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

This code signifies a fracture of the lower portion of the left ulna, excluding common types like styloid or epiphyseal, that was initially an open fracture (Type I or II). The patient is currently in a phase of routine healing following the initial treatment of the open fracture.

This code is appropriate for follow-up encounters where a patient is recovering from an open fracture of the distal left ulna, and the healing process is progressing as expected without complications. It should be used when the fracture type is not specifically identified as styloid, epiphyseal, or other specified types.

• Ensure the encounter is for subsequent care, not the initial treatment.
• Verify the fracture was originally classified as an open fracture, Type I or II.
• Confirm the healing is routine; use different codes for delayed healing or nonunion.
