What 62323 covers
This service involves placing a needle, or a catheter used only for the injection, into the lumbar epidural or subarachnoid space through an interlaminar approach, or into the sacral epidural space through the sacral hiatus. A non-neurolytic substance, commonly an anesthetic or steroid, is injected. A typical case is an epidural steroid injection for lumbar radiculopathy associated with disc herniation or spinal stenosis. Interventional pain physicians, anesthesiologists, physiatrists, and interventional radiologists perform these injections in offices, ambulatory surgery centers, and hospital outpatient departments using fluoroscopy or CT.
Report one unit for the lumbar or sacral region per session, even if multiple interspaces are accessed. Imaging guidance and contrast injection to confirm placement are included. Documentation should identify the approach, entry level, imaging modality, injected substance and dose, and contrast spread when contrast is used. The 0-day global period includes routine same-day pre- and postprocedure care; a significant, separately identifiable E/M service requires modifier 25 on the E/M code. In the same session, the highest-valued procedure is paid in full and other procedures are subject to the 50% multiple procedure reduction. Medicare does not pay an assistant at surgery and does not permit co-surgeon or team surgery billing.

How to choose
- 62322Epidural injectionLumbar or sacral, no imaging
- Both cover lumbar interlaminar or caudal injections; 62323 requires documented fluoroscopic or CT guidance, while 62322 is for injections performed without imaging guidance.
- 64483Transforaminal epidural injectionLumbar or sacral, first level
- 64483 uses a transforaminal approach at one lumbar or sacral level, with 64484 added for another level. 62323 uses an interlaminar or caudal approach and is reported once per session for the region.
- 62321Epidural injectionCervical or thoracic, image-guided
- 62321 covers an imaging-guided interlaminar injection with cervical or thoracic entry; choose 62323 for lumbar interlaminar or sacral caudal entry.
- 62328Lumbar punctureDiagnostic, with imaging
- 62328 is an imaging-guided diagnostic lumbar puncture to obtain cerebrospinal fluid. 62323 delivers a diagnostic or therapeutic substance into the epidural or subarachnoid space.
62323 billing questions
When is 62323 reported instead of 62322?
Use 62323 when fluoroscopy or CT guides the lumbar interlaminar or caudal injection. For the same injection without imaging guidance, report 62322.
Can fluoroscopy (77003) or epidurography be billed with 62323?
Imaging guidance and contrast injection used to confirm placement are included in 62323. Do not separately report 77003, 77012, or epidurography for that placement confirmation.
Is a caudal epidural steroid injection reported with 62323?
Yes. An imaging-guided injection through the sacral hiatus is covered, as is an imaging-guided lumbar interlaminar injection.
How many times can 62323 be billed if injections are given at two lumbar levels?
Report one unit for the lumbar or sacral region per session, regardless of how many interspaces are accessed. Transforaminal injections are coded by level with 64483 and, for an additional level, 64484.
Can an office visit be billed on the same day as 62323?
Routine pre-injection evaluation is included in the 0-day global period. Report a separate E/M only when its documentation supports a significant, separately identifiable service beyond the usual care for the injection; append modifier 25 to the E/M code.
Which code applies if a catheter is left in place for continuous infusion?
62323 covers injection through a needle or a catheter used only for that injection. For a lumbar or sacral indwelling catheter used for continuous infusion or intermittent bolus, use 62327 with imaging guidance or 62326 without it.
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.
