Medicare Set-Aside

A Medicare Set-Aside (MSA) is a designated allocation within a personal injury settlement intended to pay for future medical expenses related to the settled injury that would otherwise be covered by Medicare, preserving Medicare's secondary payer status and protecting the settling parties from future reimbursement liability. In mass tort settlements, MSA requirements can significantly reduce the net cash available to claimants and create complex administrative obligations that extend settlement timelines. Funders must account for MSA requirements in their underwriting because mandatory set-asides reduce the distributable settlement fund and may trigger CMS review and approval processes that delay disbursement by 6–18 months. Failure to properly structure MSAs exposes claimants, law firms, and in some cases funders to federal recovery actions by CMS for conditional payments made after settlement.

Because a mandatory MSA reduces the cash actually available for distribution and can trigger a CMS review process that delays disbursement by 6–18 months, funders factor MSA exposure into both the net recovery estimate and the expected timeline — two separate variables that both move against the funder simultaneously. Funders underwriting claimant cohorts with significant future medical needs treat MSA administrative delay as a near-certain event, not a downside scenario, and price accordingly.
