Oth 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, excluding specific types like Salter-Harris or physeal fractures, that is currently in a phase of delayed healing. The fracture was initially closed, meaning the skin remained intact over the injury site.

This code is appropriate for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed closed fracture of the distal right ulna that is not healing at the expected rate. This includes situations where the patient is undergoing conservative management or awaiting further intervention due to delayed union.

• Ensure documentation clearly specifies "delayed healing" for a closed fracture.
• Verify the fracture location is the "lower end" or "distal" ulna, and laterality is "right."
• Do not use for initial encounters or for fractures that are healing normally.
