The Medicare secondary payer (“MSP”) law requires Medicare to be the “secondary” payer of health benefits for Medicare beneficiaries where another entity is the “primary” payer of health benefits. Determining whether another entity is “primary” and when Medicare is “secondary” has often been difficult due to the wide range of circumstances in which another party may be responsible for a Medicare beneficiary’s health expenses, the number of potential parties involved, and the somewhat confusing terminology in the law itself. As a result, Congress enacted new rules to enhance the enforcement of the MSP law. Any entity that might pay settlements to Medicare-eligible plaintiffs that would cover any health expenses, or might otherwise compensate Medicare beneficiaries for health expenses as part of group health insurance, workers’ compensation, or any other arrangement or plan, needs to become familiar with these new rules. Specifically, Congress now requires such entities to (1) register as a responsible reporting entity (“RRE”), and (2) electronically report information to the Centers for Medicare & Medicaid Services (“CMS”).CMS will use this information to track and recover health expenses it incurred on behalf of Medicare beneficiaries but that another entity, as a primary payer under the existing MSP requirements, may be responsible for paying.  To read the full alert, click here.
