Answer: Tarlov cyst is just another term for perineural cyst, which you’d report with G96.191 (Perineural cyst).

Also: In addition to a Tarlov cyst, report G96.191 if you see these conditions listed on encounter notes:

  • Cervical nerve root cyst
  • Lumbar nerve root cyst
  • Sacral nerve root cyst
  • Thoracic nerve root cyst.
