Travel Insurance Terms Explained: A to Z for US Visitors

Travel insurance terms explained simply: the deductible is what you pay first, coinsurance is the share you pay next, and the policy maximum is the most the plan will ever pay. Almost every other term on a visitor insurance certificate describes what counts as covered, which doctors to use, or how to get a bill paid. This guide defines the terms that decide real money on a US trip, grouped by theme and listed alphabetically within each group, with a plain example for each.

Key facts at a glance

• Three terms drive most of what you pay at a US hospital: deductible, coinsurance and policy maximum.
• Acute onset of a pre-existing condition is a narrow emergency benefit, not general coverage for a known condition. IMG and WorldTrips wording requires treatment within 24 hours of the sudden episode.
• Age limits on acute onset differ by carrier: under 70 on IMG Patriot plans and under 80 on WorldTrips Atlas plans, according to their plan documents.
• Skipping precertification can cut benefits. Plan details for several visitor plans describe a 50% reduction for treatment that was not precertified.
• Comprehensive and fixed benefit are the two plan types; the same $20,000 bill can produce very different payments under each.

What do the cost terms mean?

• Coinsurance. The percentage split between you and the plan after the deductible. Example: Safe Travels USA Cost Saver pays 80% of the first $5,000 of eligible expenses and 100% after that, so on a $5,000 eligible bill beyond the deductible you would pay $1,000.
• Copayment. A flat amount for a specific service. Example: WorldTrips lists a $15 copayment per urgent care visit in the US under Atlas Travel.
• Deductible. The amount you pay toward covered bills before the plan pays anything. Example: with a $250 deductible and a $1,400 clinic bill, you pay the first $250 and the plan assesses the remaining $1,150. See how to choose a deductible and policy maximum.
• Policy maximum. The ceiling on what the plan pays in total during the policy period. Example: on a $100,000 maximum, a $130,000 hospital stay leaves $30,000 to you even with every charge eligible.
• Premium. The price of the policy. It depends on age, number of days, policy maximum and deductible. Example: a higher deductible generally lowers it.

What do the coverage terms mean?

• Acute onset of a pre-existing condition. A sudden, unexpected flare of an existing condition that needs urgent care, with treatment obtained within 24 hours. Example: a visitor with controlled blood pressure who has a sudden stroke may qualify; a refill or scheduled checkup does not. Read the acute onset explainer.
• Comprehensive plan. A plan that pays a percentage of eligible charges up to the policy maximum. Example: Atlas America pays 100% of eligible expenses after the deductible, according to its plan details.
• Exclusion. Something the plan never pays for. Example: routine physicals and vaccinations are commonly excluded on visitor plans.
• Fixed benefit plan. Also called a limited plan. It pays a set dollar amount per service regardless of the bill. Example: if the schedule allows a fixed amount per hospital day and the hospital charges several times that, you owe the difference.
• Medically necessary. Care that is appropriate for diagnosing or treating a condition under accepted medical standards. Example: an imaging scan ordered for a suspected fracture qualifies; a scan requested for reassurance may not.
• Pre-existing condition. Any illness or injury that existed, showed symptoms or was treated before the policy started, usually within a stated lookback period. Example: diabetes diagnosed years ago is pre-existing even if it is well managed.
• Usual, reasonable and customary (URC or UCR). The amount the insurer considers a normal charge for a service in that area. Example: if a clinic bills $900 and the insurer's customary amount is $600, an out of network patient can be billed the $300 gap.

What do the network and billing terms mean?

• Direct billing. The provider sends the bill to the insurer instead of asking you to pay in full. Example: a network hospital verifies your ID card and bills the administrator, and you pay only your deductible share later.
• Guarantee of payment. A letter from the administrator telling a hospital that eligible charges will be paid, often needed before a planned admission. Example: the billing office requests it during admission.
• Out of network. A provider with no contract with the plan's network. Example: Patriot Plus pays 100% in network but 90% of the first $5,000 out of network, according to its plan details.
• PPO network. A group of doctors and hospitals that accept negotiated rates. Example: Atlas America and Patriot Plus use the UnitedHealthcare network, and Visitors Care uses First Health. See direct billing and PPO networks.
• Precertification. Notifying the administrator before a hospital admission, surgery or other listed service. Example: a relative calls the number on the ID card the day a visitor is admitted so benefits are not reduced.
• Urgent care. A walk in clinic for problems that need same day attention but are not emergencies. Example: a sprained ankle or a fever is an urgent care visit, usually at a fraction of an emergency room bill.

