Submit Medicare Secondary Payer Claims Correctly the First Time!

If you're facing challenges related to MSP claim submissions for Medicare Part B, then this information is important for you. Ensuring that claims are submitted correctly the first time is crucial to avoid processing delays and possible rejections.

Here’s what you need to focus on to minimize errors with your MSP claims:

1. Verify Information Accuracy: Make sure all the details on the claim form are filled out completely and accurately. This includes double-checking MSP insurance type codes and ensuring they reflect the correct insurance plan information.

2. Follow ANSI Specifications: Make certain you are following the ANSI 837P specifications as outlined in the Medicare Secondary Payer Manual for Electronic Submitters/ANSI Specifications for 837P. Pay special attention to required fields and their correct formats.

3. Be Aware of Common Error Codes:

   • MA130 indicates missing, incomplete, or invalid information on the claim.

   • N245 points specifically to invalid or missing plan information from other insurance.

4. Populating MSP Insurance Type Code on Electronic Claims: Each MSP scenario requires a specific insurance type code. Be sure to use the correct one to specify the kind of secondary insurance involved.

5. Update Your Records Regularly: Confirm that your patients' insurance information is current. Patients’ other coverage details can change, and outdated information can lead to claim rejections.

6. Training and Resources: Ensure that your billing team is thoroughly trained on MSP rules and the submission process. By paying special attention to these areas, you can improve the accuracy of your submissions and reduce the likelihood of experiencing claim rejections.
