Aetna modified CPB 0603 covering total-body CT screening, effective December 4, 2025. Here's what billing teams need to do.
Aetna, a CVS Health company, classifies total-body CT screening — including full-body, whole-body, and ultrafast electron-beam CT — as experimental, investigational, and unproven under CPB 0603 Aetna system. HCPCS code S8092 is the primary code affected by this Aetna total-body CT screening coverage policy, and it is explicitly listed as not covered for any indication within the bulletin. If your practice or imaging center submits claims for S8092, you need to understand exactly what this policy says before December 4, 2025.

Aetna Total-Body CT Screening Coverage Criteria and Medical Necessity Requirements 2025
The short version: Aetna does not cover total-body CT screening. Full stop.
CPB 0603 Aetna system classifies whole-body CT, full-body CT, and ultrafast (electron-beam) CT performed as screening services as experimental, investigational, or unproven. This is not a prior authorization issue. Prior authorization won't save you here — there is no pathway to coverage for this indication under the Aetna total-body CT screening coverage policy.
The policy is explicit that total-body CT has not been shown to be effective as a screening test. That's the medical necessity threshold Aetna applies — and this service fails it. Your billing team cannot document around this. You cannot write a stronger letter of medical necessity and expect reimbursement. Aetna's position is categorical.
This matters because patients sometimes request these scans after seeing direct-to-consumer imaging center advertising. A physician orders one, the imaging center bills S8092, and your billing team is left chasing a claim that was never going to pay.
Aetna Total-Body CT Screening Exclusions and Non-Covered Indications
HCPCS code S8092 — described as electron beam computed tomography, also known as ultrafast CT or cine CT — is the only code listed in CPB 0603, and it falls entirely in the "not covered" column.
Aetna's language is unambiguous. The payer considers total-body CT screening "experimental, investigational, or unproven." That three-part classification is deliberate. It signals that Aetna has reviewed the evidence and found it insufficient to support coverage under any clinical scenario framed as screening.
The real issue here is scope. The policy covers the entire category of total-body CT screening — not just specific clinical presentations or patient populations. There is no carve-out for high-risk patients, no exception for specific diagnoses, and no indication-specific coverage pathway. If the CT is performed as a screening service and it covers the whole body, Aetna will not cover it.
This is different from targeted CT imaging ordered for a specific symptom or diagnosis. A chest CT for a pulmonary nodule is a separate clinical and billing scenario. CPB 0603 is about screening — asymptomatic patients, no specific clinical indication, broad surveillance intent. Don't confuse the two in your charge capture or your documentation.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Total-body / whole-body CT screening (asymptomatic patients) | Not Covered — Experimental, Investigational, or Unproven | S8092 | No prior authorization pathway exists; categorical exclusion |
| Full-body ultrafast (electron-beam) CT screening | Not Covered — Experimental, Investigational, or Unproven | S8092 | Applies regardless of patient risk profile or ordering rationale |
| Cine CT performed as a screening service | Not Covered — Experimental, Investigational, or Unproven | S8092 | Alternative code terminology for the same excluded service |
Aetna Total-Body CT Screening Billing Guidelines and Action Items 2025
The policy is clear. Your job now is to make sure your systems reflect it before December 4, 2025.
| # | Action Item |
|---|---|
| 1 | Flag S8092 in your charge capture system as non-covered for Aetna members. Set a hard stop or alert that fires when this code is billed against an Aetna plan. This is a claim denial waiting to happen, and catching it before submission saves your billing team the rework. |
| 2 | Audit claims submitted in the past 12 months for S8092 against Aetna. If you have submitted these claims and received denials, review your appeal strategy. Given the categorical "experimental and investigational" designation, medical necessity appeals will not succeed. Escalating these to legal or compliance is the right call. |
| 3 | Update your front-end eligibility and benefits verification scripts. When a patient requests a total-body CT, your scheduler or benefits team should flag Aetna coverage before the patient arrives. Patient responsibility conversations are much easier before the scan than after the claim denies. |
| 4 | Train your ordering providers on this coverage policy. Physicians who order these scans — whether in response to patient requests or as part of wellness programming — need to know that Aetna total-body CT screening billing will not generate reimbursement. Set expectations before the order is placed. |
| 5 | Review your patient financial agreements. If your facility performs total-body CT screening and markets it to patients with Aetna coverage, update your consent and financial agreement language. Patients should acknowledge in writing that this service is not covered by their plan and that they are responsible for the full cost. Talk to your compliance officer about how your state's advance beneficiary notice requirements (or commercial plan equivalents) apply here. |
| 6 | Check for plan-level variation within Aetna. CPB 0603 applies across Aetna's clinical policy framework, but individual employer group contracts sometimes vary. Your billing guidelines should include a step to verify that the specific Aetna plan your patient holds doesn't have a unique rider or supplemental benefit. This is rare, but it happens. If you're not sure how this applies to your payer mix, loop in your compliance officer or billing consultant before the effective date. |

CPT, HCPCS, and ICD-10 Codes for Total-Body CT Screening Under CPB 0603
Not Covered / Experimental Codes
| Code | Type | Description | Reason |
|---|---|---|---|
| S8092 | HCPCS | Electron beam computed tomography (also known as ultrafast CT, cine CT) | Not covered for total-body CT screening indications listed in CPB 0603 — classified as experimental, investigational, or unproven |
Covered CPT Codes
This policy lists no covered CPT codes. CPB 0603 exists solely to define the non-coverage position for total-body CT screening.
Key ICD-10-CM Diagnosis Codes
CPB 0603 does not list specific ICD-10-CM codes. The exclusion applies categorically to the screening service regardless of diagnosis code. No diagnosis code combination will establish medical necessity for S8092 under this policy.
Why This Policy Matters More Than It Looks
On the surface, CPB 0603 looks like a simple non-coverage bulletin for a niche service. But total-body CT screening is growing in the direct-to-consumer market. Companies like Prenuvo have normalized the idea of whole-body MRI and CT as annual wellness tools, and patients with commercial insurance — including Aetna plans — are asking their physicians to order these scans with increasing frequency.
That creates real exposure for imaging centers and ordering practices. The patient believes their insurance will cover it. The physician orders it. Your billing team submits S8092. Aetna denies it. Now you're collecting from a patient who didn't expect a bill.
The Aetna total-body CT screening coverage policy isn't going to change based on patient demand. Aetna's position is grounded in the evidence base, and the evidence hasn't shifted. Prepare your operations accordingly.
