Registering and getting started with Availity Essentials

Don’t forget! If your organization already has an Availity Essentials account, you do not have to register again to start utilizing services that are currently available for Mercy Care and Mercy Care Advantage providers.


Before you start, gather this information about your organization:

  • Physical and billing addresses
  • Tax ID (EIN or SSN)
  • NPI (if you have one)
  • Primary specialty/taxonomy
  • Check or EFT information from a health plan that you submit to (recommended)

Note that:

  • If your organization already has an account, ask the administrator to add you as a user.
  • You only need one registration per organization. Each user does not have to register for a separate Availity account. Adding a duplicate account request will delay the registration approval process.
  • The person who registers for the Essentials account will become the primary administrator for the organization, typically an office manager. This person will grant and maintain access to Essentials for your entire organization. If that is not you, please forward this information to the right person. 
  1. Click Register and complete the steps in the registration wizard.     Tip: Prior to initiating your registration application, we recommend you refer to the demo and quick guides located on this helpful registration landing page for registration guidance or tips.
  2. After you complete your registration, Availity will send you emails that include your next steps and temporary password. You may then begin adding other users for your organization.
  3. Refer to the Adding Users help topic on Availity Essentials to learn how your Availity administrators can add users, either one at a time, or with a spreadsheet.

Note: To view or print this help topic, you must be registered with Availity Essentials.
