Unspecified nondisp fx of fifth cervical vertebra, sequela

This code indicates a long-term complication or late effect stemming from a previously sustained, unspecified, nondisplaced fracture of the fifth cervical vertebra. The original injury has healed, but the patient is experiencing residual symptoms or conditions directly attributable to that past fracture.

Apply this code when documentation clearly links a current condition or symptom to a prior, healed, nondisplaced C5 vertebral fracture. This is appropriate for follow-up encounters addressing chronic pain, neurological deficits, or functional limitations that are direct sequelae of the old injury. Supporting documentation must specify the nature of the sequela and its causal relationship to the past fracture.

• Always sequence the code for the specific sequela (e.g., chronic pain, myelopathy) before this sequela code.
• Ensure documentation explicitly states the fracture was "nondisplaced" and identifies the "fifth cervical vertebra."
• Do not use for acute or subacute fractures; this code is strictly for late effects/sequelae.
