Oth traum displ spondylolysis of fifth cervcal vert, sequela

This code signifies a chronic or late-effect condition resulting from a traumatic injury that caused a forward slippage of the fifth cervical vertebra (C5) over the vertebra below it. This displacement is not due to a congenital defect or degenerative process, but specifically from a past trauma. The "sequela" designation indicates that the initial injury has healed, but the patient continues to experience residual effects directly attributable to the spondylolisthesis.

This code is appropriate for encounters addressing long-term complications or persistent symptoms directly related to a previously sustained traumatic displaced spondylolisthesis of C5. This includes follow-up care for chronic pain, neurological deficits, or functional limitations stemming from the old injury. It should be used when the acute phase of the injury has passed and the current treatment is for the lasting consequences.

• Always use this code as a secondary diagnosis, following a primary code for the specific sequela being treated (e.g., chronic pain, radiculopathy).
• Ensure documentation clearly links the current condition to a past traumatic event involving C5 spondylolisthesis.
• Do not use for acute traumatic spondylolisthesis; refer to the acute injury codes for initial encounters.
