It turns out ObamaCare didn’t solve the problem of “pre-existing conditions” after all. It made premiums more affordable for people with chronic health conditions that are expensive to treat — but at the price of sticking them with unaffordable co-payments for their medications.

The nonprofit AIDS Institute is suing four Florida health insurers for discriminating against HIV/AIDS patients. The complaint says these patients now face prohibitive out-of-pocket drug costs. Sadly, most of the plans sold via ObamaCare all across the country have similar problems — leaving those with chronic diseases without affordable access to the specialty drugs they need.

The Affordable Care Act limits the degree to which insurers can charge higher premiums for sicker patients. But ObamaCare plans found a way around these rules: impose higher out-of-pocket costs for all or most specialty drugs.

Consider the Florida suit. Carl Schmid, the AIDS Institute deputy executive director, says the plans follow a “pattern where every single [HIV/AIDS] drug for some plans was on the highest tier, including generics.” Under these policies, drug costs for AIDS patients can exceed $1,000 a month.

And Florida’s hardly unusual. A new report from consulting group Avalere Health found that a large majority of all ObamaCare exchange plans include similarly high out-of-pocket costs for patients with certain illnesses.

The breakdown of Silver plans (the most popular category) is particularly revealing. In seven classes of drugs for conditions from cancer to bipolar disorder, more than a fifth of these plans require patients to shoulder 40 percent of the medicine’s cost.
