Are e-cigarettes, the popular battery-powered devices marketed as a smoking alternative, tobacco products?
How government regulators, insurance companies and customers each answer that question is key to deciding whether e-cigarette users will face higher health insurance premiums for their habit.
The Affordable Care Act allows insurers to tack on a higher premium to customers who use tobacco products. The charge can cost up to 50 percent of a client's premium and — more costly to some — cannot be subsidized by a federal tax credit.
But the 2010 law is silent on e-cigarettes, which were a nascent industry at the time, an omission that leaves insurers unsure how to view them and users in a precarious position.
Now the device has grown in popularity, with an estimated 20.4 million trying an e-cigarette sometime during 2013, said a government report.
E-cigarettes produce an odorless vapor that, like traditional cigarettes, contains nicotine. But federal regulators aren't sure whether to treat it as tobacco when it comes to advertising, banning sales to minors and when it comes to health insurance surcharges.
The Food and Drug Administration, which regulates cigarette smoking, has taken initial steps to suggest it will restrict e-cigarettes like other tobacco products but has yet to make a final ruling on the matter.
And the Centers for Medicare and Medicaid Services, which runs the online health insurance marketplaces, said it is still evaluating how health-policy issuers may treat e-cigarette users.
