Unsp fracture of right forearm, subs for clos fx w nonunion

This code signifies a fracture of the right forearm where the specific bone (radius or ulna) and type of fracture are not documented, and the fracture has failed to heal properly after an initial treatment. The fracture site remains closed, meaning there is no open wound communicating with the fracture.

This code is appropriate for follow-up encounters for a right forearm fracture that was initially treated conservatively or surgically, but imaging or clinical assessment now indicates nonunion. It applies when the documentation does not specify whether the radius or ulna is fractured, or the exact fracture pattern.

• Ensure documentation explicitly states "nonunion" and that the fracture is closed.
• Verify laterality (right forearm) and that the fracture type is unspecified.
• Do not use if the specific bone (radius or ulna) or fracture type is known; a more specific code should be selected.
