Ant displ Type II dens fracture, subs for fx w delay heal

This code signifies a fracture of the odontoid process (dens) of the C2 vertebra, specifically a Type II fracture where the anterior portion is displaced. The "G" seventh character indicates that the patient is receiving active treatment for the fracture during a subsequent encounter, but the healing process is slower than expected.

Apply this code when a patient presents for follow-up care of a previously diagnosed anteriorly displaced Type II dens fracture, and the physician's documentation explicitly states or implies delayed healing. This typically involves ongoing management such as bracing, physical therapy, or monitoring for nonunion, after the initial acute treatment phase.

• Ensure documentation clearly specifies "delayed healing" or a similar term to justify the "G" seventh character.
• Distinguish from nonunion (S12.110K) or routine healing (S12.110D) in subsequent encounters.
• Always sequence this code as the primary diagnosis when the delayed healing of the fracture is the reason for the encounter.
