A groundbreaking study highlights the critical connection between maintaining access to subsidized prescription drug programs and the survival rates of low-income seniors. Researchers from the University of Pennsylvania and Harvard have uncovered that when older adults lose Medicaid coverage, they are also at risk of losing a vital federal subsidy known as the Medicare Part D Low-Income Subsidy (LIS). This loss can significantly impact their ability to afford necessary medications.

By examining nearly one million low-income Medicare beneficiaries who experienced the termination of their Medicaid coverage, the researchers identified a notable increase in mortality rates. The study utilized a unique approach by comparing two groups: those who lost Medicaid early in the year and consequently lost LIS within seven to twelve months, and those whose LIS was terminated later, after thirteen to eighteen months. The findings revealed a 4% higher mortality rate among individuals who lost access to LIS earlier compared to those who retained it longer. Moreover, specific subgroups, such as those requiring expensive treatments like HIV antiretroviral therapy, faced even more severe risks, with mortality rates rising by 22%.

Maintaining continuous healthcare coverage is not only a matter of administrative efficiency but also a life-saving necessity for millions of Americans. The research underscores the importance of ensuring stable enrollment in both Medicaid and the LIS for vulnerable populations. With over half of individuals regaining Medicaid eligibility within a year, it suggests that many were mistakenly removed from the program despite qualifying. As policymakers deliberate on potential reforms to Medicaid, preserving access to essential medications through consistent coverage must remain a priority to safeguard public health and reduce preventable deaths.
