Path fx in oth disease, r femur, subs for fx w nonunion

This code signifies a right femur fracture that occurred due to an underlying disease process, not trauma, and has failed to heal properly. The "nonunion" indicates that the bone fragments have not united after a reasonable healing period, and the "subsequent encounter" specifies that this is not the initial treatment for the fracture.

Use this code for follow-up visits where a patient is being managed for a right femoral pathological fracture that has developed nonunion. Documentation should clearly state the fracture's pathological origin, its location (right femur), and the ongoing nonunion status, often confirmed by imaging.

• Ensure documentation specifies "pathological" fracture and the underlying disease causing it (code the underlying disease first).
• Distinguish between "nonunion" and "malunion"; this code is specific to nonunion.
• Verify the encounter type; "K" indicates a subsequent encounter for a fracture with nonunion.
