Disp fx of middle phalanx of unspecified finger, 7thK

This code signifies a fracture of the middle bone of an unknown finger that has shifted out of alignment. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together properly.

Apply this code when a patient presents for ongoing treatment of a previously diagnosed displaced middle phalanx fracture of an unspecified finger, and the medical record clearly documents that the fracture has not united. This would include scenarios such as surgical intervention for nonunion, cast changes, or evaluation of healing progress where nonunion is confirmed.

• Ensure documentation specifies "nonunion" and not just "delayed healing" for accurate code assignment.
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm that the specific finger is not documented, as more specific codes exist for known fingers.
