About S89.1

S89.1 is the ICD-10-CM diagnosis code for physeal fracture of lower end of tibia. 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 (other and unspecified injuries of lower leg), S89.1 is specifically for physeal fracture of lower end of tibia. Related codes cover physeal fracture of upper end of tibia (S89.0), physeal fracture of upper end of fibula (S89.2), physeal fracture of lower end of fibula (S89.3), other specified injuries of lower leg (S89.8) and unspecified injury of lower leg (S89.9).

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.