What do evacuation and repatriation mean?

• Emergency medical evacuation. Transport to the nearest facility able to treat you when local care is inadequate, arranged and approved by the insurer. Example: Atlas America lists up to $1,000,000 for this benefit and Visitors Care lists up to $25,000. Details in our evacuation coverage guide.
• Home country. The country where you have your permanent residence, which is where coverage normally ends. Example: a visitor's Atlas Travel coverage terminates on return home, according to WorldTrips wording.
• Repatriation of remains. The cost of returning a deceased traveler to the home country, or local cremation or burial. Example: the family contacts the administrator, which coordinates with a funeral provider and pays up to the stated limit.
• Return of minor children and emergency reunion. Benefits that pay to send unattended children home or to bring a relative to a hospitalized traveler. Example: an adult child flies in to stay with a parent in intensive care.

What do the timing and document terms mean?

• Certificate of insurance. The document that sets out your actual coverage. Example: when a brochure and the certificate differ, the certificate controls.
• Effective date. The moment coverage starts. Example: under Atlas Travel it is the latest of when the application is received, when you leave your home country, and the date you requested.
• Extension or renewal. Adding days to a policy before it ends. Example: plan details for most visitor plans allow extensions up to 364 or 365 days in total, often for a $5 fee.
• Lookback period. How far back the insurer reviews medical history to decide whether a condition is pre-existing. Example: a doctor visit for chest pain two months before the trip can make a later cardiac claim pre-existing.
• Visa letter. A letter confirming your coverage details, used for visa applications. Example: Schengen consulates ask for proof of at least EUR 30,000 in medical coverage; US B-2 applications have no insurance requirement.

What do the claim terms mean?

• Claim form. The claimant's statement that starts a reimbursement. Example: you complete it, attach the bills and records, and send it to the administrator named on your ID card.
• Explanation of benefits (EOB). The insurer's statement showing what was billed, what was allowed, what was paid and what you owe. Example: compare the EOB with the provider's bill before paying a balance.
• Itemized bill. A bill listing each service with its code and charge. Example: a credit card receipt that only shows a total is not enough to process a claim.
• Timely filing. The deadline for sending a claim after treatment. Example: a claim sent after the deadline in the certificate can be refused even if the care was covered.

How to get covered once you know the terms

Open the visitor insurance quote page and enter the traveler's age, home country and dates. Each result shows the plan type, deductible options, policy maximum, network and acute onset terms, which are the same words defined above.

Premiums depend on age, trip length, policy maximum and deductible, so compare live quotes rather than assuming a price. Which plans appear depends on the traveler's home country, because some plans cannot be sold to residents of certain countries.

Frequently Asked Questions

What is the difference between a deductible and coinsurance?

The deductible is a fixed dollar amount you pay first. Coinsurance is a percentage you pay after the deductible has been met, usually only on the first few thousand dollars of charges. On a plan with a $250 deductible that then pays 80% of the next $5,000, a $5,250 eligible bill would cost you $250 plus $1,000.

Is acute onset the same as covering pre-existing conditions?

No. Acute onset pays only for a sudden, unexpected emergency caused by an existing condition, and only when treatment is sought quickly, within 24 hours under IMG and WorldTrips wording. It does not pay for medication, monitoring, scheduled treatment or a condition that worsens gradually. Age limits apply, and some plans cap the amount well below the policy maximum.

What does PPO mean on a visitor insurance plan?

PPO stands for preferred provider organization, a network of doctors and hospitals that have agreed to negotiated rates. Using a network provider usually means lower charges and a better chance of direct billing. You can normally still see providers outside the network, but the plan may pay a smaller share and you can be billed for amounts above the customary charge.

What does repatriation mean in travel insurance?

Repatriation of remains is the benefit that pays to return a deceased traveler's body to the home country, or for local burial or cremation, up to a stated limit. It is separate from emergency medical evacuation, which moves a living patient to a hospital that can treat them. Both must be arranged through the plan administrator to be paid.
