QUESTION: CLAIMS: I file all my Medicare claims electronically except for Medicare Secondary Payer (MSP) claims, because I thought that I had to attach the primary Explanation of Benefits (EOB). Is this the correct process?

Answer

All MSP claims must be filed electronically. The HIPAA compliant ANSI X12 format allows the primary EOB information to be entered electronically. The primary EOB should be kept on file in your office. MSP claims are considered “initial” claims to Medicare and must be filed electronically. For more information on where to enter the primary EOB information contact your software vendor.
