Oth traum nondisp spondylolysis of second cervcal vert, sqla

This code signifies a chronic or late effect of a traumatic, nondisplaced forward slippage of the second cervical vertebra (C2) on the third cervical vertebra (C3). It indicates that the initial injury has resolved, but the patient is experiencing ongoing symptoms or complications directly attributable to that past spondylolisthesis.

Apply this code when documentation clearly indicates a sequela (late effect) of a previously sustained traumatic, nondisplaced spondylolisthesis of C2. This typically involves chronic pain, neurological deficits, or functional limitations directly resulting from the old injury. Supporting documentation should specify the traumatic origin and the nondisplaced nature of the original C2 spondylolisthesis.

• Ensure "sequela" or "late effect" is explicitly documented, indicating the current condition is a residual of a past injury.
• Verify the specific vertebral level (C2) and the nondisplaced nature of the spondylolisthesis.
• Do not use for acute injuries; instead, refer to the acute traumatic spondylolisthesis codes.
