Sltr-haris Type IV physeal fx unspecified metatarsal, 7thK

This code signifies a complex growth plate fracture (Salter-Harris Type IV) affecting an unspecified metatarsal bone in the foot. The fracture extends through the physis, metaphysis, a portion of the epiphysis, and involves the articular surface. Importantly, this code is used when the fracture has not healed as expected and is now in a state of nonunion, requiring ongoing management.

Apply this code for follow-up encounters where a patient is being treated for a Salter-Harris Type IV fracture of an unspecified metatarsal that has failed to unite. This includes situations where the physician is assessing the nonunion, planning further interventions (e.g., bone grafting, revision surgery), or managing complications related to the lack of healing.

• Ensure documentation clearly specifies "nonunion" for the fracture.
• Verify the fracture is indeed Salter-Harris Type IV and involves a metatarsal.
• This code is for subsequent encounters; use the initial encounter code for the first visit.
