Stain,
I am not sure if you understood what I was trying to say. Medical exams are often not required because the physician who certifies them from a foreign country has no license to practice in the US. However, I cannot imagine an insurance application form that does not ask for state of current health which includes pre-existing conditions before determining a person's risk for a health related 'event' in the near future.They use this to determine the premium.
The health evaluation that I was talking about was merely a suggestion that If your parents have a health evaluation from the country of origin few months prior to planned travel, they can do the following:
1. Have enough time to stabilize any uncontrolled conditions such as Diabetes, or hypertension.
2.Undergo procedures such as cardiac catheterization 9if necessary) and have interventions such as angioplasty (if indicated) prior to coming here. These procedures are very expensive in the US and are safer if done electively than emergently.Also , there is a recovery time for these procedures and hence my suggestion to have the evaluation a few months prior to proposed travel.
3.Carry enough supplies of medications with them for duration of travel. You cannot get any refills here without proper prescriptions and no doctor would give you a prescription here without a documented office visit. Obviously, the office visits are expensive and prescription drugs without coverage are too. Note that most travel insurances either don't cover these meds or have a high copay.
In my opinion, most travel insurances are of modest benefit at best and if a real emergency occurs, most insurance companies would find a way to wriggle out of payment. It is in your own interest to have your parents checked out well before they come here. Also, you might hear from a few people that you if an emergent situation occurs, you can have your parents registered as primary payer and then if they don't pay up, the hospital will absorb the cost. This is entirely untrue. When you hit the ER, you(or someone with a valid SS#) will be forced to sign as a guarantor for the whole payment and in some cases, require a credit card number and /or evidence of financial resources for the payment (in less acute situations). Also, it is worth noting that while an insurance such as medicare only pays about 30% of the billed amount, an uninsured person or if your insurance company disowns the payment after the event, a foreign born person or his/her guarantor is obligated to pay the FULL amount billed, which can be unbearably expensive.
Bottom line: The health care industry here is very unfriendly for a foreign born person. I did not write all this to scare you. I think it is better if we all have the facts straight before we decide on thge insurance companies.
I have however, heard (cannot confirm) that Kaiser offers a plan for foreign born persons who travel and have a more clear cut explanation of benefits. I heard it costs around $5000-$10,000 per person per year but coverage is better than most other companies if something happens.Good luck!!
