Transparency in Coverage

Claims Payment Policies & Other Information: Retroactive denials

Some claims may be retroactively denied, even after the member has obtained services from the provider.

A retroactive denial is the reversal of a previously paid claim, through which the member then becomes responsible for payment.

There are ways to prevent this from occurring. You can:

  • Notify promptly of changes that could impact your eligibility or your premium amount owed.

  • Submit requested documentation to and/or (issuer name) promptly or within time constraints.

  • Pay your monthly premiums on time

Surprise Billing

When you get emergency care or get treated by an out-of-network provider at an in-network hospital or ambulatory surgical center, you are protected from surprise billing or balance billing. For more information on surprise billing, click the following link: Balance Billing Disclaimer


Members may obtain a refund of premium overpayment by notifying of changes that could impact eligibility or your premium amount owed and then contacting Customer Service at 855-447-2900.

Please note that in some situations, changes to eligibility must be received from before the CO-OP can refund an overpayment.
