Health insurance enrollment has declined among people who do not qualify for financial help under Obamacare, new federal data show.  The data released by the Centers for Medicare and Medicaid Services on Monday show that enrollment declined by 1.2 million people, or 24%, between 2017 and 2018 among people with incomes too high to qualify for Obamacare subsidies and who therefore face the full brunt of premium cost increases. In contrast, in the same period, enrollment ticked up among those with subsidized coverage by 300,000 people.
