What 64483 covers

At a lumbar or sacral neural foramen, the clinician advances a needle under fluoroscopy or CT to deliver local anesthetic, corticosteroid, or both near the affected nerve root and epidural space. Typical indications include radicular leg pain associated with a herniated lumbar disc or foraminal stenosis; an S1 foraminal injection is a sacral example. Interventional pain physicians, anesthesiologists, and physiatrists perform these injections in offices, ambulatory surgery centers, and hospital outpatient departments. Contrast may be used to confirm needle position and epidural spread.

Report one unit of 64483 for the first lumbar or sacral level, whether unilateral or bilateral; report 64484 for each additional level. Fluoroscopic or CT guidance is included. Document the treated level, side, guidance method, contrast findings when contrast is used, and injectate. For both sides at the same level, report 64483 with modifier 50; CMS pays bilateral procedures at 150% of the unilateral amount. The 0-day global includes routine same-day preoperative and postoperative care. When multiple procedures are performed in one session, CMS pays the highest-valued procedure in full and other eligible procedures at 50%. CMS does not pay an assistant at surgery; 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.

64483 billing questions

How are two lumbar levels reported?

Report one unit of 64483 for the first level and one unit of 64484 for the additional level. Document the side treated at each level.

How is a bilateral injection at one level billed?

Report 64483 with modifier 50 when the same level is injected on both the left and right. CMS pays the bilateral procedure at 150% of the unilateral amount.

Can fluoroscopy or CT guidance be billed separately?

No. Fluoroscopic or CT guidance is included in 64483, so codes such as 77003 or 77012 are not reported separately for the same injection.

What if the injection is done under ultrasound guidance only?

64483 describes an injection performed with fluoroscopic or CT guidance. For ultrasound-guided lumbar or sacral transforaminal injections, 0230T describes the first level and 0231T describes each additional level.

Is an S1 transforaminal injection reported with this code?

Yes. An injection through the S1 foramen is sacral and falls under 64483 rather than the cervical or thoracic first-level code 64479.

Is a same-day E/M visit separately reportable?

Routine same-day preoperative and postoperative care is included in the 0-day global. A significant, separately identifiable E/M service beyond that care may be reported with modifier 25.

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.
