Unsp traum displ spondylolysis of seventh cervcal vert, sqla

This code signifies a long-term complication or late effect stemming from an unspecified traumatic displaced forward slippage of the seventh cervical vertebra. This condition indicates a prior injury to the C7 vertebra that resulted in its displacement, and the current encounter addresses a residual problem related to that initial trauma.

Apply this code when documentation clearly indicates a sequela (late effect) of a past traumatic spondylolisthesis of the C7 vertebra, where the specific type of displacement is not documented. This code is appropriate for follow-up care, chronic pain, or other persistent issues directly attributable to the original injury.

• Always sequence this code after the primary diagnosis describing the nature of the sequela.
• Ensure documentation specifies "sequela" or "late effect" and links the current condition to a past traumatic C7 spondylolisthesis.
• Do not use for acute or initial traumatic spondylolisthesis; those require acute injury codes.
