Vaccinations: Excellent health facilities are available in Mexico City and other major cities, but training and availability of emergency responders may be below U.S. standards. Mexican facilities often require payment “up front” prior to performing a procedure, and most hospitals in Mexico do not accept U.S. health insurance. A list of doctors and hospitals is available on the U.S. Embassy or Consulate website.
U.S. citizens have lodged numerous complaints against some private hospitals in Cancun, the Riviera Maya, and Cabo San Lucas to include exorbitant prices and inflexible collection measures. Travelers should obtain complete information on billing, pricing, and proposed medical procedures before agreeing to any medical care in these locations. Be aware that some resorts have exclusive agreements with medical providers, which may limit your choices in seeking emergency medical attention.
We do not pay medical bills. Be aware that U.S. Medicare does not apply overseas.
Medical Insurance: Make sure your health insurance plan provides coverage overseas. Most care providers overseas only accept cash payments. See the Your Health Abroad page for more information on overseas medical care.
We strongly recommend supplemental insurance (our webpage) to cover medical evacuation.
Water Quality: In many areas in Mexico, tap water is not potable. Bottled water and beverages are safe, although you should be aware that many restaurants and hotels serve tap water unless bottled water is specifically requested. Be aware that ice for drinks may be made using tap water.
