Question: What code applies to an intrathecal catheter dye study under fluoroscopy? Answer: The answer depends partly on whether you're coding for the dye study alone or for the catheter insertion as well. It appears that you're only coding for the dye study. If that's the case, report 75809 (Shuntogram for investigation of previously placed indwelling nonvascular shunt [e.g., LeVeen shunt, ventriculoperitoneal shunt, indwelling infusion pump], radiological supervision and interpretation).
