Sltr-haris Type III physl fx lower end humer, unsp arm, 7thK

This code signifies a Salter-Harris Type III fracture affecting the growth plate at the distal humerus, specifically when the fracture has not healed and the patient is in a subsequent phase of care. This type of fracture involves a break through the physis and epiphysis, extending into the articular surface. The "unspecified arm" indicates laterality was not documented.

This code is appropriate for follow-up encounters where a previously diagnosed Salter-Harris Type III distal humeral fracture is documented as having nonunion. It should be used when the patient is receiving ongoing treatment for the unhealed fracture, such as cast changes, physical therapy, or preparation for surgical intervention to address the nonunion.

• Ensure documentation clearly states "nonunion" and "subsequent encounter" for this specific fracture type.
• Verify the fracture is indeed Salter-Harris Type III; differentiate from Types I, II, IV, or V.
• Confirm the anatomical site is the lower end of the humerus; do not use for other long bone physeal fractures.
