Another important and often overlooked element of international health insurance policies is the underwriting criteria used by the insurance provider. Policies are underwritten in one of two ways: moratorium; and full medical underwriting. With moratorium underwriting, applicants are not required to disclose any medical declarations, and so some pre-existing conditions may be covered; although, there are restrictions to the coverage of pre-existing conditions. New or unexpected conditions occurring after the start date are covered according to policy conditions. Full medical underwriting requires the collection of a full medical history, and usually excludes coverage of pre-existing conditions.
