Nondisplaced Type II dens fracture, subs for fx w delay heal

This code describes a fracture of the odontoid process (dens) of the C2 vertebra that is classified as Type II according to the Anderson and D'Alonzo classification, meaning it occurs at the base of the dens. "Nondisplaced" indicates the bone fragments are in their anatomical position. "Subsequent encounter for fracture with delayed healing" signifies that the patient is receiving follow-up care for this fracture, and the healing process is taking longer than expected.

This code is used when a patient with a previously diagnosed nondisplaced Type II dens fracture presents for ongoing treatment, and the physician documents that the fracture is experiencing delayed healing. Documentation should clearly state "Type II dens fracture," "nondisplaced," and explicitly mention "delayed healing" or similar terminology indicating a prolonged healing process. This code is appropriate for office visits, hospital outpatient visits, or inpatient stays focused on managing the delayed healing.

• Ensure documentation specifies "Type II" dens fracture and "nondisplaced" to differentiate from other types or displaced fractures.
• The "G" seventh character indicates subsequent encounter with delayed healing; do not use for initial treatment or routine healing.
• Always sequence this code as the primary diagnosis when the delayed healing of the fracture is the reason for the encounter.
