Nondisp post arch fx 1st cervcal vert, 7thD

This code signifies a fracture of the posterior arch of the C1 vertebra (atlas) that has not shifted from its anatomical position. The patient is in a follow-up phase of care, and the fracture is healing as expected without complications. This typically indicates ongoing conservative management or post-surgical follow-up for a stable injury.

Apply this code for follow-up visits where a patient with a previously diagnosed nondisplaced posterior arch C1 fracture is demonstrating routine healing. Documentation should explicitly state "subsequent encounter" and confirm the fracture's nondisplaced nature and routine healing progress. This code is appropriate when the patient is no longer in the initial acute phase of treatment.

• Ensure documentation specifies "nondisplaced" and "posterior arch" of the first cervical vertebra.
• Verify the encounter type is "subsequent" and healing is described as "routine" or "normal."
• Do not use for initial encounters or for fractures with delayed healing, nonunion, or malunion.
