Oth fx low end r ulna, subs for opn fx type I/2 w routn heal

This code signifies a fracture of the lower portion of the right ulna, excluding specific types like Salter-Harris or Torus fractures, that has broken through the skin (open fracture type I or II). The patient is in a subsequent phase of care, and the fracture is healing as expected without complications.

This code is appropriate for follow-up encounters where a patient is receiving ongoing treatment for an open fracture of the distal right ulna, and the healing process is progressing routinely. This would include situations where the patient is undergoing cast changes, wound care, or physical therapy during the healing phase. It is used after the initial treatment of the acute injury.

• Ensure documentation specifies "right" ulna and "lower end" or "distal" ulna.
• Verify the encounter is for a subsequent visit and not the initial treatment.
• Confirm the open fracture type (I or II) and that healing is described as "routine" or "expected."
