Question: Would you direct us to the appropriate ICD-9 code for anterolisthesis?

Answer: Anterolisthesis is another name for spondylolisthesis. This condition causes one vertebra to slide down onto the vertebra below it. If the condition is congenital, use 756.12 (Spondylolisthesis) as your diagnosis code; if the condition is degenerative or acquired, report 738.4 (Acquired spondylolisthesis).
