Displ oblique fx shaft of l rad, subs for clos fx w nonunion

This code describes a specific type of fracture involving the shaft of the left radius, characterized by an oblique break that is displaced. Importantly, it indicates that the fracture has not healed properly (nonunion) and the patient is in a subsequent phase of care for this closed fracture.

Use this code for follow-up encounters for patients with a previously diagnosed displaced oblique fracture of the left radial shaft that has failed to unite. This applies when the fracture is closed and the patient is receiving ongoing treatment for the nonunion.

• Ensure documentation specifies "left radius" and "shaft" for accurate laterality and location.
• Confirm the fracture is explicitly documented as "displaced," "oblique," and "nonunion."
• Verify the encounter is for subsequent care of a closed fracture, not an initial treatment or an open fracture.
