Unspecified disp fx of fourth cervical vertebra, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained, unspecified displaced fracture of the fourth cervical vertebra. It indicates that the initial injury has healed, but the patient continues to experience residual problems directly attributable to that fracture. This could include chronic pain, neurological deficits, or functional limitations.

This code is appropriate when documenting a patient's current condition that is a direct consequence of a past, unspecified displaced fracture of the C4 vertebra. The medical record should clearly state the link between the current symptoms and the historical fracture, and indicate that the acute phase of the fracture has passed. Documentation must specify that the fracture was displaced and involved the fourth cervical vertebra.

• Always use this "S" seventh character for sequela when the patient is seen for a late effect of the fracture, not for the initial healing or acute treatment.
• Do not use this code for current, active fractures; instead, select an appropriate acute fracture code.
• Ensure documentation explicitly states the sequela of the fracture, rather than just mentioning a history of fracture.
