Print Review Explanation Of Benefits An online printable Explanation of Benefits (EOB) is available for medical provider payments. The Explanation of Benefits allows you to obtain a detailed itemization of all payments included on a medical provider check (also known as "draft"). This will ensure you apply payments appropriately, which will save time for both you and NYSIF. To utilize this service, you need your Medical Provider Payee Tax ID Number, the NYSIF Check Number, and the last four digits of the Social Security Number for any claimant included on the check. NYSIF also offers a detailed Medical Billing Inquiry System that answers questions about the status of submitted medical bills.
