Here's more fallout from the health care law: Until now, customers could walk into an insurance office or go online to buy standard health care coverage any time of year. Not anymore. Many people who didn't sign up during the government's open enrollment period that ended Monday will soon find it difficult or impossible to get insured this year, even if they go directly to a private company and money is no object. For some it's already too late. With limited exceptions, insurers are refusing to sell to individuals after the enrollment period for HealthCare.gov and the state marketplaces.
