Unsp disp fx of fifth cervcal vert, subs for fx w routn heal

This code signifies a follow-up encounter for a fracture of the fifth cervical vertebra (C5) that was initially displaced but is now healing routinely. The specific type of C5 fracture is not documented. This code indicates the patient is progressing as expected in the healing process following the initial injury.

Use this code for subsequent encounters when a patient with a previously diagnosed, unspecified, displaced C5 fracture is undergoing routine follow-up care and the fracture is demonstrating expected healing. Documentation should clearly state "subsequent encounter," "routine healing," and specify the fifth cervical vertebra.

• Ensure documentation specifies "unspecified" fracture type and "displaced" status from the initial encounter.
• Confirm the encounter is for routine healing; do not use for delayed healing, nonunion, or malunion.
• Always sequence this code after the initial fracture code (S12.400A) if the initial encounter is also being coded.
