4-part fx surg neck of r humerus, subs for fx w delay heal

This code signifies a complex fracture involving four distinct fragments of the upper part of the right humerus, specifically at the surgical neck. The "subsequent encounter" indicates that the patient is receiving ongoing care for this fracture, and "delayed healing" specifies that the bone is not mending at the expected rate.

This code is appropriate for follow-up visits where a patient with a previously diagnosed 4-part surgical neck fracture of the right humerus is being monitored or treated for slow or impaired bone union. This would include scenarios such as cast changes, physical therapy evaluations, or surgical interventions aimed at promoting healing, when delayed healing has been documented.

• Ensure documentation clearly specifies "4-part" and "surgical neck" to support this specific fracture type.
• Verify that "delayed healing" is explicitly stated by the provider, not just inferred from prolonged treatment.
• Confirm the encounter is for follow-up care, not the initial treatment of the acute fracture.
