TLDR; this article walks you through the instructions to update the clearinghouse on an existing enrollment, and add a user to an existing enrollment.
Overview
Payerenrollservices.com is a tool through Change Healthcare used by many payers to manage ERA and EFT enrollments.
You must have a Change Healthcare login to access payerenrollservices.com.
Only one admin can be associated per TIN unless a user is added after an initial enrollment is completed and approved.
Submitting a new enrollment
Log in to https://payerenrollservices.com
Select Enroll New TIN
Enter Provider Information
Note: the provider information must match exactly the name and address on file with the IRS. If it does not, you may need to upload a 147C or CP575 IRS letter to the enrollment for verification purposes.
Note: if the TIN has already been registered with a payerenrollservices.com account, you will be notified on this screen and will need to have the account admin update the clearinghouse information before enrollment can be submitted.
