Oth fx upper end r rad, subs for opn fx type I/2 w nonunion

This code signifies a nonunion of an open fracture (Gustilo type I or II) involving the upper end of the right radius, specifically an "other" type of fracture beyond the more common neck or head fractures. Nonunion indicates that the fracture has failed to heal completely within the expected timeframe. This is a subsequent encounter code, meaning the patient is returning for ongoing management of this specific complication.

Use this code for patients presenting for follow-up care, evaluation, or treatment of a previously sustained open fracture of the proximal right radius that has not healed and is now classified as a nonunion. This applies when the initial fracture was an open type I or II. It is appropriate when the focus of the encounter is on managing the nonunion rather than the initial acute injury.

• Ensure documentation clearly specifies "nonunion" and the "open" nature (type I or II) of the original fracture.
• Verify the fracture location is the "upper end of radius" and not specifically the head or neck, which have their own codes.
• Confirm this is a subsequent encounter for the nonunion, not an initial treatment or a sequela of a healed fracture.
