Beginning next year, the annual out-of-pocket limits for all health plans sold in the (Obamacare) health insurance exchanges will be $7,150 for an individual and $14,300 for a family. To put those numbers in perspective, a $10-an-hour employee only earns about $20,000 a year.

One way to help families meet the burden of these medical expenses is with a Health Savings Account. But because the requirements for HSAs are so rigid, roughly four out of five plans sold in the exchanges are incompatible with them. One of the most nettlesome rules is the requirement that HSA plans cover only “preventive care” below the deductible. To compete for customers, especially young healthy enrollees, the insurers believe they need to make more services available with a minimum of out-of-pocket costs.

Things are about to get much worse. New rules and regulations, which become mandatory in 2018, will impose minimum and maximum deductibles and out-of-pocket limits that are inconsistent with the HSA rules.
