Discrimination in health-care coverage

Birth control methods that don't require a prescription (such as condoms and spermicides) are now easy to obtain, but we pay for them ourselves.  On the other hand, birth control methods for which one needs a prescription, which are almost always methods used by women (for example, birth-control pills, diaphragms, and intrauterine devices), are political footballs--liberals want insurance to pay for them, while conservatives won't touch them with a ten-foot pole.  So we pay even more for them ourselves.  Or else, we end up seeking abortions because we couldn't afford to prevent the conceptions.  For so-call pro-life advocates, that might be described as a case of penny-wise and fetus-foolish.  :(

But what about the rest of health care?  Why is it that the mouth is covered, but the teeth are not--we need separate dental insurance; that the eyes are covered, but glasses are not--we need separate insurance to pay for glasses; that the ears are covered, but hearing aids are not--good luck even finding insurance that pays for hearing aids!; that the legs are covered, but wheelchairs are covered by insurance for in-house use only, as if a person with mobility challenges is forbidden ever to go outside?  Aren't all of our parts part of our whole?  Why does health-care coverage discriminate against full-body health, safety, and well-being?

Much of this is nothing new, unfortunately.
