Unsp fx upper end of r ulna, subs for clos fx w delay heal

This code signifies a fracture of the upper portion of the right ulna, where the specific type of fracture is not documented. It indicates that the patient is in a later stage of healing for a closed fracture, but the bone union is progressing slower than expected.

Apply this code when a patient presents for follow-up care of a previously diagnosed, non-displaced or minimally displaced right ulnar fracture (proximal end) that was initially closed, and the physician notes delayed healing. This is appropriate for subsequent visits after the initial treatment, but before definitive healing is achieved.

• Ensure documentation specifies "right ulna" and "upper end" (proximal).
• Verify the encounter is for follow-up care of a closed fracture with explicit mention of delayed healing.
• Do not use for initial encounters or for fractures that are healing normally.
