Nondisp seg fx shaft of rad, r arm, 7thK

This code signifies a fracture of the radius bone in the right arm, specifically a segmental break in the shaft that has not displaced. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a typical healing period.

This code is appropriate for documenting ongoing treatment for a right radial shaft fracture where initial healing has not occurred. It applies when a patient presents for follow-up appointments, imaging, or interventions related to the persistent nonunion of this specific fracture type.

• Ensure documentation clearly specifies "right arm" and "segmental" fracture of the radial shaft.
• Verify the encounter is for follow-up care and not the initial treatment of the fracture.
• Confirm that the physician's notes explicitly state "nonunion" for the closed fracture.
