What 64484 covers

This add-on reports an injection into the epidural space through a lumbar or sacral neural foramen at an additional spinal level. The clinician typically uses imaging guidance to position the needle near the affected nerve root and deliver medication for radicular pain, such as pain associated with disc disease or spinal stenosis. Pain specialists, anesthesiologists, and other clinicians who perform image-guided spine procedures commonly provide this service in an office or facility setting.

Report 64484 for each additional lumbar or sacral level treated after the first level, with 64483 for the initial level. The procedure note should identify the levels treated and support the additional injection. Imaging guidance is included in the injection service and is not separately reported for the same procedure. CMS treats this as an add-on code: it must be billed with its primary procedure and is paid within that procedure’s global period. When performed bilaterally and reported with modifier 50, CMS pays the bilateral procedure at 150%.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

64484 billing questions

How many units of 64484 should be reported?

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
