About S89.321

S89.321 is the ICD-10-CM diagnosis code for Salter-Harris Type II physeal fracture of lower end of right 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 6 subcodes must be used instead.

Within S89.32 (Salter-Harris Type II physeal fracture of lower end of fibula), S89.321 is specifically for Salter-Harris Type II physeal fracture of lower end of right fibula. Related codes cover left fibula (S89.322) and unspecified fibula (S89.329).

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.
