Data on Insurance Reported by Researchers at Johns Hopkins University (Trends In Medicare Advantage Participation Among Commercial Insurers): Insurance

2024 APR 01 (NewsRx) -- By a News Reporter-Staff News Editor at Health Policy and Law Daily -- Current study results on Insurance have been published. According to news reporting out of Baltimore, Maryland, by NewsRx editors, research stated, “Commercial health insurers can participate in the rapidly growing Medicare Advantage (MA) market, which may affect network formation and prices in traditional commercial insurance markets. We aim to quantify the prevalence and growth of commercial insurers participating in MA within the same state.”

Funders for this research include NIH National Institute on Aging (NIA), Arnold Ventures.

Our news journalists obtained a quote from the research from Johns Hopkins University, “Repeated cross-sectional analysis of Clarivate’s Interstudy enrollment data comprising the universe of insurers in the United States from 2015 to 2021. We calculated the share of employer-sponsored insurance (ESI) enrollees covered by an insurer offering MA in their state in 2015, 2017, 2019, and 2021. We documented this share across states, years, and the state’s 2015 tercile. Between 2015 and 2021, the share of ESI enrollees covered by an insurer offering MA in the same state increased from 83.5% to 95.3%. This growth was concentrated in states with initially low rates in 2015 (lowest 2015 state tercile, <= 70.5%), in which the share grew from 47.6% to 87.9%. In 2015, 23.5% of states had a share greater than 90.0% compared with 74.5% in 2021. By 2021, almost all ESI enrollees were covered by insurers who participated in MA in the same state.”

According to the news editors, the research concluded: “Future research should investigate how insurer participation in MA affects network formation and prices in commercial markets.”

This research has been peer-reviewed.
