Enrollment in the Essential Plan, a state-run and federally funded coverage plan with premiums of no more than $20 a month for people making up to twice the federal poverty level, has reached more than 760,000, up from about 710,000 at the same point last year, the state said. Enrollment in privately-operated qualified health plans, which are sold through the state healthcare exchange and eligible for federal tax credits, is at 170,000, up from 166,000 at this time last year.
