Barton's fx unsp radius, subs for clos fx w nonunion

This code describes a specific type of distal radius fracture, known as a Barton's fracture, which involves the articular surface of the radius. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" signifies that the bone fragments have failed to heal together after a typical healing period. The "unspecified radius" means the laterality (left or right) of the fracture is not documented.

This code is appropriate for documenting ongoing treatment for a Barton's fracture where the bone has not successfully united. This would include scenarios such as surgical intervention for nonunion, casting or bracing for persistent nonunion, or evaluation of the nonunion status during a follow-up visit. It is used after the initial treatment of the fracture.

• Ensure documentation clearly states "nonunion" and that the encounter is not for initial treatment.
• Verify that the fracture is specifically identified as a Barton's fracture.
• If laterality (left or right radius) is documented, a more specific code should be selected.
