Barton's fracture of r radius, subs for clos fx w malunion

This code signifies a specific type of distal radius fracture, a Barton's fracture, affecting the right arm. It indicates that the fracture has previously been treated, but healing has occurred in an unsatisfactory alignment, known as a malunion, and the skin over the fracture site remains intact.

Use this code for follow-up encounters where a patient with a previously diagnosed and treated right Barton's fracture presents with complications related to malunion. This applies when the fracture is no longer acute but is still undergoing treatment or evaluation for the malunion, and the skin is not broken.

• Ensure documentation clearly specifies "Barton's fracture" and "right radius."
• Verify the encounter is for a "subsequent encounter" and that "malunion" is documented.
• Confirm the fracture is "closed" (no open wound communicating with the fracture site).
