ALBANY, N.Y. (AP) _ New York's health exchange has already received 174,000 completed applications for new insurance coverage starting next year, accounting for a large share of initial signups nationally under the Affordable Care Act.

Obama administration officials have said about 500,000 applications have been filed through federal and state exchanges since they launched three weeks ago with some systems plagued by technical problems. But they haven't said how many people have managed to enroll.

In California, officials say 126,000 people have started applications but won't release figures on completed applications or enrollments until mid-November.

New York addressed initial website problems by quadrupling capacity on the marketplace that includes low-cost plans and possible government subsidies. It says Wednesday that 37,030 New Yorkers have completed the process and fully enrolled with individual insurers.
