The Murky Politics of Mind-Body

Now a critical moment has been reached in a 15-year debate in statehouses and in Congress over whether treatment for problems like depression, addiction and schizophrenia should get the same coverage by insurance companies as, say, diabetes, heart disease and cancer.This month, the House passed a bill that would require insurance companies to provide mental health insurance parity. It was the first time it has approved a proposal so substantial.The bill would ban insurance companies from setting lower limits on treatment for mental health problems than on treatment for physical problems, including doctor visits and hospital stays. It would also disallow higher co-payments. The insurance industry is up in arms, as are others who envision sharply higher premiums and a free-for-all over claims for coverage of things like jet lag and caffeine addiction. Parity raises all sorts of tricky questions. Is an ailment a legitimate disease if you can’t test for it? A culture tells the doctor the patient has strep throat. But if a patient says, ‘‘Doctor, I feel hopeless,’’ is that enough to justify a diagnosis of depression and health benefits to pay for treatment? How many therapy sessions are enough? If mental illness never ends, which is typically the case, how do you set a standard for coverage equal to that for physical ailments, many of which do end?
