In order to receive your ERA after your authorization agreement has been confirmed, you must contact your vendor or clearinghouse to arrange for the delivery of the CORE-compliant ERA.

NOTE: If your vendor or clearinghouse does not have an existing trading partner connection with Quartz, please have them complete, sign, and mail two original copies of this Electronic Trading Partner Agreement to this address:

Attn: EDI Dept.
840 Carolina Street
Sauk City, WI 53583

Once both originals are received, approved, and signed by Quartz, one of the originals will be mailed to the vendor or clearinghouse. Then, Quartz will complete one successful round of testing with this vendor or clearinghouse using the ERA claim tests for the provider seeking authorization. When this testing is complete, the enrollment process is confirmed.
