Coding for a radionucleotide cisternogram with subsequent head and facial imaging


Do you have any information regarding CPT® coding for a CT cisternogram? The patient is scheduled for a CT head and facial exam without contrast, then the patient goes to radiology for a lumbar puncture with an injection of contrast. Once the contrast is injected, the patient returns to CT for head and facial imaging with contrast. This is a relatively new procedure for our department, so we want to make sure we are coding and building it into our system properly.


You would report the lumbar contrast administration code, 62284 with the appropriate CT codes (in your example, 70470 and 70488). Whether or not the insurance will reimburse would depend on their policy. If fluoroscopic guidance is used for the injection, you can also assign CPT code 77003.

Normally you would not assign an administration code for the contrast, but intrathecal contrast is one of the two exceptions (intra-articular being the other).
