Oth traum nondisp spondylolysis of third cervcal vert, sqla

This code signifies a chronic or late effect of a traumatic injury resulting in a nondisplaced forward slippage of the third cervical vertebra (C3) over the fourth (C4). "Nondisplaced" indicates the vertebral body has not shifted significantly out of alignment, and "spondylolisthesis" refers specifically to the vertebral slippage. "Sequela" denotes that this is a residual condition occurring after the acute phase of the original injury has passed.

This code is appropriate when documenting a long-term consequence of a past traumatic event that caused a C3 spondylolisthesis, where the displacement is minimal. It should be used when the patient presents for evaluation or treatment of symptoms directly attributable to this chronic condition, such as persistent neck pain, radiculopathy, or neurological deficits. Documentation must clearly state the traumatic origin, the specific vertebra involved (C3), the nondisplaced nature, and the sequela status.

• Ensure documentation explicitly links the spondylolisthesis to a past traumatic event and confirms its "nondisplaced" status.
• The "S" seventh character indicates sequela; do not use for initial or subsequent encounters for the acute injury.
• Always sequence this code after the primary diagnosis for the current encounter if the sequela is not the primary reason for the visit.
