RESUMEN
Little information exists to inform stakeholders' efforts to screen for, address, and risk-adjust for the health-related social needs (HRSNs) of Medicare Advantage (MA) enrollees, particularly those not dually Medicaid-Medicare eligible and those younger than age sixty-five. HRSNs can include food insecurity, housing instability, transportation issues, and other factors. We examined the prevalence of HRSNs in 2019 among 61,779 enrollees in a large, national MA plan. Although HRSNs were more common among dual-eligible beneficiaries, with 80 percent reporting at least one (average, 2.2 per beneficiary), 48 percent of non-dual-eligible beneficiaries reported one or more, indicating that dual eligibility alone would have inadequately captured HRSN risk. HRSN burden was unequally distributed across multiple beneficiary characteristics, notably with beneficiaries younger than age sixty-five more likely than those ages sixty-five and older to report having an HRSN. We also found that some HRSNs were more strongly associated with hospitalizations, emergency department visits, and physician visits than others. These findings suggest the importance of considering the HRSNs of dual- and non-dual-eligible beneficiaries, as well as those of beneficiaries of all ages, when exploring how to address HRSNs in the MA population.
