The documents were produced by the contractors involved in HealthCare.gov to comply with the House Oversight Committee's subpoena.
On the morning of Oct. 2, administration officials and contractors were told that six people successfully enrolled in Obamacare using HealthCare.gov. By the following morning's meeting, that number had gone up to 248.
The memos from meetings about HealthCare.gov were produced in response to subpoenas issued to the contractors by the House Oversight Committee Chairman Darrell Issa, R-Calif. Issa has also subpoenaed the Health and Human Services Department.
How many people have signed up for the new coverage in the month after the botched rollout of the Affordable Care Act website is unclear. HHS officials have said repeatedly that they will make monthly enrollment data public, and expect the first report to come mid-November.
The numbers from the HealthCare.gov meetings don't include totals from the 14 states that do not use the federal exchange site, and the states have been more successful than the federal government in their enrollment efforts. In Washington state, 35,528 people enrolled as of Oct. 21. But 87 percent of those sign-ups were for Medicaid. The Congressional Budget Office projects 9 million Americans will enroll for Medicaid in 2014.
The administration has pushed back, telling CBS News it won't discuss enrollment data because it doesn't have any. HHS Secretary Kathleen Sebelius gave a similar reason when she declined to share enrollment figures at a Congressional hearing earlier this week.
"We do not have any reliable data around enrollment, which is why we haven't given it to date," Sebelius said.
Sebelius has until noon on Nov. 13 to respond to Issa's subpoena.
