About S79.01

S79.01 is the ICD-10-CM diagnosis code for Salter-Harris Type I physeal fracture of upper end of femur. It belongs to category S79 (other and unspecified injuries of hip and thigh), block S70-S79 (injuries to the hip and thigh) 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 3 subcodes must be used instead.

Within S79.0 (physeal fracture of upper end of femur), S79.01 is specifically for Salter-Harris Type I physeal fracture of upper end of femur. Related codes cover unspecified physeal fracture of upper end of femur (S79.00) and other physeal fracture of upper end of femur (S79.09).

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.

Don't report S79.01 together with the conditions in its Excludes1 note: chronic slipped upper femoral epiphysis (nontraumatic) (M93.02-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
