Sltr-haris Type IV physl fx low end ulna, r arm, 7thK

This code signifies a complex growth plate fracture at the lower end of the right ulna, specifically a Salter-Harris Type IV, which involves both the epiphysis and metaphysis. Crucially, this code is used when the fracture has failed to heal properly, resulting in a nonunion, and the patient is receiving follow-up care for this complication.

Apply this code for a patient presenting for ongoing treatment of a right distal ulnar Salter-Harris Type IV fracture that has been previously diagnosed and is now complicated by nonunion. This would include scenarios such as follow-up appointments for casting, bracing, physical therapy, or surgical planning related to the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" as the complication of the fracture.
• Verify the fracture type is explicitly documented as Salter-Harris Type IV and the location is the lower end of the ulna on the right arm.
• Confirm this is a subsequent encounter for care related to the nonunion, not the initial treatment.
