Oth disp fx of fourth cervical vertebra, init for opn fx

This code signifies a fracture of the fourth cervical vertebra that is not in its normal anatomical alignment and involves an open wound communicating with the fracture site. This injury typically results from significant trauma to the neck, compromising the integrity of the spinal column at C4.

Apply this code for a patient presenting with an acute, displaced fracture of the C4 vertebra where there is an open wound (e.g., laceration, puncture) extending to the fracture site. Documentation should clearly state "displaced," "open fracture," and specify the "fourth cervical vertebra" as the affected level, and that this is the initial treatment encounter.

• Ensure documentation explicitly states "displaced" and "open" for accurate code assignment.
• Verify the specific cervical vertebral level (C4) is documented to differentiate from other cervical fractures.
• The "B" seventh character indicates an initial encounter for an open fracture; use appropriate subsequent characters for follow-up care.
