Fx unsp phalanx of l rng fngr, subs for fx w malunion

This code signifies a fracture of an unspecified phalanx in the left ring finger that has healed improperly, resulting in malunion. This means the bone fragments have joined together in an anatomically incorrect position, potentially leading to functional impairment or deformity. The "subsequent encounter" indicates that the patient is receiving ongoing care for this previously diagnosed and treated fracture.

Use this code when a patient presents for follow-up care, evaluation, or treatment of a malunited fracture of the left ring finger's phalanx. This would include scenarios where the malunion is being assessed for surgical correction, physical therapy, or other interventions to address the improper healing. It is appropriate for any encounter after the initial treatment of the fracture where malunion is the primary focus.

• Ensure documentation clearly specifies "malunion" and the "left ring finger" for accurate code assignment.
• Verify that this is a subsequent encounter, not the initial treatment of the fracture or a nonunion.
• Always review the medical record for laterality and specific finger/phalanx involvement to avoid unspecified codes.
