries to the shoulder and upper arm) 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 S49.13, choose S49.139 (unspecified arm) only when documentation doesn't support a more specific option: right arm (S49.131) and left arm (S49.132).

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 changed in FY2017 (title revised).
