Sltr-haris Type III physl fx low end ulna, unsp arm, 7thK

This code signifies a specific type of growth plate fracture (Salter-Harris Type III) affecting the lower portion of the ulna bone. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient is being managed for a previously diagnosed Salter-Harris Type III physeal fracture of the distal ulna that has developed a nonunion. This would include visits for monitoring the nonunion, planning further intervention, or managing complications related to the unhealed fracture.

• Ensure documentation clearly specifies a Salter-Harris Type III fracture and confirms nonunion.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Laterality (left or right arm) is unspecified in this particular code; use a more specific code if documented.
