One in six Obamacare customers could lose plans

It’s hard, if not impossible, to calculate precisely how many people will see their Obamacare plans canceled next year, since neither insurers nor the Centers for Medicare and Medicaid Services have comprehensively reported insurers’ market share by state or county.

But it could be about one in six Obamacare customers, or 17 percent, using enrollment numbers reported by insurers.

Aetna and UnitedHealthcare have 838,000 and 795,000 marketplace customers, respectively. Humana has 875,700 customers, although that includes customers in individual market plans off the exchanges.

Those customers total 2.5 million people, although some of them live in the handful of states where the insurers will keep selling plans next year. But they still comprise a significant portion of the 11 million Americans who have bought Obamacare plans in the marketplaces.
