Nondisp fx of nk of unsp rad, subs for clos fx w delay heal

This code signifies a fracture of the radial neck that is not displaced, meaning the bone fragments remain in their anatomical position. The encounter is for follow-up care of this closed fracture, and the healing process is progressing slower than expected.

Apply this code for patients presenting for subsequent treatment of a previously diagnosed, non-displaced radial neck fracture where the skin remains intact over the fracture site, and the physician documents delayed union or delayed healing. This is used when the patient is still receiving active treatment for the fracture.

• Ensure documentation explicitly states "nondisplaced" and "delayed healing" for the radial neck.
• Verify that the encounter is for follow-up care, not the initial treatment.
• Confirm the fracture is closed; open fractures have different coding pathways.
