Abstract
Because Medicare beneficiaries can qualify for Medicaid through several pathways, duals who newly enroll in Medicaid may have experienced various financial and/or health changes that impact their Medicaid eligibility. Alternatively, new enrollment could reflect changes in awareness of the program among those previously eligible. Using monthly enrollment data linked to Health and Retirement Study survey data, we examine financial and health changes that occur around the time new Medicaid participants enter the program, and we compare those with changes experienced by both those continuously enrolled in Medicaid and those not enrolled. We find that Medicaid entry is often timed with a marked increase in out-of-pocket medical expenses, a substantial decrease in assets for some, and increases in activities of daily living (ADL) limitations. We also observe financial changes among persons continuously enrolled in Medicaid. Our results inform discussions about Medicaid eligibility policies and potential gaps in the protection that Medicaid offers from financial risk.
