According to the ABC News report, the state-based exchanges created under the law fared a little better: 79,391 people selected plans.
The Obama Administration says a total of 106,185 people have selected a qualified health plan through the state and federal marketplaces. That number is about 80% lower the projected target of 494,620 the Health and Human Services (HHS) department had expected according to an internal HHS memo obtained by AP and ABC News.
Health and Human Services Secretary Kathleen Sebelius says she expects things to improve.
California's new health insurance exchange tentatively enrolled 35,000 people during its first month of operation, a fraction of the eventual goal in the state with the nation's largest uninsured population.
A report released Wednesday by the U.S. Department of Health and Human Services also showed that California determined about 80,000 lower-income people would be eligible for expanded Medicaid coverage under the national health care overhaul.
California counts nearly 7 million people without health coverage. An estimated 2.3 million are expected to enroll in a health plan through the new agency, known as Covered California, by 2017.
Earlier this month Covered California said about 2.5 million people had visited its website.
