Pathological fracture, left hand, subs for fx w nonunion

This code signifies a fracture of the left hand that occurred due to a weakened bone (pathological fracture) and has failed to heal properly. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase of this nonunion.

Use this code for follow-up visits where a patient is being treated for a left hand pathological fracture that has been diagnosed with nonunion. Documentation should clearly state the pathological nature of the fracture, its location in the left hand, and the ongoing management of the nonunion.

• Ensure documentation specifies "pathological fracture" and not just a simple fracture.
• Verify the laterality (left hand) is clearly documented.
• Confirm the encounter type is for ongoing treatment of the nonunion, not initial care or sequelae.
