Oops. Obamacare might not cover your pre-existing condition: Key to understanding this distinction is that having “health coverage” is not the same as actually obtaining “health care.” The insurance plan has to take anyone who wants to enroll, regardless of their health status or health history – but they don’t have to provide the same treatments, the same doctors, or the same medications that a patient has been receiving. For someone in the middle of a cancer treatment, or someone with a chronic condition, this can be almost equivalent to losing insurance entirely.
