Unsp disp fx of 4th cervcal vert, subs for fx w routn heal

This code signifies a fracture of the fourth cervical vertebra that has not been specified as to its exact type, but is known to be displaced. The patient is in the healing phase, and the fracture is progressing routinely without complications.

This code is appropriate for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed, unspecified displaced C4 fracture that is healing normally. Documentation should clearly indicate "subsequent encounter" and confirm routine healing, often noted as "healing well" or "stable."

• Ensure documentation specifies "displaced" and "unspecified" fracture type for C4.
• Verify the encounter is for follow-up care during the healing phase, not initial treatment or a nonunion.
• Do not use if the fracture is explicitly described as nondisplaced, comminuted, or other specific types.
