ICD-10-CMSalter-Harris Type III physeal fracture of phalanx of unspecified toe, subsequent encounter for fracture with nonunion
This code signifies a specific type of growth plate fracture (Salter-Harris Type III) affecting a phalanx bone in an unspecified toe. The fracture has progressed to a subsequent encounter where the bone fragments have failed to unite (nonunion). This indicates a complication in the healing process requiring further medical management.
Use this code for follow-up encounters where a patient previously diagnosed with a Salter-Harris Type III physeal fracture of a toe phalanx is found to have nonunion. This applies when the initial treatment has not resulted in bone healing and the patient is presenting for ongoing care related to this complication.
