Oth fx of lower end unsp radius, subs for clos fx w nonunion

This code signifies a fracture in the lower part of the radius bone, where the specific location within the lower end is not documented. It indicates that the patient is returning for follow-up care of a fracture that has not healed properly (nonunion) and the skin over the fracture site remains intact (closed).

This code is appropriate for subsequent encounters when a patient presents with a previously diagnosed, unspecified fracture of the distal radius that has failed to unite. It should be used when the fracture is closed and the physician is managing the nonunion, such as during evaluation for bone grafting or other surgical interventions to promote healing.

• Ensure documentation clearly states "nonunion" and "closed fracture" for the lower end of the radius.
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Do not use this code if the specific part of the lower radius (e.g., Colles', Smith's) is documented; use a more specific code.
