Pathological fracture, right tibia, subs for fx w nonunion

This code signifies a pathological fracture of the right tibia that has failed to heal properly, resulting in a nonunion. A pathological fracture occurs due to a weakened bone structure, often from an underlying disease process rather than trauma. The "subsequent encounter" indicates the patient is receiving routine care during the healing or recovery phase for this nonunion.

Use this code for patients presenting for follow-up care, cast changes, medication management, or other ongoing treatment related to a right tibial pathological fracture that has been diagnosed with nonunion. Documentation should clearly state "pathological fracture," specify the right tibia, and confirm the presence of a nonunion during a subsequent encounter. This code is appropriate when the patient is no longer in the initial acute phase of treatment.

• Always ensure documentation specifies "pathological" fracture and not a traumatic fracture.
• Verify laterality (right tibia) and the "nonunion" status are explicitly stated.
• Remember to also code the underlying condition causing the pathological fracture (e.g., osteoporosis, neoplasm).
