You will have to use some very grossly basic reasoning here. Hopefully you are sitting down because this will shock you.
From medicare.gov
"A doctor can be a Doctor of Medicine (MD), a Doctor of Osteopathic Medicine (DO), or, in some cases, a dentist, optometrist (eye doctor), or chiropractor. Medicare also covers services provided by
other health care providers, like physician assistants, nurse practitioners, clinical nurse specialists, clinical social workers, physical and occupational therapists, speech language pathologists, and clinical psychologists."

From wikipedia (weak source, I know but simply a definition. bear with me)
"A
health professional or
healthcare provider is an individual who provides preventive, curative, promotional or rehabilitative
health care services in a systematic way to people, families or communities."

From Cal Berkeley
"Under federal regulations, a "
health care provider" is defined as: a doctor of medicine or osteopathy, podiatrist, dentist, chiropractor, clinical psychologist, optometrist, nurse practitioner, nurse-midwife, or a clinical social worker who is authorized to practice by the State and performing within the scope of their practice as defined by State law, or a
Christian Science practitioner (lolololololololol)"

@deafdealer or anyone else that is confused about their role as healthcare providers?
