ICD-10-CMSalter-Harris Type II physeal fracture of phalanx of unspecified toe, subsequent encounter for fracture with malunion
This code signifies a Salter-Harris Type II fracture affecting the growth plate (physis) of an unspecified toe phalanx, which is currently in a stage of malunion. Malunion indicates that the fracture has healed, but in an anatomically incorrect or misaligned position. This specific type of physeal fracture involves the physis and a portion of the metaphysis.
Use this code for follow-up encounters where a previously diagnosed Salter-Harris Type II physeal fracture of an unspecified toe phalanx is now documented as having healed with malunion. This applies when the patient is receiving ongoing care, evaluation, or treatment for the consequences of this improperly healed fracture.
