Oth traum nondisp spondylolysis of 7th cervcal vert, sqla

This code describes a long-term complication or late effect resulting from a past traumatic injury that caused a nondisplaced forward slippage of the seventh cervical vertebra (C7) over the vertebra below it. The spondylolisthesis itself is not acute, but rather a persistent issue or consequence of the original trauma.

Use this code when documenting a patient presenting with symptoms or conditions directly attributable to a previously sustained, traumatic, nondisplaced spondylolisthesis at C7. Documentation should clearly indicate that the spondylolisthesis is a sequela (a late effect) of an old injury, not an acute event. This code is appropriate for follow-up care related to the chronic effects of such an injury.

• Always sequence this sequela code after the code(s) for the specific condition(s) or symptoms being treated that are due to the spondylolisthesis.
• Ensure documentation specifies "nondisplaced" and "seventh cervical vertebra" to differentiate from other types or locations of spondylolisthesis.
• Distinguish from acute traumatic spondylolisthesis codes (S12.6xxA) or pathological spondylolisthesis (M43.1x) which would not use the "S" seventh character.
