TL;DR: Aetna, a CVS Health company, modified CPB 0523 on November 27, 2025, confirming that car-ride simulators for infantile colic are not a covered benefit under any Aetna plan. Here's what billing teams need to know.
This update to the Aetna car-ride simulator coverage policy makes two things clear. First, devices like the SleepTight Infant Soother are experimental and unproven under CPB 0523 Aetna standards. Second, they don't qualify as durable medical equipment (DME) — so even a well-coded claim won't get paid. The sole diagnosis code in play is ICD-10-CM R10.83 (Colic [infantile]). If your practice or any affiliated provider has been billing for these devices, stop and read this.

Aetna Car-Ride Simulator Coverage Criteria and Medical Necessity Requirements 2025
Aetna's coverage policy under CPB 0523 is unambiguous: car-ride simulators do not meet medical necessity criteria. Full stop.
Aetna defines durable medical equipment as devices used primarily for a medical purpose. Car-ride simulators fail that test on two counts. They are not primarily medical devices, and their main function — promoting sleep — is useful in the absence of illness or injury.
That second point is where the medical necessity argument collapses. To meet Aetna's DME definition, a device must be medically required to treat a diagnosed condition. Promoting sleep in an otherwise healthy infant doesn't clear that bar, even when the infant carries a diagnosis of R10.83 (Colic [infantile]).
There are no prior authorization pathways for these devices under CPB 0523. Prior authorization presupposes a category of covered items — and this category doesn't exist under Aetna's coverage policy. Requesting prior auth here won't open a door; the door isn't there.
Reimbursement for car-ride simulators is not available under any Aetna commercial plan governed by this policy. If a plan document or rider suggested otherwise, that's worth escalating to your compliance officer before any claim goes out the door.
Aetna Car-Ride Simulator Exclusions and Non-Covered Indications
CPB 0523 applies the experimental, investigational, or unproven designation to car-ride simulators — the same classification Aetna uses when clinical evidence doesn't support a treatment's effectiveness.
This matters for billing teams because "experimental" claims don't fail quietly. They generate claim denial notices that can trigger audits or downstream payer scrutiny. A denied claim for an experimental device looks different on a payer's radar than a routine coding error.
The SleepTight Infant Soother is specifically named in the policy. If you see this device — or any similar car-ride simulator — documented in a patient's record and someone on your team is considering billing for it, that claim should not go out.
The reasoning in the policy goes beyond a simple coverage exclusion. Aetna's position is that no evidence exists to establish effectiveness for this approach in treating infantile colic. That's a higher bar to clear than a standard non-covered exclusion — it signals that even new evidence would need to be substantial and peer-reviewed before Aetna revisits this.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Infantile colic treated with car-ride simulator | Not Covered / Experimental | R10.83 | Fails DME definition; device not primarily medical in nature |
| Car-ride simulator for sleep promotion | Not Covered | R10.83 | Use in absence of illness or injury explicitly cited as disqualifying |
Aetna Car-Ride Simulator Billing Guidelines and Action Items 2025
The effective date of November 27, 2025 is already in effect. These steps apply now.
| # | Action Item |
|---|---|
| 1 | Audit any open or pending claims involving R10.83 with a DME component. Pull claims coded with R10.83 that include any device billing. If a car-ride simulator appears in the record, pull the claim before it submits. |
| 2 | Remove car-ride simulator devices from your charge capture entirely. Don't leave them in your system as a billable item. There is no code combination that will result in reimbursement under any Aetna plan for this device. Having it in charge capture invites accidental submission. |
| 3 | Educate your clinical documentation team. Pediatricians and family medicine providers who recommend these devices to parents may not realize the billing dead end this creates. A brief note in your internal guidelines prevents future confusion. |
| 4 | Do not attempt DME billing workarounds. Some billers try alternate HCPCS codes when a device lacks a direct match. That approach won't work here. Aetna's coverage policy explicitly excludes this device category from DME — the issue is definitional, not a coding gap. |
| 5 | Flag any payer correspondence that contradicts CPB 0523. If a plan document, benefits summary, or payer representative suggests these devices are covered, escalate to your compliance officer immediately. Plan-level documents don't override the clinical policy bulletin, but the discrepancy needs to be resolved before any claim goes out. |
| 6 | Check your DME supplier relationships. If your practice refers patients to a DME supplier for these devices and the supplier bills Aetna on your patient's behalf, the claim denial still affects the patient experience. Alert your referral partners to this policy. |

CPT, HCPCS, and ICD-10 Codes for Car-Ride Simulators Under CPB 0523
Covered CPT and HCPCS Codes
The policy data for CPB 0523 lists no covered CPT or HCPCS codes for car-ride simulators. No code combination produces a covered claim for these devices under Aetna's coverage policy.
Not Covered / Experimental Devices
CPB 0523 does not assign specific HCPCS codes to car-ride simulators. This is significant. It means there is no "miscellaneous DME" code path that applies here. The device category itself is excluded — not a specific code.
If you encounter billing guidelines from a device manufacturer suggesting a particular HCPCS code, those billing guidelines do not override Aetna's CPB 0523 exclusion. Manufacturer-suggested codes are not payer authorizations.
Key ICD-10-CM Diagnosis Codes
| Code | Description |
|---|---|
| R10.83 | Colic [infantile] |
R10.83 is the only diagnosis code in this policy. It will appear on any claim attempting to bill for infantile colic treatment. But the presence of a valid diagnosis code doesn't create a covered benefit. The device exclusion applies regardless of how accurately the diagnosis is coded.
A Note on Scope: Why This Policy Is Narrow but Still Worth Watching
CPB 0523 covers a small device category. Most billing teams won't encounter car-ride simulator claims often — or at all. But this update is worth noting for two reasons.
First, the DME definition argument Aetna uses here applies broadly. Any device that primarily promotes wellness, sleep, or comfort — rather than treating a specific medical condition — faces the same definitional barrier. This is the same framework Aetna applies across other consumer-adjacent device categories.
Second, the "experimental" designation has staying power. Aetna won't lift it without published clinical evidence showing effectiveness. If a patient or provider pushes back on a denial and asks about appeals, the answer is that an appeal won't succeed without peer-reviewed evidence that doesn't currently exist. Set expectations accordingly.
If you manage billing for a pediatric practice and your providers recommend these devices frequently, loop in your compliance officer to make sure your documentation and billing workflows reflect the updated CPB 0523 policy.
