April 3, 2020, KHN, Shefali Luthra, Phil Galewitz and Rachel Bluth – As the coronavirus roils the economy and throws millions of Americans out of work, Medicaid is emerging as a default insurance plan for many of the newly unemployed. That could produce unprecedented strains on the vital health insurance program, according to state officials and policy researchers. Americans are being urged to stay home and practice “social distancing” to prevent the spread of the virus, causing businesses to shutter their doors and lay off workers. The Labor Department reported Thursday that more than 6.6 million people signed up for unemployment insurance during the week that ended March 28. This number shattered the record set the previous week, with 3.3 million sign-ups. Many of these newly unemployed people may turn to Medicaid for their families.
