Nondisp fx of neck of MC bone, subs for fx w delay heal

This code signifies a fracture of the neck of a metacarpal bone, excluding the thumb, that is not displaced. The patient is in a later stage of care, and the fracture is not healing at the expected rate. This indicates ongoing medical management for a persistent fracture.

Apply this code when a patient presents for follow-up care of a metacarpal neck fracture (other than the first metacarpal) that was previously diagnosed and is now demonstrating delayed union. This would be used for subsequent visits where the physician documents that the fracture is not healing as anticipated.

• Ensure documentation explicitly states "delayed healing" or "delayed union" for the metacarpal neck fracture.
• Verify that the fracture is of a metacarpal other than the thumb (i.e., second, third, fourth, or fifth metacarpal).
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
