Aetna Better Health encourages providers to electronically submit claims. Please use the following Payor ID number when submitting claims electronicially to the health plan: Payor ID #128MI for both CMS 1500 and UB 04 forms.

WebConnect is our free provider claims submission portal via Emdeon Office. Emdeon Office is a contracted vendor used by Aetna Better Health of Michigan and Aetna Better Health Premier Plan for electronic claim submission, processing and support. To read the Webconnect manual click here (PDF).

Within the next two months, ConnectCenter will replace Emdeon Office, giving you a more reliable and more complete way to submit claims. You will be able to use your ConnectCenter and Emdeon Office accounts at the same time until 4/30/2021. After that date, most of your Emdeon Office account will be deactivated. However, we will provide continued access to old claims by allowing you to log in directly to the Reporting & Analytics feature, within Emdeon Office.

In order to ensure that you have as much time as possible to transition to ConnectCenter, we highly recommend that you start using it immediately. Change Healthcare has produced and made available the Getting Started with the Sign-Up process guide (PDF) guide to assist in general navigation and registration with ConnectCenter powered by Change Healthcare office.

Please review the guides below for verifying member eligibility and claim submissions.

Contact your Provider Services representative for more information on electronic billing.

Resubmitted claims should be clearly marked “Resubmission” on the envelope.

For out-of-network providers seeking payment of claims for emergency, post-stabilization and other services authorized by us, please refer to the policies and procedures in the provider manual.

EFT/ERA Registration Services (EERS)

Aetna Better Health of Michigan has partnered with Change Healthcare to introduce the EFT/ERA Registration Services (EERS), a better and more streamlined way for our providers to access payment services.

EERS offers providers a standardized method of electronic payment and remittance while also expediting the payee enrollment and verification process. Providers can use the Change Healthcare tool to manage ETF and ERA enrollments with multiple payers on a single platform.

How does it work?
EERS gives payees multiple ways to set up EFT and ERA in order to receive transactions from multiple payers. If a provider’s tax identification number (TIN) is active in multiple states, a single registration will auto-enroll the payee for multiple payers. Registration can also be completed using a national provider identifier (NPI) for payment across multiple accounts.
Providers who currently use Change Healthcare as a clearinghouse will still need to complete EERS enrollment, but providers who currently have an application pending with Change Healthcare will not need to resubmit. Once enrolled, payees will have access to the Change Healthcare user guide to aid in navigation of the new system.

How and when do I enroll?
All Aetna Better Health plans will migrate payee enrollment and verification to EERS. To enroll in EERS, please visit
