Last week I had gall bladder removed at University Hospital in P'lok.
There are items on the bill, all in Thai, which on translation I do not understand, like 'Prothesis Organs and Medical Equipment = Bht 11,000. The actual procedure/anaesthetic is there as Bht 16,300. Medical Equipment & Tools = Bht 1650, So check it out carefully before you, or your insurance company, pay.
