Unsp traum displ spondylolysis of third cervcal vert, sqla

This code signifies a long-term complication or late effect resulting from a traumatic injury that caused the third cervical vertebra (C3) to slip forward over the vertebra below it, without specifying the exact type of spondylolisthesis. The "sequela" designation indicates that this is a residual condition occurring after the acute phase of the original injury has passed.

Apply this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a past traumatic displaced spondylolisthesis of C3. Documentation should clearly state the traumatic origin of the spondylolisthesis and that the current condition is a sequela, rather than an acute injury. This code is appropriate when the specific type of spondylolisthesis (e.g., fracture, pars interarticularis defect) is not documented.

• Always sequence the sequela code first, followed by codes for any associated manifestations or complications.
• Ensure documentation explicitly links the current condition to a past traumatic event involving C3 spondylolisthesis.
• Avoid using this code for acute injuries; instead, use the appropriate acute traumatic spondylolisthesis code.
