Most people visiting the US, especially parents and grandparents, have some health history: blood pressure, diabetes, a heart stent, asthma. The first question families ask us at Protect Travel is whether visitor insurance will cover it.
The short answer: no visitor plan pays for the ongoing care of a known condition, but some plans pay for a sudden, unexpected flare-up. That is called "acute onset of a pre-existing condition".
What counts as pre-existing
Each plan looks back over a set period before the start date. A condition that existed in that time usually counts as pre-existing, whether or not it was diagnosed or treated. Ongoing, chronic or congenital conditions fall under the exclusion.
What "acute onset" means
In general, acute onset is a sudden and unexpected flare-up that comes on quickly, gets worse fast and needs urgent care. A condition that slowly gets worse over time isn't acute onset.
Plans that include this cover set their own rules, for example about timing and how quickly treatment starts. It usually doesn't apply if the visitor traveled against a doctor's advice or traveled to get treatment. Terms, conditions, limitations and exclusions apply.
How plans differ
- Not every plan includes acute onset cover.
- Where it is included, the limits differ by plan and often by age, and can be lower for older visitors.
- Some plans also limit specific kinds of treatment, such as heart-related care.
If an older parent has a known condition, the plan choice matters more than the price difference. Compare our visitor medical plans and read each plan's details before you buy.
What no visitor plan covers
- Routine check-ups and monitoring of a known condition
- Regular prescriptions and refills
- Planned treatment, tests or surgery
- Anything the visitor traveled to get treated
- A condition that gets worse gradually rather than suddenly
Bring enough regular medicine for the whole stay, and a list of medicines and diagnoses in English.
Do they have to answer health questions?
Visitor plans generally don't involve a medical exam. Instead, the pre-existing condition rules apply when there's a claim, and the insurer can ask for medical records from before the trip. Be honest about health history if asked.
Tips that help a claim
- Buy before arrival, so cover starts the day they land.
- Call the assistance number on the ID card before a planned hospital stay or surgery.
- Get treated promptly when something sudden happens.
- Don't let it lapse. If the visit gets longer, extend before the end date.
