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

This code signifies a fracture of the lower end of the left radius, other than a Colles' or Smith's fracture, that has failed to heal properly after an initial treatment. The fracture is currently closed, meaning the skin over the bone is intact, but the bone fragments have not united.

This code is appropriate for follow-up encounters where a patient is being treated for a nonunion of a previously diagnosed, non-specific distal left radial fracture. It indicates that the fracture was initially closed and is still in a nonunion state.

• Always confirm the laterality (left) and the specific location (lower end of radius) of the fracture.
• Ensure documentation clearly states "nonunion" and that the fracture was initially closed.
• This code requires an additional code for any associated external causes or activity if applicable.
