CPT code 62322 – Lumbar epidural injection billing guide

Key takeaways

CPT Code 62322 covers a lumbar or sacral interlaminar epidural injection without imaging guidance. Cervical, transforaminal and image-guided injections take other codes.

Using imaging guidance switches the correct code to 62323, the paired with-guidance code. You can’t bill 62322 plus a separate imaging add-on.

A procedure note that leaves out the spinal level or the approach is a common denial trigger for this code family.

Medicare pays about $146 for 62322 in a non-facility setting in 2026. Verify your local rate with the CMS Physician Fee Schedule lookup before billing.

CPT Code 62322: official descriptor and procedure overview

CPT Code 62322 is the AMA’s designated code for a lumbar or sacral interlaminar epidural injection without imaging guidance. The substance can be an anesthetic, antispasmodic, opioid, steroid or other solution, and the code applies whether the intent is diagnostic or therapeutic.

Three clinical parameters define eligibility for this code:

• Spinal level: lumbar or sacral only. Cervical and thoracic levels are covered by 62320 (without imaging) and 62321 (with imaging).
• Approach: interlaminar. The needle passes between two adjacent vertebral laminae to enter the epidural space. Transforaminal approaches belong to the 64479-64484 family.
• Imaging guidance: absent. If fluoroscopy or CT guidance is used during the injection, the correct code is 62323, not 62322 with a separate imaging add-on.

Read those three facts off the note in that order, and the code follows from them, as the grid below shows.

The injectate may be a corticosteroid, a local anesthetic, saline, or a combination. What it may not be is a neurolytic agent. Neurolysis requires a separate code and cannot be billed under 62322. Correct billing for this code family starts with recording those three parameters in the procedure note.

What CPT 62322 covers and what it excludes

The code covers a specific, bounded set of clinical scenarios. Anything outside those boundaries requires a different code.

A common billing mistake is appending a separate fluoroscopy code alongside 62322. Payers treat imaging guidance as bundled into 62323. Billing 62322 plus a fluoroscopy code will trigger a bundling edit, not two payments.

CPT 62322 vs 62323: the imaging guidance distinction

CPT 62322 and 62323 describe the same interlaminar lumbar or sacral epidural injection. The only clinical difference is whether imaging guidance was used during the procedure.

The procedure note is the deciding document. If the note says fluoroscopy was used to confirm needle placement, 62322 cannot be billed. The note must be explicit about the absence of imaging when 62322 is the intended code.

CPT 62322 vs 64483: interlaminar vs transforaminal approach

The most consequential coding confusion in lumbar epidural billing is selecting between the interlaminar and transforaminal code families. Approach technique determines the code, not injectate, indication, or level alone.

Because 64483 always requires imaging guidance, there is no transforaminal counterpart to 62322. A practice billing 64483 without documentation of fluoroscopy or CT guidance will face immediate denial.

The full interlaminar epidural CPT code family: 62320-62323

CPT Code 62322 belongs to a four-code interlaminar epidural family organized by spinal level and imaging status. Coders selecting the correct code from this family need to know both variables before reaching for the code book.

For the transforaminal family (64479-64484), every code requires imaging guidance, and add-on codes cover additional levels. CPT Code 62322 has no add-on code and is reported once per session, however many levels are injected (its MUE is 1). If a second level is injected, report 62322 once and document each level in the note.

ICD-10 diagnosis codes that support medical necessity for CPT 62322

Payers require a paired ICD-10-CM diagnosis code that establishes medical necessity. The table below lists the codes most frequently submitted with CPT Code 62322. Note that specific payer Local Coverage Determinations (LCDs) issued by Medicare Administrative Contractors may define additional or more restrictive criteria for which diagnoses qualify.

Many payers require documentation that conservative treatment failed (typically 6 weeks of physical therapy or analgesics) before approving an epidural injection. Verify current LCD criteria through the relevant Medicare Administrative Contractor for the practice’s state, as criteria differ across regions.

Check the MAC’s epidural steroid injection LCD before scheduling a Medicare patient. These LCDs generally require imaging guidance for steroid injections, so coverage for a non-imaged 62322 with steroid is often limited or non-covered. The same caution applies to 62320.

Prior authorization requirements for CPT 62322

Prior authorization (PA) requirements for CPT Code 62322 vary significantly by payer type. Insurance eligibility verification before scheduling shows whether the plan needs an authorization while there is still time to request one.

• Traditional Medicare (Fee-for-Service): does not currently require prior authorization for CPT 62322, but does require the procedure to meet LCD medical necessity criteria for coverage.
• Medicare Advantage plans: PA is commonly required. Managed care organizations including eviCore Healthcare administer PA programs for many MA plans that cover epidural injections.
• Commercial payers: PA requirements vary widely by insurer and plan year. Many commercial payers require documented failure of conservative therapy before approving a lumbar ESI.
• Medicaid: requirements differ by state. Some state programs require PA; others treat epidural injections as covered services subject to medical necessity review post-payment.

PA requirements change annually. Verify authorization status directly with each payer before scheduling the procedure. Document the authorization number in the patient record and include it on the claim form where required.

Documentation requirements: what the procedure note must include

A clean claim submission for CPT Code 62322 depends entirely on what the procedure note records. Missing a single element is enough for a payer to deny or downcode the claim.

