WASHINGTON, D.C. (WDTN) – Saturday, January 15 is the last day to sign up for healthcare coverage under the Affordable Care Act plan.

About 9 in 10 U.S. residents currently have health insurance through a mix of employer, public and individual plans, the Associated Press reports, but 28 million people remain uninsured even as COVID-19 cases continue to rise. Most of these uninsured people would be eligible for taxpayer-subsidized coverage, but are unaware of these options, surveys show.

“Dependable health care coverage is in reach at affordable rates,” said Chiquita Brooks-LaSure, head of the Centers for Medicare and Medicaid Services.

After the January 15 deadline, people can only sign up for coverage under special enrollment periods such as after losing a job or when dealing with a change in family circumstances such as the birth of a child or divorce, Healthcare.gov says. For more information on qualifying events, click here.

Those who sign up by Saturday’s midnight deadline will be covered starting on Tuesday, February 1.
