Travelling to the United States with Cancer: Managing the World's Highest Medical Costs

The United States offers some of the world's most advanced medical facilities, including leading cancer centres like MD Anderson, Memorial Sloan Kettering, and the Mayo Clinic. But visiting as an uninsured or underinsured cancer patient exposes you to a level of financial risk that is genuinely unique in the world. A single hospital admission for a cancer-related complication — something as common as an infection, a pulmonary embolism, or an allergic reaction to contrast dye during imaging — can result in a bill that exceeds the cost of your entire oncology treatment back home.

Understanding the risk, getting the right cover, and planning carefully are the three pillars of travelling to the USA with cancer.

Medical Facilities and Healthcare Access

American hospitals range from extraordinary to ordinary. The top-tier academic medical centres — MD Anderson in Houston, Memorial Sloan Kettering in New York, Mayo Clinic in Rochester and Scottsdale, Johns Hopkins in Baltimore, Dana-Farber in Boston — are genuinely among the best in the world for cancer care. Most major cities have large teaching hospitals with excellent oncology departments.

However, unlike in Australia or the UK, there is no public healthcare system that visitors can access. Every aspect of US hospital care — from the emergency department consultation to the IV line to the antibiotic — is billed separately and at rates that are not negotiated down for uninsured international visitors. The billing system is complex, opaque, and designed for a domestic insurance market that does not apply to you.

There is no reciprocal healthcare agreement between this country and the United States. You are entirely dependent on your travel insurance.

Key Risks for Cancer Patients

Catastrophic Cost Exposure

This is not hyperbole. A three-day hospital stay in a US hospital for a cancer complication — say, febrile neutropenia requiring IV antibiotics and monitoring — can generate a bill of NZ$80,000 to NZ$200,000. An ICU admission for a more serious complication such as sepsis, a pulmonary embolism, or a treatment-related cardiac event can exceed NZ$500,000. A medical evacuation from a US city back home by air ambulance adds NZ$80,000 to NZ$200,000 to that figure.

These are not theoretical figures — they reflect real costs in a system where hospital list prices for international patients are not subject to the negotiated rates that domestic insurers receive.

The Unlimited Cover Imperative

Many travel insurance policies sold in this market have medical expense caps — NZ$2 million, NZ$5 million, NZ$10 million. For most destinations, these caps are more than adequate. For the United States, with a complex cancer complication, even a NZ$5 million cap could be consumed by a prolonged ICU admission. For travel to the USA with a cancer diagnosis, you should seek a policy with unlimited medical cover, or the highest cap available from a specialist insurer.

DVT on Long-Haul Flights

The flight from Auckland to Los Angeles or San Francisco is approximately 12 to 13 hours. To New York via a connection, total travel time is typically 18 to 24 hours. Cancer significantly increases clotting risk — some estimates put the relative risk 4 to 7 times higher than the general population, and this is compounded by prolonged immobility in an aircraft cabin. Before booking, discuss DVT prophylaxis with your oncologist. Compression stockings are a minimum; some patients are prescribed low-molecular-weight heparin injections for long-haul flights.

ESTA and Visa Considerations

Most travellers enter the USA on the ESTA Visa Waiver Program. ESTA requires disclosure of medical conditions in some circumstances — specifically communicable diseases. Cancer is not a communicable disease and does not typically affect ESTA eligibility. However, if you are visiting for medical purposes, you may technically be considered a "medical visitor" — this is a nuance worth reviewing, and if in doubt, consulting with a US immigration attorney before travel is worthwhile. Your travel insurance requirements are unaffected by visa type.

Medication Management

Many cancer medications are available in the USA but require a US prescription. If you need an emergency refill or a replacement for lost medication, you will generally need to see a US physician first. Keep comprehensive documentation of your medications — generic name, brand name, dose, prescribing oncologist's details — and carry more supply than you need. Some oncology pharmacies in major cities can assist international patients in genuine emergencies.

What Your Travel Insurance Must Cover

For the United States specifically, your policy must include:

• Unlimited medical expenses (or the highest available limit — do not accept a cap below NZ$10 million)
• Medical evacuation and repatriation with no sub-limit — the cost of flying you home from the US in a medical emergency is high
• Cancer as a declared and covered pre-existing condition — verified in writing before departure
• Cancellation and curtailment at a level that covers the full cost of your US booking (flights, accommodation, tours)
• 24-hour emergency assistance with a US-based or US-capable network — your insurer needs to be able to manage US hospital billing on your behalf

Timing Your Trip Around Treatment

The USA is a long way away, and that distance creates logistical challenges that Australia does not:

• If you are mid-treatment, extended time away from your oncology team requires careful coordination — can surveillance blood tests, imaging, or infusions be arranged locally in the USA if needed?
• Allow extra time for the body to recover from the flight before any physically demanding activities
• Account for significant time zone changes when scheduling medication — oral medications taken at a specific time of day need a clear plan for the transition across multiple time zones
• If you have a port or PICC line for chemotherapy, carry documentation and understand that US hospitals will need this information urgently if you present to an emergency department

Tips for Getting the Best Cover

1. Do not compromise on the medical limit. The single most important variable for USA travel insurance is the medical expense limit. Unlimited is the gold standard.

2. Use a specialist cancer travel insurance broker rather than booking a general policy online. The policy wording for pre-existing condition cover is complex, and specialist brokers can match you to the right product.

3. Get the cancer covered in writing. Before you travel, obtain written confirmation from your insurer that your specific cancer type, stage, and current treatment is covered. Not just disclosed — covered.

4. Carry a full medication list in both generic and brand names, along with your oncologist's contact details, your diagnosis summary, and your treatment history.

5. Register with your embassy. Register your travel with the New Zealand Ministry of Foreign Affairs and Trade (MFAT) SafeTravel so that in a crisis, consular assistance can be coordinated.

6. Don't delay getting a quote. The earlier you get cover in place relative to your trip deposit, the more complete your cancellation cover will be.
