An interlaminar epidural steroid injection is billed using the 62322/62323 series. The difference between the codes comes down strictly to the use of imaging guidance.
62322 vs 62323
- 62322: Injection, interlaminar epidural, lumbar or sacral; without imaging guidance.
- 62323: Injection, interlaminar epidural, lumbar or sacral; with imaging guidance (fluoroscopy or CT).
If the physician uses fluoroscopy, you must bill 62323. Like the transforaminal codes, you cannot bill the fluoroscopy code (77003) separately.
Medical Necessity
Medicare requires strong medical necessity for epidural steroid injections, typically requiring documentation of radicular pain (e.g., M54.16 - Radiculopathy, lumbar region) that has failed conservative therapy.
NCCI Edits
These codes are not billed per level. Whether the physician injects one interlaminar space or two, you only bill the code once per session.
