Oth fx shaft of rad, r arm, 7thN

This code describes a complex fracture of the right radial shaft, specifically an open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly after initial treatment. The "subsequent encounter" indicates that the patient is receiving ongoing care for this nonunion, not the initial injury.

Apply this code for follow-up visits where a patient is being managed for a previously diagnosed open fracture of the right radial shaft that has progressed to nonunion. This includes scenarios such as surgical intervention for nonunion, cast changes, or evaluation of healing progress in the context of nonunion.

• Ensure documentation clearly specifies "right arm" and "shaft of radius."
• Verify the encounter is for a subsequent visit related to the nonunion, not the initial fracture treatment.
• Confirm the original fracture was classified as an open fracture type IIIA, IIIB, or IIIC.
