A policy covers financial losses from trip cancellation, medical emergencies abroad, lost luggage, and related disruptions. That policy is travel insurance. It transfers certain risks from the traveler to an insurer.

Coverage scope and exclusions vary widely; reading the policy is essential. Pre-existing medical conditions, high-risk activities, and travel against official advice often limit claims. Purchase timing can affect eligibility for cancellation cover for medical reasons.

Medical coverage is especially important for destinations where care is costly or where reciprocal health agreements do not apply. Assistance services that arrange care and evacuation add practical value beyond pure reimbursement. For many trips the premium is modest relative to the potential costs of an uncovered incident.

Travel insurance is unused paperwork until the day it becomes the most important document in the bag.
