The wait for proposed rulemaking related to Medicare Secondary Payer (MSP) compliance obligations regarding future medical services in liability settlements continues. Although the Department of Health and Human Services issued their initial notification of proposed rulemaking in the fall of 2018, the target date has been moved several times and is currently set for October of 2021. However, focusing solely on the notice of proposed rules will cause a practitioner to overlook the impact of important MSP compliance changes taking place with Section 111 Mandatory Insurer Reporting obligations on settlements.
