What CPT code do you suggest for the injection portion of the cisternogram, 62311? "DESCRIPTION OF PROCEDURE: Lower back was localized with intermittent fluoroscopy at the L3-4 level. The L3-4 level was marked, prepped, and draped in the usual sterile fashion. 5 mL of 1% Xylocaine was infiltrated into the skin and subcutaneous soft tissues of the lower back at the L3-4 level. Under fluoroscopic guidance, a 3.5 inch, 20 gauge spinal needle was slowly guided into the dural sac at the L3-4 level, yielding spontaneous return of clear cerebrospinal fluid. A shielded syringe continuing 1.5 mCi indium 111 DTPA was attached to the hub of the needle and injected intrathecally. The stylet was replaced, and the needle was removed."
