Unsp traum nondisp spondylolysis of fifth cervcal vert, sqla

This code describes a long-term complication or late effect resulting from an injury that caused an unspecified traumatic nondisplaced spondylolisthesis of the fifth cervical vertebra. It indicates that the vertebral body has slipped forward relative to the vertebra below it, but without displacement, and the original injury occurred in the past.

This code is appropriate when a patient presents for treatment of a current problem directly attributable to a past traumatic nondisplaced spondylolisthesis of C5. Documentation should clearly state that the spondylolisthesis is a sequela (late effect) of a previous injury and specify the fifth cervical vertebra.

• Always assign an external cause code (e.g., V00-Y99) to describe the original injury that led to the sequela, if known.
• Do not use this code for acute or initial encounters for the injury; use an acute S12.431A code instead.
• Ensure documentation explicitly states "sequela" or "late effect" and specifies the C5 level and nondisplaced nature.
