Unsp traum displ spondylolysis of fourth cervcal vert, sqla

This code describes a long-term complication or late effect resulting from an unspecific traumatic displaced spondylolisthesis of the C4 vertebra. It indicates that the initial injury has healed, but residual issues related to the vertebral displacement persist. The "unspecified" nature means the specific type of spondylolisthesis (e.g., isthmic, degenerative) is not documented.

Use this code when a patient presents for treatment of a chronic condition or complication directly attributable to a past traumatic C4 spondylolisthesis, where the initial injury has resolved. Documentation should clearly link the current symptoms or condition to the previous traumatic C4 spondylolisthesis and indicate that the displacement was not reduced or has recurred. This code is appropriate for follow-up care related to the long-term effects.

• Requires a seventh character "S" to indicate sequela, meaning the current condition is a late effect of the original injury.
• Do not use for initial encounters or subsequent encounters for active treatment of the acute injury.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, neurological deficit).
