Oth intartic fx lower end r rad, subs for clos fx w nonunion

This code describes a fracture within the joint space at the lower end of the right radius that is not healing properly, and the patient is presenting for follow-up care. The fracture itself is closed, meaning the skin is intact over the injury site. "Nonunion" indicates that the bone fragments have failed to unite after a sufficient healing period.

Use this code when a patient with a previously diagnosed intraarticular fracture of the distal right radius, which was initially closed, returns for an appointment where nonunion of the fracture is documented. This applies to follow-up visits for ongoing management, assessment of healing progress, or planning for further intervention due to the nonunion.

• Ensure documentation clearly specifies "nonunion" of the fracture, not just delayed healing.
• Verify the fracture is intraarticular and located at the lower end of the right radius.
• Confirm this is a subsequent encounter for a closed fracture; initial encounters or open fractures would use different codes.
