S89.20Unspecified physeal fracture of upper end of fibula

S89.20 is the ICD-10-CM diagnosis code for unspecified physeal fracture of upper end of fibula. It belongs to category S89 (other and unspecified injuries of lower leg), block S80-S89 (injuries to the knee and lower leg) 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 S89.2, choose S89.20 (Unspecified physeal fracture of upper end of fibula) only when documentation doesn't support a more specific option: Salter-Harris Type I physeal fracture of upper end of fibula (S89.21), Salter-Harris Type II physeal fracture of upper end of fibula (S89.22) and other physeal fracture of upper end of fibula (S89.29).

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.