• Spinal level: state the specific vertebral level accessed (e.g. L4-L5, L5-S1). “Lumbar” alone is insufficient for many payers.
• Approach technique: document “interlaminar approach” explicitly. Do not leave technique implicit in the procedure description.
• Absence of imaging guidance: the note must affirmatively state that fluoroscopy, CT, or other imaging guidance was not used. Omitting this creates ambiguity that payers resolve in their favor.
• Injectate identity and volume: name the drug (e.g. methylprednisolone acetate 80 mg), dose, and volume injected.
• Clinical indication: reference the diagnosis (e.g. L4-L5 disc herniation with radiculopathy) and confirm it meets the payer’s medical necessity criteria.
• Patient response or tolerance: briefly note whether the procedure was tolerated well and any immediate clinical observation.

A frequent documentation failure is leaving out the statement that imaging guidance was not used. Without it, a coder reviewing the note later cannot confidently select 62322. The claim then sits in a work queue, or goes out as 62323 for imaging the physician never performed.

Medicare and payer reimbursement rates for CPT 62322

Medicare pays for CPT Code 62322 under the Medicare Physician Fee Schedule (MPFS), which is updated annually on January 1. Rates differ by setting and geographic location.

The non-facility figure is 4.36 total RVUs multiplied by the CY2026 conversion factor, which gives about $146 at either the $33.4009 or $33.5675 rate. These figures are national averages.

Geographic Adjustment Factors (GAFs) applied by each Medicare Administrative Contractor shift rates up or down, sometimes significantly in high-cost urban markets. Always verify current rates using the FastRVU 2026 RVU lookup or the CMS fee schedule search tool before building a reimbursement model.

Commercial payers set their own fee schedules, typically expressed as a percentage of MPFS. Rates often run between 110% and 160% of Medicare for in-network spine procedures, though this varies considerably by contract.

Tracking electronic remittance processing for 62322 claims shows billing staff when a payer is consistently paying below contracted rates. It also gives them the documentation to start a contract dispute.

Top reasons CPT 62322 claims are denied

Denial patterns for CPT Code 62322 cluster around the same root causes across payers. Structured denial management workflows catch most of these before the claim age-out period expires.

• Wrong code selected: billing 62323 when no imaging guidance was used, or 64483 when the approach was interlaminar. Approach technique controls the code, whichever family the physician usually bills.
• Missing or ambiguous documentation: when the note skips the spinal level, the approach or the imaging status, coders can’t confirm the code selection. Payers who audit these claims deny them.
• Prior authorization not obtained: Medicare Advantage and commercial payers require PA for many patients. Billing without an authorization number on the claim is an automatic denial for those plans.
• Medical necessity not established: the ICD-10 code isn’t on the payer’s LCD coverage list, or the record doesn’t document failed conservative treatment.
• Neurolytic agent billed under 62322: billing the injection of a neurolytic substance under 62322 is a coding error. A separate code category applies, and the error triggers a clinical audit risk.
• Unbundling fluoroscopy: appending a separate imaging code when fluoroscopy was used is incorrect. The correct response is to bill 62323 instead of 62322 plus an imaging code.

Billing tips and compliance considerations for CPT 62322

These pre-submission checks address the denial causes above before the claim leaves the practice. Build them into the procedure note template, so the clinician records each element at the time instead of a coder chasing it the next day.

• Documentation checklist at time of service: before the patient leaves the room, confirm the note records spinal level, approach, imaging status, injectate and clinical indication. A templated procedure note that prompts for these fields prevents most 62322 denials at their source.
• Modifier usage: when a significant, separately identifiable E/M service happens on the same date as 62322, append modifier 25 to the E/M service. Reserve modifier 59 for distinct procedural services, subject to NCCI edits.
• Bilateral considerations: the 62322 descriptor does not include a bilateral designation. If the same injection is performed bilaterally, document the clinical rationale clearly and consult the payer’s LCD to determine whether separate billing is supported.
• Global period: CPT 62322 carries a 000-day global period. The global covers the day of the procedure only, with no postoperative days. Related E/M visits on a later date can be billed separately without a modifier, subject to medical necessity documentation.
• AAPC compliance resources: the AAPC Codify CPT lookup includes coverage rules and common pairing guidance for the 62320-62323 family. Billing staff can use it when payer-specific policies are unclear.

Review the medical claims clearinghouse submission process alongside the documentation requirements above. A clearinghouse that checks claims against CPT edit logic catches bundling errors and missing modifiers before the claim reaches the payer. That cuts the rework of correcting and resubmitting claims.

How claims management software supports CPT 62322 billing

In many pain practices, 62322 billing happens after the procedure. A coder reads the note, rekeys the claim into a clearinghouse portal, then checks payer websites for status and remittances.

Pabau, the practice management and EHR platform we build, keeps the procedure note, the diagnosis and the claim on one patient record. Its pain practice claims software submits claims through the Claim.MD clearinghouse integration to thousands of US payers, then tracks their status.

Staff run real-time eligibility checks before the injection and post ERA remittances when payment lands. A procedure note template with prompts for level, approach and imaging status helps the clinician record the facts that decide the code.

Conclusion

CPT Code 62322 is straightforward once the note locks three facts: lumbar or sacral level, interlaminar approach, and no imaging guidance. Coding errors come from notes that leave one of those open, and from habit in teams that bill transforaminal codes more often.

Before your next non-imaged lumbar injection, check two points. Does the note state each fact in plain words? And does the patient’s MAC LCD cover a non-imaged steroid injection at all? If either answer is no, fix it before the procedure date, or confirm whether image-guided 62323 is the covered option.
