CVS Health / Aetna EDI and data integration
A guide to exchanging claim, eligibility, payment and enrollment data with CVS Health / Aetna: company facts from its website, what health insurers and payers typically exchange, and what to confirm before setup.
Overview
Understanding CVS Health / Aetna integration
Who this is for: Providers, billing services, clearinghouses, employers, brokers and benefits platforms that exchange data with CVS Health / Aetna.
Aetna, part of CVS Health, offers health insurance as well as dental, vision and other plans to individuals and families, employers and health care providers. Its website is aetna.com. It is also searched for as Aetna, CVS Health Aetna.
This page is an integration guide. It uses the public pages and documents of CVS Health / Aetna that are listed under Sources, which we read on November 10, 2026 and summarize in our own words; it does not reproduce them, and no private specification was used. Connection requirements usually come from CVS Health / Aetna itself, through its onboarding team, its companion guides or its partner portal, and they can differ by line of business, program, state and region.
What CVS Health / Aetna's own pages say: Aetna says it conducts electronic provider transactions exclusively in the HIPAA-mandated X12 version 5010. Aetna directs providers to its Availity provider portal for eligibility checks and mentions that they can also use one of its vendors. No Aetna companion guide or trading partner testing document was found on the pages read.
Health insurers and payers exchange administrative transactions with providers, clearinghouses, employers and brokers. HIPAA names the X12 version 5010 standards for these: the 837 claim, 835 payment and remittance advice, 270 and 271 eligibility, 276 and 277 claim status, 278 authorization, 834 enrollment and 820 premium payment. Payers commonly add their own rules in companion guides and offer portals as well as file exchange. The member and claim data involved is protected health information, so files need encrypted connections and an audit trail. Everything on this page that is not attributed to CVS Health / Aetna's own pages is general practice, not CVS Health / Aetna's published requirement; confirm each point with CVS Health / Aetna before you build maps or test.

Challenges
Common integration challenges
A companion guide per payer
Each payer adds its own rules to the HIPAA standards, so the same claim or enrollment file is mapped and validated differently for every payer.
Rejections and reconciliation
Rejected claims, denials and unmatched payments must be traced back to the source record and corrected.
Protected health information
Member and claim data must travel over encrypted connections with access control and a clear audit trail.
Confirm the current requirements
Document sets, versions and delivery rules change, and they come from CVS Health / Aetna directly, so confirm the current ones before building maps or testing.

Typical requirements
Which CVS Health / Aetna exchange applies to you
Typical requirements—confirm with your trading partner. This section is general practice for this type of insurer, not requirements published by CVS Health / Aetna. This guide does not imply approval, certification or a partnership.
Claims, eligibility and payments
Providers and billing services typically submit claims (837), check eligibility (270 and 271) and receive payment advice (835). These are provider transactions and are separate from employer enrollment and premium.
Enrollment and premium
Employers, brokers and benefits platforms send enrollment (834) and premium payment (820). Reinsurance or stop-loss data is a different exchange again.
Protected health information
Member and claim data is protected health information, so files need encrypted connections and access control. Many payers publish provider guides by plan or region; confirm which one applies to you.
Regions, states and affiliates
CVS Health / Aetna may operate through different legal entities, states and regions. Requirements, contacts and connection methods can differ by entity, state, region, line of business and program, so confirm which CVS Health / Aetna entity and region applies to you before you build or test.
