Millions of Americans in high-deductible health plans associated with HSAs may find it easier to access insulin, inhalers and other treatments for chronic health problems under guidance released last week by the Trump administration. Currently, people in high-deductible plans with pretax health-savings accounts have to pay down their deductible before their insurance covers treatment for chronic diseases such as diabetes or high blood pressure. The rule change will allow insurers to begin providing coverage for those treatments, such as glucose or blood-pressure monitors, before the deductible is paid.
