Unsp nondisp fx of fourth cervical vertebra, init

This code signifies a fracture of the fourth cervical vertebra that is not displaced and the specific type of fracture is unknown. It indicates the initial treatment phase for a closed fracture, meaning the skin remains intact over the injury site.

Apply this code for a patient presenting with a newly diagnosed, non-displaced C4 vertebral fracture where the specific fracture morphology (e.g., comminuted, wedge) is not documented. This is appropriate when the fracture is closed and the patient is receiving initial active treatment.

• Ensure documentation explicitly states "nondisplaced" and "closed fracture" for initial encounter.
• Avoid using this code if the fracture type (e.g., compression, burst) is specified; instead, use a more specific code from the S12.3- series.
• Do not use for subsequent encounters or for open fractures; different codes apply for those scenarios.
