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

This code describes a fracture of the odontoid process (dens) of the C2 vertebra that is not displaced, specifically a Type II fracture according to the Anderson and D'Alonzo classification. The patient is in a subsequent phase of care, and the fracture is healing as expected without complications.

Apply this code for follow-up encounters where a patient with a previously diagnosed nondisplaced Type II dens fracture is being monitored for routine healing. Documentation should confirm the fracture type, lack of displacement, and indicate that the healing process is progressing normally, typically noted in progress notes or follow-up imaging reports.

• Ensure documentation specifies "Type II" dens fracture and "nondisplaced."
• The "D" seventh character indicates a subsequent encounter for routine healing; do not use for initial treatment or delayed/nonunion.
• Always confirm the specific type and displacement of the dens fracture, as other types (e.g., Type I, Type III, displaced) have different codes.
