What 64493 covers

A physician, commonly a pain specialist, anesthesiologist, or radiologist, uses fluoroscopy or CT to guide an injection to a lumbar or sacral paravertebral facet joint or the nerves supplying it. The injection may be diagnostic, such as evaluating suspected facet-mediated back pain, or therapeutic. The code represents one spinal level, not one needle or one side; the documented target must be in the lumbar or sacral region.

Report 64493 for the first treated level. Document the spinal level, side, target, clinical reason, and image guidance. The imaging guidance is part of the service. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

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.

How does CMS handle other procedures in the same session?

The highest-valued procedure is paid in full, while other procedures are subject to the standard multiple-procedure reduction. Same-day preoperative and postoperative care is included in the 0-day global period.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. CMS does not permit co-surgeons or team surgery for this code.

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.
