Unsp fx shaft of right ulna, subs for clos fx w delay heal

This code indicates a fracture of the shaft of the right ulna where the specific type of fracture (e.g., transverse, oblique) is not documented. It signifies that the patient is in a later stage of care for a previously diagnosed closed fracture, and the healing process is taking longer than expected.

Use this code for follow-up encounters when a patient with a right ulnar shaft fracture, initially treated as closed, is experiencing delayed union. This applies when the physician notes that the fracture is not healing at the anticipated rate, but there is no evidence of nonunion or malunion yet.

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