Aetna modified CPB 0180 covering vertebral axial decompression, effective September 26, 2025. HCPCS code S9090 is explicitly listed as not covered. Here's what billing teams need to do.
Aetna, a CVS Health company, updated Clinical Policy Bulletin 0180 governing vertebral axial decompression. The Aetna vertebral axial decompression coverage policy classifies S9090 (vertebral axial decompression, per session) as not covered for any indication listed in the bulletin. If your practice bills S9090 for VAD services to Aetna members, this modification puts those claims at direct risk. Two additional codes — CPT 97012 (mechanical traction) and CPT 64722 (nerve decompression) — appear in the policy as related codes. Understanding how Aetna treats each one differently is where this gets operationally important.

Aetna Vertebral Axial Decompression Coverage Policy: Coverage Criteria and Medical Necessity Requirements 2025
The core position in CPB 0180 Aetna is straightforward: vertebral axial decompression billed under HCPCS S9090 is not covered. Aetna does not recognize it as meeting medical necessity standards for any dorsopathy diagnosis in the M40.00–M54.9 ICD-10-CM range.
That range is broad. It includes degenerative disc disease, lumbar disc herniation, spinal stenosis, spondylosis, and a full spectrum of back and neck conditions. Aetna's position is that VAD performed as a distinct, separately billed service — the kind of treatment delivered on dedicated motorized decompression tables marketed under brand names — doesn't meet the clinical evidence bar for reimbursement.
This isn't a soft guidance document. Aetna's coverage policy labels S9090 as not covered for the indications listed in the bulletin. If you're billing S9090 and expecting reimbursement, expect a claim denial instead.
The policy does not list prior authorization as a path to coverage. There's no prior auth process described that would make S9090 billable. The coverage exclusion is categorical, not case-by-case.
Aetna Vertebral Axial Decompression Exclusions and Non-Covered Indications
S9090 is the code that carries the explicit not-covered designation in this policy. It describes vertebral axial decompression billed per session — the exact billing unit most VAD providers use.
This exclusion matters beyond just one code. Vertebral axial decompression has been marketed aggressively to patients as an alternative to surgery for herniated discs and chronic low back pain. Patients arrive with expectations. When a practice discovers mid-treatment that Aetna won't pay, it creates financial and patient relations problems that are entirely avoidable.
The real issue here is that some practices have been bundling or substituting CPT 97012 (mechanical traction) to capture reimbursement for what is functionally a VAD session. Aetna lists 97012 in this policy specifically as a "related code." That classification is a signal. It suggests Aetna is aware of the substitution pattern and is treating 97012 separately — not as a workaround pathway for VAD coverage.
CPT 64722 (decompression of unspecified nerve) appears in the policy as another related code. This code describes a surgical nerve decompression procedure. Its presence in CPB 0180 reflects that Aetna tracks both surgical and non-surgical decompression under this bulletin. It does not mean 64722 is covered as a substitute for S9090.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Vertebral axial decompression, per session | Not Covered | S9090, M40.00–M54.9 | Explicitly excluded for all indications listed in CPB 0180; no prior auth pathway described |
| Mechanical traction (as a related service) | Related code — separate coverage determination applies | CPT 97012 | Listed as related to CPB 0180; not a substitute billing path for VAD |
| Surgical nerve decompression (unspecified nerve) | Related code — separate coverage determination applies | CPT 64722 | Surgical procedure; listed as related to bulletin, not as VAD coverage |
| Dorsopathies (full range) | Diagnosis context for the policy | M40.00–M54.9 | These diagnoses do not make S9090 billable; Aetna's not-covered designation applies regardless of diagnosis |
Aetna Vertebral Axial Decompression Billing Guidelines and Action Items 2025
This policy became effective September 26, 2025. If you haven't already audited your charge capture and claim history, start now.
| # | Action Item |
|---|---|
| 1 | Pull all claims with S9090 submitted to Aetna on or after September 26, 2025. Any of those claims in a pending or processing status should be reviewed before they generate denials that age your AR. If they've already been denied, evaluate whether an appeal is viable or whether you're better served writing off the balance and correcting your process. |
| 2 | Remove S9090 from your Aetna charge master for VAD services. Don't wait for a denial to flag the error. Removing it from the charge master prevents future billing errors from staff who may not be aware of the effective date of this policy update. |
| 3 | Do not substitute CPT 97012 for S9090 as a workaround. Aetna's listing of 97012 as a related code in CPB 0180 suggests they're watching the substitution pattern. Billing 97012 for a service that is functionally a VAD session creates upcoding and claim integrity risk. If your practice provides mechanical traction as a genuinely distinct, documented service, bill it accurately — but make sure your documentation reflects what was actually delivered. |
| 4 | Review patient financial agreements for VAD services. If you continue to offer vertebral axial decompression to Aetna members, they need a clear advance beneficiary-style notice explaining that their plan does not cover this service and that they will be billed directly. Get the signature before treatment starts, not after. |
| 5 | Audit any bundled visits where S9090 and 97012 appear together. If your billing team has been reporting both codes on the same date of service for the same patient, Aetna may treat that as a claim integrity issue, not just a coverage question. Clean this up in your records before it becomes a payer audit. |
| 6 | If your practice uses dorsopathy ICD-10 codes (M40.00–M54.9) as primary diagnoses for VAD sessions, understand that those diagnoses don't change Aetna's position. The not-covered designation in CPB 0180 applies to S9090 regardless of the diagnosis code attached. Correct diagnosis coding won't override the exclusion. |
| 7 | Talk to your compliance officer if your practice volume of VAD billing to Aetna is significant. Repeated claim denials on a non-covered service — especially at high volume — can trigger payer scrutiny. If you've been billing S9090 to Aetna regularly, your compliance officer should know about this policy change and help you assess your exposure before September 26, 2025 claims cycle through to denial. |

CPT, HCPCS, and ICD-10 Codes for Vertebral Axial Decompression Under CPB 0180
Not Covered HCPCS Codes
| Code | Type | Description | Reason |
|---|---|---|---|
| S9090 | HCPCS | Vertebral axial decompression, per session | Explicitly not covered for indications listed in CPB 0180 |
Key ICD-10-CM Diagnosis Codes
| Code Range | Description |
|---|---|
| M40.00–M54.9 | Dorsopathies |
The ICD-10 range M40.00–M54.9 covers the full spectrum of dorsal conditions Aetna associates with vertebral axial decompression claims. This includes postural kyphosis, lordosis, scoliosis, degenerative disc disorders, cervical and lumbar disc disease, spondylosis, spinal stenosis, and back pain diagnoses. The breadth of this range reflects the wide variety of conditions for which VAD is marketed — and for which Aetna has uniformly declined coverage under this policy.
