Unsp nondisp fx of 4th cervcal vert, 7thG

This code signifies a fracture of the fourth cervical vertebra that was initially nondisplaced and whose specific type is not documented. The patient is currently in a phase of treatment where the fracture is healing slower than expected, requiring continued medical management.

Apply this code when a patient presents for follow-up care of a previously diagnosed, nondisplaced C4 vertebral fracture that is exhibiting delayed healing. Documentation should clearly state "delayed healing" or similar terminology, and indicate that the fracture is of the fourth cervical vertebra without further specification of the fracture type.

• Ensure documentation explicitly states "delayed healing" for the subsequent encounter.
• Verify the fracture is specifically of the fourth cervical vertebra (C4) and not another cervical level.
• This code requires an external cause code (e.g., V00-Y99) to describe the circumstances of the injury.
