Bent bone of l rad, subs for opn fx type 3A/B/C w malunion

This code describes a left radial shaft fracture that has healed in an abnormal alignment (malunion) and was initially an open fracture of severe complexity (Type IIIA, IIIB, or IIIC). The patient is currently receiving follow-up care for this previously treated injury.

This code is appropriate for subsequent encounters when a patient presents with complications or requires ongoing management related to a malunited open fracture of the left radial shaft. This includes scenarios such as physical therapy, cast changes, or evaluation for corrective osteotomy after the initial healing phase.

• Ensure documentation specifies "malunion" and not "nonunion" or "delayed union."
• Verify the initial fracture was an open fracture type IIIA, IIIB, or IIIC.
• Confirm the encounter is for follow-up care, not initial treatment or active healing of an acute fracture.
