Barton's fx r radius, subs for opn fx type I/2 w nonunion

This code signifies a specific type of distal radius fracture, known as a Barton's fracture, affecting the right arm. It indicates that the fracture is an open type I or II, meaning there is a wound communicating with the fracture site, and that the bone fragments have failed to heal together after an initial treatment.

This code is appropriate for follow-up encounters where a patient with a previously treated open type I or II Barton's fracture of the right radius is presenting with evidence of nonunion. This includes situations where surgical intervention for nonunion is being planned or performed, or during ongoing management of the unhealed fracture.

• Ensure documentation clearly specifies "Barton's fracture" and "right radius" to support this code.
• Verify the open fracture type (I or II) and the presence of nonunion are explicitly stated in the medical record.
• This code is for subsequent encounters; an initial encounter for the same fracture with nonunion would use a different seventh character.
