"Transforaminal epidural steroid Injection at the levels of L4, L5. Procedure: Needle was advanced under fluoroscopic guidance using an oblique view just inferior to the pedicle of the L5: right. The final needle position was into the inferior one-third of the foramen. The fluoroscopy view was changed to the AP and lateral views, and the needle position was confirmed to be within the foramen. Then 2 mls of isovue 200mg/ml dye was injected under AP view without DSA and confirmed adequate spread along the nerve root and in the epidural space. There was no evidence of intravascular uptake or intrathecal spread on imaging. A lateral view was also taken confirming adequate epidural spread. This was repeated at the right L4 level as well. At this point, 3mL total volume, consisting of 1mL of 40mg/mL of Triamcinalone was injected along with 2.0 mls of 1% lidocaine per level." Is this considered one level L4-L5 for 64483 or two levels for 64483 and 64484?
