CPT 77003 describes fluoroscopic guidance and localization of a needle or catheter tip for spine or paraspinous diagnostic or therapeutic injections. For years it was billed alongside spinal injections. That has changed.
Which injection codes include imaging
| Code family | Procedure | Imaging included? |
|---|---|---|
| 62321, 62323 | Interlaminar epidural, cervical/thoracic and lumbar/sacral, with imaging | Yes |
| 62320, 62322 | Same procedures, without imaging guidance | No imaging used |
| 64479–64484 | Transforaminal epidural, by level | Yes (fluoroscopy or CT) |
| 64490–64495 | Paravertebral facet joint injections | Yes |
| 64633–64636 | Facet joint nerve radiofrequency ablation | Yes |
If imaging is used for an interlaminar epidural, the correct code is the "with imaging" version, not the "without imaging" code plus 77003.
Why this matters
- Denials: payers and NCCI edits bundle 77003 into these codes.
- Audit risk: routinely billing a separate imaging code on procedures that include it can look like unbundling.
- Lost revenue the other way: using a "without imaging" code when imaging was documented underbills the service.
Where separate guidance codes can still apply
Some spine and paraspinous procedures don't include imaging in their descriptors. In those cases 77003 may still be reportable when imaging is documented. Always check the current CPT descriptor and NCCI edits for the specific code pair before billing.
A quick audit
- Search the last six months of claims for 77003.
- List the primary procedure codes billed with it.
- Check each against the current descriptor. Any pair where imaging is included is a fix.
