Having health coverage, even when you didn’t have it before the Affordable Care Act, still may mean you can’t get the medicines you may need.

Insurance companies call it “benefit design,” but consumer watch-dog and patient safety groups call it “adverse tiering.” Those of us on the front lines of patient care know it simply as bad medicine. That is, the choices your prescriber presents you for treatment of your chronic health condition may be less about his or her professional judgment and more about what your insurance plan is willing to pay.
