Update: New Addresses for Claim Overpayment Refunds and Contractual Allowances

Posted September 13, 2019 (Updated October 9, 2019) (Updated November 4, 2019)

The effective date for the new addresses has changed. If you’ve mailed a claim overpayment refund to one of the new addresses below, it will be processed in a timely manner and does not need to be resent.

The description for the last address listed below has been changed from “Contractual Allowances for Non-UPP Professional Providers” to “Contractual Allowances for Non-UPP Facility Providers.

Beginning Dec. 1, 2019*, we will be using new addresses for remittance of claim overpayment refunds. If you do not participate in the Uniform Payment Program (UPP), we have a new address beginning Oct. 28, 2019*, for remittance of your monthly contractual allowances, if applicable.

To help avoid delays in the manual/paper refund process, please use the new addresses below. These new addresses may appear on the remittance forms you receive in the mail with refund requests.

Overpayment refunds and contractual allowances received at our old addresses will be forwarded for a minimum of 90 days. After the forwarding service ends, any payments submitted to the old addresses will be returned to the sender.

*Previous implementation dates were Oct. 1, 2019, and Oct. 4, 2019, respectively.
