S49.0Physeal fracture of upper end of humerus

S49.0 is the ICD-10-CM diagnosis code for physeal fracture of upper end of humerus. 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 (other and unspecified injuries of shoulder and upper arm), S49.0 is specifically for physeal fracture of upper end of humerus. Related codes cover physeal fracture of lower end of humerus (S49.1), other specified injuries of shoulder and upper arm (S49.8) and unspecified injury of shoulder and upper arm (S49.9).

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.
