Unsp fx r low leg, subs for opn fx type 3A/B/C w nonunion

This code signifies a non-healing fracture of the lower leg on the right side, specifically an open fracture of severe type (IIIA, IIIB, or IIIC). It indicates that the patient is receiving ongoing care for this complex fracture which has failed to unite.

Apply this code for follow-up encounters when a patient presents with a previously diagnosed open fracture of the right lower leg (types IIIA, IIIB, or IIIC) that has progressed to nonunion. This is appropriate for visits related to continued management, such as wound care, bone grafting procedures, or assessment for further surgical intervention due to the nonunion.

• Ensure documentation clearly specifies the right lower leg and the open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is for ongoing treatment of the nonunion, not the initial injury or routine healing.
• Always sequence this code after any codes for complications or specific treatments performed during the encounter.
