By October 2, six people had enrolled in the plan.
The paltry turnout is a sign of the many technical issues that plagued the HealthCare.gov enrollment website.
The documents provided to the House Oversight and Government Reform Committee showed that the six people enrolled with five separate insurance companies.
The House committee posted the findings online, which also showed that by October 3, 248 people had signed up.
A spokesperson for the Department of Health and Human Services declined to release the total number of Americans who have enrolled.
They added that they expect a large number of people will be enrolled by the December 15 deadline.
