A friendkindly copied info about a new scheme allowing foreigners to participate in the Thai government 30 baht health project. It started in 2556.
It turns out it costs 2,200 Baht to join with an additional 600 Baht health check required at the same time. This gives one access to the Government hospital where you join the scheme, for 1 year.
My wife and I went to the Khon Kaen Central hospital, Sri Chant road, yesterday, and were guided through the process relatively painlessly.
We needed my Passport, 2 passport photos, my yellow book (Tabien bahn), and, of course, 2,800 Baht.
The initial health check went through, Height, Weight, Blood pressure, followed by Urine and Blood samples and a chest Xray.
As we went in the afternoon we had to return the next day to get the results and the card. Had we been earlier it could have been completed same day. All was well and so I am now in possession of the "Open Sesame" to the Khon khen Hospital in case of emergencies.
If you are young and well off you do not need this help, however I believe that the majority of "Farangs" are, like me, too old to get good health insurance at affordable prices, so will be very glad to have the card as a cushion against the uncertainties of old age and dry rot.
Good luck.
