Oth fx low end r tibia, subs for opn fx type I/2 w malunion

This code signifies a healed or healing fracture of the lower end of the right tibia that initially presented as an open fracture (Type I or II) but has subsequently healed in an imperfect alignment (malunion). The patient is currently receiving follow-up care for this specific complication.

This code is appropriate for documenting ongoing treatment or evaluation of a patient whose right distal tibia fracture, originally open, has united with a noticeable deformity or angulation. It is used when the malunion is the primary focus of the current encounter, rather than the initial acute injury.

• Ensure the documentation clearly specifies "malunion" and that the initial fracture was an open Type I or II.
• This code is for subsequent encounters, not the initial treatment of the fracture.
• Verify laterality (right tibia) and the specific anatomical location (lower end/distal).
