ERA Enrollment Approved: Are You In-Network Yet?
By George Ruan • October 7, 2026
Last reviewed: October 7, 2026.
No. An ERA approval does not make you in-network. It means the payer will send electronic remittance advice (the 835 payment report) to your billing system. Network participation comes from a separate credentialing or contracting approval, with its own effective date, and you should not see patients as in-network until you have that.
This is one of the most common emails practices forward to us with a hopeful “Good to go?” The confusion is understandable: the notices come from enrollment vendors, use words like “approved,” and often name a company you never signed a contract with.

Why an Optum Email Can Be About Aetna
Aetna routes ERA and EFT enrollment through Optum’s Payer Enrollment Services. So an email from Optum titled “approved by the payer” can be about Aetna payment reports, not a UnitedHealthcare or Optum network contract. Read the enrollment details line in the body: it names the payer and the transaction, for example “Aetna - ERA.”
We have answered this question for a practice that read the email as a UnitedHealthcare approval, and for one that had deliberately declined an Optum contract. In both cases the email concerned only Aetna remittance delivery.
“Verified” Is Not “Approved”
Optum’s enrollment service sends more than one email for the same request, and the wording matters:
Verified: Optum checked the submitted information and is forwarding it to the payer. Nothing is approved yet. Optum’s own notice says processing can take up to six weeks.
Payer Received: the payer has the request and is reviewing it.
Payer Approved: the payer accepted the enrollment. You can now expect the ERA, the EFT, or both, exactly as listed in the email, and nothing more.
An ERA-only approval does not touch your bank account. When only ERA was requested, no bank account was enrolled and no EFT change was made. Check direct deposit as its own item.
Four Tracks That Move Separately
Network participation: the payer confirms the clinician or group is contracted for a named network, under the right tax ID, from a stated effective date.
Claim submission: your billing system can send 837P claims to this payer.
ERA: the 835 payment report reaches the right clearinghouse.
EFT: payments go to the right bank account by direct deposit.
CMS treats payment and remittance as distinct transactions, and SimplePractice’s enrollment FAQ likewise separates electronic enrollment from credentialing. An approval on one track is not evidence for any other.
What We See When These Tracks Cross
Payment setup can come first. Some payers want EFT and ERA in place before they will continue a network application. In those cases the payment approval is a real milestone, but the contract is still pending.
Network status can still be months away. Adding a new tax ID to a clinician’s existing UnitedHealthcare credentialing has typically taken two to three months in our experience, regardless of any payment enrollment approved in the meantime.
Out-of-network payments still need setup. Payers pay out-of-network claims too, so ERA and EFT can be worth enrolling before a contract exists. Some payment portals cannot be set up until the first payment is issued.
How to Confirm You Are Actually In-Network
Ask the payer’s provider-network or contracting team, not the enrollment vendor. Get written confirmation naming the clinician or group, the tax ID, the networks or products, and the effective date. Until then, keep scheduling and patient estimates on your current status. Once participation is confirmed, use the first-insurance-client checklist.
If the ERA approval is real but no remittances appear, that is a delivery question for your clearinghouse; see BCBSIL EFT Is Active but ERA or EPS Is Missing for a worked example.

Frequently Asked Questions
Does an Aetna ERA approval from Optum mean I joined UnitedHealthcare?
No. Optum runs the enrollment service Aetna uses for payment reports. Joining a UnitedHealthcare or Optum network is a separate credentialing application.
Why did I get an Optum enrollment email when I never signed up with Optum?
Your biller likely submitted an Aetna ERA or EFT request through Optum’s enrollment portal on your behalf. The email body lists the payer and transaction it concerns.
Can I read an Aetna EOB without ERA enrollment?
Yes. Aetna says providers can view electronic EOBs through Availity without enrolling in ERA, but that does not mean an 835 connection to your billing system exists.
