Oth displaced dens fracture, subs for fx w delay heal

This code signifies a fracture of the dens (odontoid process) of the C2 vertebra that is displaced, meaning the bone fragments are not properly aligned. The "G" suffix indicates that this is a subsequent encounter for the fracture, and the patient is experiencing delayed healing.

Apply this code when a patient presents for follow-up care of a previously diagnosed, displaced dens fracture, and the physician's documentation explicitly states or implies that the healing process is not progressing as expected or is taking longer than anticipated. Documentation should include imaging reports confirming the fracture and displacement, along with clinical notes detailing the delayed healing.

• Ensure documentation clearly specifies "displaced" and "delayed healing" for the dens fracture.
• Distinguish from nonunion (S12.120K) or malunion (S12.120P), which represent different healing complications.
• Always sequence this code after any acute injury codes if the patient is still within the initial treatment phase for other injuries.
