Smith's fracture of r radius, subs for clos fx w nonunion

This code signifies a specific type of distal radius fracture, a Smith's fracture, affecting the right arm. It indicates that the patient is in a later phase of treatment for this fracture, and a complication of nonunion (failure of the bone to heal) has been identified, with the fracture remaining closed.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed and treated Smith's fracture of the right radius presents with evidence of nonunion. This would typically occur after initial casting or surgical intervention, when imaging studies confirm the lack of bony healing. It is used when the fracture site has not broken through the skin.

• Ensure documentation clearly specifies "Smith's fracture" and "right radius" to support code assignment.
• Verify that the encounter is for subsequent care and that nonunion is explicitly documented as a complication.
• Confirm the fracture is closed; if open, a different seventh character would be required.
