Product line not on the agreement
Commercial, Medicare Advantage, and Medicaid are separate Aetna networks. Only the listed product is in network.
Medicare Advantage
Aetna Medicare Advantage credentialing
Aetna's Medicare Advantage plans sit inside CVS Health and run credentialing through Availity. We confirm PECOS, submit the request, and track the file to a confirmed roster load.
Overview
How Aetna Medicare Advantage credentialing actually works
Aetna, part of CVS Health, offers Medicare Advantage HMO, PPO, and dual-eligible plans across most of the country. Like every Medicare Advantage carrier, Aetna requires an active Medicare Part B enrollment in PECOS with a correct reassignment before participation can be processed.
Aetna runs participation requests and roster maintenance through Availity. The portal is precise about entity data, and requests that do not match NPPES and PECOS on NPI, TIN, taxonomy, and address are held rather than corrected.
Commercial Aetna participation does not automatically include the Medicare Advantage product line, and Aetna Better Health (Medicaid) is a third, separate network. Confirming the specific product on the executed agreement is the step that prevents months of unexplained denials.

How the engagement runs
Week 1 — Medicare first
Medicare Advantage participation requires an active Medicare Part B enrollment (PECOS) with a correct reassignment. If PECOS is not clean, nothing downstream moves — we fix that first.
Week 1–2 — Application package
CAQH attested and authorized to the plan, licensure, DEA, board certification, malpractice, and the plan's participation request submitted with the correct group TIN and locations.
Week 4–12 — Credentialing committee
Primary source verification, then committee review on the plan's published cycle. We track the file weekly and answer every information request immediately.
Week 8–16 — Contract, load, verify
Contract and fee schedule executed, roster load confirmed, effective date captured, and the provider directory checked so patients can actually find the provider.
Common failure points
Why Aetna Medicare Advantage applications stall or deny
These are the patterns we see most often when we take over a stalled file for this payer.
PECOS not active or reassignment missing
Medicare Advantage participation rests on Part B enrollment. A pending PECOS file blocks everything downstream.
Availity entity mismatch
TIN, NPI, taxonomy, or address differences between the request, NPPES, and PECOS hold the file with no clear message.
Board certification documentation missing
Aetna verifies certification or an accepted equivalency. Missing documentation is a common committee deferral.
Directory attestation missed
Skipped attestations can suppress the directory listing even while the contract is active.
Panel status unchecked
Some markets close panels by specialty. Confirming status first avoids filing into a closed network.
FAQ
Aetna Medicare Advantage credentialing questions
Does commercial Aetna participation include Medicare Advantage?
Not automatically. Medicare Advantage is a separate product line and must be listed on the executed participation agreement.
Do I need PECOS first?
Yes. An active Medicare Part B enrollment with a valid reassignment to the billing group is a prerequisite.
How long does Aetna Medicare Advantage credentialing take?
Typically 60 to 120 days from a complete submission, plus roster load time after execution.
Which portal does Aetna use?
Availity handles participation requests, demographic updates, and directory attestations in most Aetna markets.
Is Aetna Better Health the same network?
No. Aetna Better Health is the Medicaid managed care line and is credentialed and contracted separately from Medicare Advantage.
How often does Aetna re-credential?
Every three years, with interim attestations that affect directory visibility.
