ICD-10-CMSalter-Harris Type II physeal fracture of phalanx of unspecified toe, subsequent encounter for fracture with nonunion
This code signifies a Salter-Harris Type II fracture affecting the growth plate of an unspecified toe's phalanx, specifically when the fracture has failed to heal properly and the patient is receiving ongoing care for this nonunion. This type of fracture involves the growth plate and a portion of the metaphysis.
Apply this code for patients presenting for follow-up care, cast changes, or further treatment (e.g., surgical intervention) for a previously diagnosed Salter-Harris Type II physeal fracture of an unspecified toe phalanx that has not united. This indicates the fracture has not healed within the expected timeframe and requires continued management.
