In order for it to be considered a pre-existing medical condition it must fit the specific definition found in the policy and usually that requires care, treatment, or symptoms during the look back period to be considered pre-existing. If it occurs outside that period than it’s not a pre-existing condition. The look back period for most travel insurance policies can vary between 2 to 6 months. The look back period for an international medical plan is usually 1 - 3 years.
