Displ lateral mass fx 1st cervcal vert, 7thD

This code signifies a fracture of the lateral mass of the C1 vertebra that is no longer in its anatomical position. The "D" in the seventh character indicates that the patient is in the healing phase of the fracture and is receiving routine follow-up care.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed displaced lateral mass fracture of the atlas (C1) is undergoing routine healing. Documentation should clearly state the fracture is displaced, located in the lateral mass of C1, and that the current encounter is for routine follow-up during the healing process.

• Ensure documentation specifies "displaced" and "lateral mass" of C1.
• The seventh character "D" is crucial for subsequent encounters with routine healing; do not use "A" (initial) or "G" (delayed healing).
• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
