美國對認定非法行醫的例外有下列情況：

Exceptions

There are some actions that are specifically excluded from the crime of practicing medicine without a license. For example, applying home remedies, offering advice, and writing about nutrition or medical conditions are not considered practicing medicine. Also, performing other types of healthcare related activities, such as acting as a pharmacist, nurse, or dentist is also not considered practicing medicine, though states also require people practicing those professions to be properly licensed.
