Unsp fx navicular bone of r wrist, subs for fx w nonunion

This code signifies a fracture of the scaphoid bone in the right wrist where the specific type of fracture (e.g., displaced, nondisplaced) is not documented. The key aspect is that the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Use this code for a patient with a previously diagnosed right scaphoid fracture that has not united, and the medical record does not specify the fracture type. This applies to subsequent visits for management of the nonunion, such as evaluation for surgical intervention, cast changes, or monitoring healing progress.

• Ensure documentation clearly states "nonunion" and specifies the right wrist scaphoid.
• Only use this code when the specific fracture type (e.g., displaced, nondisplaced) is not documented.
• This code is for subsequent encounters; an initial encounter for the nonunion would use a different seventh character.
