TL;DR: The Centers for Medicare & Medicaid Services modified NCD 124 governing vertebral axial decompression (VAX-D), effective March 7, 2026. The coverage position is unchanged — VAX-D remains non-covered under Medicare — but billing teams need to understand exactly why claims fail and how to handle patient inquiries correctly.

CMS Vertebral Axial Decompression Coverage Criteria and Medical Necessity Requirements 2026
The CMS vertebral axial decompression coverage policy under NCD 124 is unambiguous: VAX-D does not meet Medicare's medical necessity standard, and no claim will be reimbursed.
The Centers for Medicare & Medicaid Services cites insufficient scientific data to support the clinical benefit of VAX-D. That's not a soft exclusion or a "submit with documentation" situation. It's a hard no at the National Coverage Determination level — which means it applies uniformly across every Medicare Administrative Contractor jurisdiction in the country.
VAX-D treats symptomatic lumbar disk problems using pelvic and cervical traction connected to a specialized decompression table. The technology has been around for decades. The coverage policy has been just as consistent: no coverage, no exceptions, no pathway through prior authorization. If you're billing Medicare for VAX-D, you're generating claim denials on every single line.
The medical necessity question here isn't complex — CMS has already answered it. The question for your billing team is whether your processes are set up to prevent these claims from going out in the first place.
Prior authorization won't help here. There's no prior auth pathway that unlocks coverage for a procedure CMS has designated as unsupported by scientific evidence. Some teams waste time pursuing prior auth on non-covered services, assuming approval will protect them. It won't. NCD 124 is a blanket exclusion.
CMS VAX-D Exclusions and Non-Covered Indications
NCD 124 covers one indication: lumbar disk problems with associated pain. And it covers it with a flat denial.
VAX-D is non-covered for all patients, all diagnoses, and all clinical presentations under Medicare. There are no carve-outs for severity, for prior treatment failure, or for documentation of medical necessity. The coverage policy does not recognize any scenario in which VAX-D becomes a billable Medicare service.
This matters because some practices assume a procedure is non-covered only when billed incorrectly — wrong modifier, wrong diagnosis code, wrong place of service. With VAX-D under NCD 124, the procedure itself is the problem. No amount of documentation will change the reimbursement outcome.
The real issue here is patient exposure. Patients with chronic lumbar disk pain are often desperate for relief and willing to try anything. If your practice offers VAX-D and has Medicare patients in that population, you have a financial counseling obligation before treatment begins — not after.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Symptomatic pain relief from lumbar disk problems via VAX-D | Not Covered | No specific codes listed in NCD 124 | CMS cites insufficient scientific evidence. No exceptions. ABN required before service. |
| Cervical traction component of VAX-D | Not Covered | No specific codes listed in NCD 124 | Traction delivered via the VAX-D table is part of the non-covered service. |
| Any VAX-D service regardless of diagnosis or severity | Not Covered | No specific codes listed in NCD 124 | NCD 124 applies nationwide. No MAC-level override exists. |
CMS VAX-D Billing Guidelines and Action Items 2026
Here's what your billing team needs to do right now.
| # | Action Item |
|---|---|
| 1 | Audit your charge master for any VAX-D service codes. Pull every charge description tied to spinal decompression, axial decompression, or VAX-D-branded treatments. Flag anything that could be submitted to Medicare. Do this before March 7, 2026. |
| 2 | Issue Advance Beneficiary Notices (ABNs) for every Medicare patient before providing VAX-D. This is not optional. Without a properly executed ABN, you cannot bill the patient if Medicare denies — and Medicare will deny. The ABN must be signed before the service, not after. Train your front desk and clinical coordinators on this now. |
| 3 | Remove VAX-D from any Medicare fee schedule or superbill templates. If it's on a superbill, someone will bill it. Take it off. Route VAX-D services through a cash-pay or self-pay workflow that is completely separate from your Medicare billing guidelines. |
| 4 | Review any outstanding claims for VAX-D services billed to Medicare. If claims went out and are pending, expect denials. Do not resubmit. Pull those accounts and move them to patient-pay status — but only if valid ABNs were in place. If ABNs weren't obtained, your compliance officer needs to be in the room for that conversation. |
| 5 | Update your patient financial counseling scripts. Medicare patients asking about VAX-D need to know upfront that this is a cash-pay service with zero Medicare reimbursement. Set that expectation before scheduling, not at checkout. This reduces disputes, complaints, and potential fraud exposure. |
| 6 | Confirm your MAC's position. NCD 124 is a national determination, so there's no local coverage determination or LCD that overrides it. But your Medicare Administrative Contractor may have issued supplemental guidance or billing instructions. Check your MAC's website for any updates tied to NCD 124 in 2026. |
If you're unsure how NCD 124 intersects with your specific patient mix or practice setup, talk to your compliance officer before the effective date of March 7, 2026.

CPT, HCPCS, and ICD-10 Codes for Vertebral Axial Decompression Under NCD 124
Not Covered / Non-Reimbursable Services
The policy data for NCD 124 does not list specific CPT or HCPCS codes. This is significant. CMS's non-coverage designation applies to the VAX-D procedure and technology as a whole — not to a discrete set of billable codes.
What this means in practice: there is no "VAX-D code" that, if avoided, makes a related service billable. The non-coverage applies to the procedure regardless of how it's coded. Some practices attempt to bill related traction codes for services performed on a VAX-D table. CMS's position under NCD 124 treats the VAX-D table and its traction delivery as part of a single non-covered treatment.
If you're attempting to bill general lumbar traction codes for sessions that are, in substance, VAX-D treatments, that's a coding and compliance risk. VAX-D billing under any code for Medicare patients produces the same outcome: claim denial and potential fraud exposure if the underlying service is VAX-D.
Talk to your billing consultant or compliance officer before attempting to code VAX-D-adjacent services for Medicare. The absence of specific codes in NCD 124 does not create a billing workaround. It closes one.
What the Absence of Specific Codes Tells You
NCD 124 not listing specific codes is itself a policy signal worth understanding.
When CMS lists explicit codes in an NCD, it's drawing a precise line. Covered codes get paid under defined criteria. Non-covered codes get denied. Practices can build charge capture rules around those distinctions.
When CMS issues a blanket non-coverage determination without specific codes — as it does here — it's saying the technology is non-covered, full stop. No code bypasses the determination. This puts the compliance burden squarely on your clinical and billing teams to recognize when a service is VAX-D, regardless of what's on the superbill.
Train your coders to flag spinal decompression sessions that use a VAX-D table. If the equipment is VAX-D, the claim is non-covered under Medicare, and the patient should have been counseled before scheduling.
The Broader Pattern: Why CMS Keeps This NCD Active
CMS doesn't archive NCDs like NCD 124 when a technology falls out of fashion. It keeps them active — and updates them — because practitioners keep billing.
The modification to NCD 124 effective March 7, 2026, isn't changing the coverage position. It's maintaining it in the active policy record. That sends a signal: CMS is still seeing enough VAX-D billing activity to warrant keeping the NCD current.
This is the same pattern you see with other unproven therapies — electrostimulation combinations, certain thermal therapies, and older spinal technologies. The NCD stays on the books because the billing doesn't stop. And as long as the billing continues, the denials and potential fraud referrals continue with it.
If your practice has been billing VAX-D to Medicare under any code, stop now. The effective date of March 7, 2026 is your deadline for having clean processes in place. Don't wait to see if denials trigger a more serious audit.
