Medicare Secondary Payer Payment Calculator

The MSP payment calculator is intended to provide an approximation of what an MSP payment may be for assigned claims. This calculator does not reflect applicable coinsurance, deductible, or other deductions. MSP claims are calculated line-by-line. Any billing and/or refunds should be done based on your remittance advice and not the results of this calculator.

Here’s what you'll need to get started:

• Your Billed Amount
• Medicare Fee Schedule Allowed Amount
• Primary Insurance Allowed Amount
• Primary Insurance Paid Amount
• Obligated To Accept payment in Full (OTAF), if applicable

Note: The OTAF amount will indicate that there is a discount that the beneficiary is not responsible for. To calculate the OTAF, use the primary explanation of benefits, take the billed amount and minus any discounts or adjustments.

Enter the information in the Enter Payment Data fields and select Calculate.
