Digital health will continue to be a focus under recently confirmed Secretary Becerra‘s leadership at the Department of Health and Human Services.

The COVID-19 pandemic has created significant challenges for all Americans, particularly for its most vulnerable populations, including the elderly and people with disabilities in Medicare. The Centers for Medicare & Medicaid Services (CMS) recently reported that 21% of fee-for-service (FFS) Medicare enrollees have stated they are forgoing non-COVID-19 related care due to the pandemic. Avalere conducted analyses to determine if a similar decrease in utilization is occurring in Medicare Advantage (MA) and assess the potential impact of deferred care on MA enrollees and plans.

Stakeholders should examine each of these areas closely as they respond to CMS.
