Overview

Aetna ASO is carrier administration of employer-funded medical plans. Aetna’s mid-size funding brochure describes an administrative services contract with benefit-design flexibility and population health management, positioned for roughly 301–5,000 eligible employees, with fixed administration costs plus incurred claims and the ability to retain surplus. Large-group and public/labor self-funded relationships are administered by Aetna Life Insurance Company and named affiliates. This is distinct from Aetna Funding Advantage, a level-funded product.

Why it matters It is Aetna’s core self-funded ASO path for larger groups—separate from Funding Advantage level-funding and from Meritain, the affiliated TPA brand.

Target buyer: Mid-size to large self-funded employers and public/labor groups that want Aetna/CVS Health administration rather than a standalone TPA.
Pricing model: Administrative service fees plus employer-funded claims; optional stop-loss and NAP savings-share fees; No public PEPM. NAP fees are described as a percent of savings in addition to administrative service fees. Exact percents are in proposal/renewal documents, not a public rate card.

Overview

Aetna ASO is administrative-services-only medical for employers that fund their own claims. Aetna Life Insurance Company and affiliates administer large-group and public/labor self-funded medical relationships. The January 1, 2026 underwriting disclosures name Innovation Health Insurance Company, Banner Health and Aetna Health Insurance Company, and Allina Health and Aetna Insurance Company among those affiliates.

A March 2024 mid-size funding brochure (CVS Health / Aetna) describes a self-funded option for companies with 301 to 5,000 eligible employees: payments of fixed administration costs plus incurred claims, comprehensive plan-design customization, point-solution flexibility, full surplus retention, multiple network types, and optional prescription carve-out. It also notes that some state mandates and premium taxes may not apply to self-funded plans.

Aetna Funding Advantage is a different self-funded / level-funded product (employer-insured, Aetna-administered, with integrated stop-loss). This page is the ASO / administrative-services contract, not Funding Advantage.

Aetna is part of CVS Health.

Key Capabilities

Claims administration and member services under an administrative services contract.
Utilization management, credentialing, and call center, sometimes delegated to third parties with Aetna oversight (disclosures).
Population health management and customizable plan design (brochure).
Optional Rx carve-out.
National Advantage Program: contracted rates for many non-network claims (including some emergency and hospital-based specialist claims) plus optional Facility Charge Review, Itemized Bill Review, and (on some plans) Professional Claims Repricing Service.

Integrations & Ecosystem

Network access is through Aetna network products; the brochure says multiple network types are available. Out-of-network pricing can use NAP. Delegated arrangements may include ACOs, network vendors, specialty groups, and medical service organizations. Meritain Health is a related Aetna/CVS Health TPA brand and is a separate directory entry.

A complete public list of ASO-compatible PBMs and point solutions is not on the pages reviewed.

Pricing

Fees are proposal- or renewal-based. The brochure describes fixed administration costs plus incurred claims. Disclosures state that NAP retains a percent of savings in addition to administrative service fees; the public PDF does not publish that percent as a list rate. Stop-loss, when purchased, is a separate premium.

Notes & Limitations

Do not confuse with Aetna Funding Advantage (level-funded surplus-share product).
Meritain is the affiliated TPA; ASO is the carrier administrative-services contract.
Group-size “best fit” of 301–5,000 in the mid-size brochure is marketing guidance, not a hard underwriting floor/ceiling for all Aetna self-funded deals.
Availability and network options vary; confirm with Aetna or a broker.
Vendor-reported savings or surplus examples in marketing PDFs are not used as independent facts here.
