A Medicare Supplement (Medigap) policy is health insurance sold by private insurance companies to fill the gaps in Original Medicare Plan coverage. Medigap policies help pay some of the health care costs that the Original Medicare Plan doesn't cover.
Internal Medicine encompasses the care of all adults, healthy and sick. Internists (as all doctors who complete an internal medicine residency are called) can be generalists or subspecialists, like cardiologists or rheumatologists. If you choose not to subspecialize, you are known as a General Internist.
Overview. Doctors of internal medicine, called internists focus on comprehensive adult medicine. While the name internal medicine may lead one to believe that internists only treat internal problems, this is not the case. Doctors of internal medicine treat the whole person, not just internal organs.
