Pathological fracture, right radius, subs for fx w nonunion

This code signifies a fracture of the right radius that occurred due to an underlying disease process, rather than trauma. The fracture has failed to heal properly, resulting in a nonunion, and the patient is currently receiving routine care during the healing phase.

Apply this code when a patient presents for follow-up care, cast changes, or medication management for a right radial pathological fracture that has been diagnosed with nonunion. Documentation should clearly state "pathological fracture," "right radius," "nonunion," and indicate that this is a "subsequent encounter" for the fracture.

• Always sequence this code after the underlying disease causing the pathological fracture (e.g., osteoporosis, neoplasm).
• Distinguish from initial encounters (A/D) and sequela (S) codes; this "K" suffix is specifically for subsequent encounters with nonunion.
• Ensure documentation explicitly states "nonunion" and not just "delayed healing" or "malunion," as these require different codes.
