Coding problems that led to coverage and billing troubles for thousands of consumers using Connecticut's online insurance marketplace will be fixed in Maryland's version of the technology, officials said today. Maryland officials had been preparing to use the technology underlying the Connecticut exchange after ditching their own glitch-prone software. They still expect the new Maryland Health Benefit Exchange website to be operating smoothly in November, when the next round of consumers will be allowed to buy health coverage. "We remain on schedule," Isabel FitzGerald, the state secretary of information technology, tapped to oversee development of the new website, told the exchange board this afternoon.
