Bent bone of unsp rad, 7thN

This code describes a radius fracture where the bone has healed in a bent or angulated position, rather than straight. It specifically applies to open fractures (where the bone broke through the skin) classified as Type IIIA, IIIB, or IIIC, and indicates that the fracture has failed to heal completely (nonunion) during a subsequent phase of treatment.

Use this code for a patient presenting for follow-up care of a previously treated open radius fracture (Type IIIA, IIIB, or IIIC) that has resulted in a malunion (bent bone) and has not yet fully united. This would be appropriate when the nonunion is still an active problem being addressed.

• Always sequence this code after the appropriate external cause code, if applicable.
• Ensure documentation clearly specifies "bent bone" or "malunion" of the radius and confirms an open fracture type IIIA, IIIB, or IIIC with nonunion.
• Verify that the encounter is for subsequent care related to the nonunion and malunion, not the initial treatment.
