New York's health exchange is extending its registration deadline for the coming year by five days until Dec. 20. The state Health Department says the extension applies to enrolling or renewing health insurance coverage for the second year of the state-run marketplace. Officials say they're doing it because of the snowstorms that hit parts of the state last month, causing power outages and road closings in western New York. Since the open enrollment period began Nov. 15, they say more than 154,562 people have enrolled through the marketplace for the first time. New York's exchange enrolled 370,604 people with commercial and nonprofit insurers in the first year. Another 525,283 enrolled in Medicaid and 64,875 in the state's Child Health Plus coverage.
