Epidural and facet injections in 2026: count the level, don't pay twice for the picture

Two mistakes drain a pain-management practice more than any denial letter: billing fluoroscopy that is already inside the injection code, and counting medial branch nerves instead of facet joints. Here is the short answer, then a calculator that settles both at the point of coding.

Fluoroscopy Imaging guidance is bundled into 62321, 62323, the transforaminal 64479–64484, and the facet 64490–64495. Do not add 77003.

Level counting A facet joint is one level even though two medial branches are blocked to numb it. Count joints, not needles.

Where it hits The over-code shows up as doubled facet units and a stray 77003 line that NCCI silently strips, leaving revenue on the floor.

Pick the procedure, the region, and how many levels the physician treated. The panel returns the correct CPT string, tells you exactly where fluoroscopy is already included, and flags the medial-branch over-count before it leaves your queue.

The 2026 code families

Three families, one rule about the picture

AMA CPT 2026 keeps the same architecture: the injection code tells you whether imaging is built in. Learn which codes already own their fluoroscopy and the 77003 denial pattern disappears.

Interlaminar / caudal

Epidural, single injection

62320 · 62321 · 62322 · 62323

62320 cervical/thoracic, without imaging
62321 cervical/thoracic, with imaging
62322 lumbar/sacral, without imaging
62323 lumbar/sacral, with imaging

62321 & 62323 include fluoro/CT → no 77003

Transforaminal

Epidural, per level

64479 / 64480 · 64483 / 64484

64479 cervical/thoracic, first level
+64480 cervical/thoracic, each add'l level
64483 lumbar/sacral, first level
+64484 lumbar/sacral, each add'l level

Imaging guidance included in every unit

Facet / medial branch

Paravertebral joint / nerve

64490–64492 · 64493–64495

64490 / 64493 first level (joint)
+64491 / +64494 second level
+64492 / +64495 third & any additional
Reported per joint, not per nerve

Fluoro/CT bundled; third-level add-on billed once

The over-coding pattern

One joint, two branches, still one level

Each lumbar facet joint is innervated by two medial branches, so anesthetizing a single joint means two needle targets. Coding both as separate levels doubles the units. CPT counts the joint, not the branch.

Correct · per joint

L4-L5 & L5-S1 blocked

Two medial branches numb one joint = 1 level

Second joint = 1 level

2 joints → 64493 + 64494 (2 units)

Wrong · per branch

Same two joints, mis-counted

Each branch billed as its own level

Four needles read as four levels

4 "levels" → 64493 + 64494 + 64495 over-coded → audit + takeback

Medicare facet-joint intervention LCDs also cap the number of levels payable per session and per rolling year. The per-branch count trips both the CPT convention and those LCD frequency limits at once.

Where the money leaks

The four leak points on one claim

77003

The guidance line NCCI bundles into every code in this panel. Billed separately, it denies and drags the whole claim into review.

2×

The unit inflation when medial branches are counted as levels. The most common facet over-code in a pain practice.

Facet add-on stops at the third level (64492/64495), reported once for the third and beyond, not stacked per extra joint.

50 / RT·LT

Bilateral facet work is a modifier decision, not a doubled unit. Payer policy decides modifier 50 versus RT/LT split.

The 2026 guidelines this panel runs on

AMA · CPT 2026

Epidural injection codes 62320–62327

The 2026 code set keeps imaging guidance built into 62321 and 62323, and into the continuous-infusion catheter codes 62324–62327. The "with imaging" descriptor is the instruction not to add a separate guidance line.

CMS · National Correct Coding Initiative

NCCI bundling of fluoroscopic guidance (77003)

NCCI procedure-to-procedure edits pair 77003 with the epidural, transforaminal, and facet injection codes as bundled guidance. The edit strips the line; a modifier does not rescue guidance that CPT already includes.

AMA CPT + Medicare LCDs

Medial branch block and level-counting rules

Facet codes 64490–64495 are reported per joint. Medicare's facet-joint intervention LCDs layer on the level and per-year frequency limits that govern how many of those units a payer will actually cover.

CMS · CY2026 Final Rule

Medicare Physician Fee Schedule

The CY2026 Physician Fee Schedule sets the RVUs and conversion factor behind each of these codes. Getting the units and guidance right is what protects the reimbursement the fee schedule assigns.

Quick reference

Fluoroscopy: bundled or separate?

Code	Procedure	Unit basis	Fluoro 77003
62321 / 62323	Interlaminar/caudal epidural, with imaging	Per session	Bundled
62320 / 62322	Interlaminar/caudal epidural, no imaging	Per session	Report if used
64479–64484	Transforaminal epidural	Per level	Bundled
64490–64495	Facet joint / medial branch	Per joint	Bundled

Stop coding the picture twice

ASP-RCM Solutions runs pain-management claims through exactly this logic before they ever reach a payer. Our coders count joints, honor the bundling edits, and appeal the level-limit denials with the guideline citations above already loaded. That is the difference between a clean 62323 and a 77003 takeback letter.
