Unsp fx the lower end unsp rad, subs for clos fx w malunion

This code signifies a follow-up encounter for a fracture of the lower part of the radius, where the specific type of fracture is not documented. The fracture has been treated non-surgically (closed) but has healed in an unsatisfactory position, leading to a deformity or functional impairment (malunion).

Use this code when a patient presents for ongoing management or evaluation of a previously treated, unspecified distal radius fracture that has healed with malunion, and the initial treatment was non-operative. This applies to situations where the specific bone involved is the radius, but the exact location or type of fracture within the lower end is not specified in the medical record.

• Ensure documentation clearly indicates a "subsequent encounter" and "malunion" for a closed fracture.
• Verify that the fracture location is documented as the "lower end of the radius" but lacks further specificity.
• Always look for more specific codes if the type of fracture (e.g., Colles', Smith's) or laterality (left/right) is documented.
