Dislocation of C4/C5 cervical vertebrae, sequela

This code signifies a long-term or late-effect condition resulting from a previous dislocation of the cervical vertebrae between C4 and C5. It indicates that the patient is experiencing ongoing issues directly attributable to that past injury, rather than an acute or initial event. These sequelae can include chronic pain, neurological deficits, or instability.

Apply this code when documenting a patient's current condition that is a direct consequence of a resolved C4/C5 cervical dislocation. This is appropriate for follow-up visits where the original injury has healed but its lasting impact is being treated. It should not be used for the initial or acute treatment of the dislocation itself.

• Always sequence this code after the code describing the specific manifestation of the sequela (e.g., chronic pain, myelopathy).
• Ensure documentation clearly links the current condition to the prior C4/C5 dislocation.
• Do not use for initial injury or subsequent acute dislocations; those require acute injury codes.
