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

This code signifies a fracture of the lower portion of the right ulna, where the specific type of fracture (e.g., transverse, oblique) 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.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed closed fracture of the distal right ulna is experiencing delayed healing. It would be used when the physician notes that the fracture has not fully united within the anticipated timeframe, but there are no complications like infection or malunion yet.

• Ensure documentation specifies "delayed healing" for a closed fracture.
• Verify the encounter is subsequent to the initial treatment of the fracture.
• Do not use if the fracture is open, or if nonunion or malunion is explicitly documented.
