  == 20% subsidy ==   In addition, NKFS gives patients a 20 percent subsidy only. Subsidized patients, after meeting the stringent requirement of not earning more than $1,000, have to foot 80 percent of the bill.   I remove the above text, until the source is provided, I tried to find but failed. Earlier section indicates that the subsidy is about 30% on average for NKFS patients. But it would be shocking if indeed patients earning less than $1,000 still have to foot 80% of bill! Please provide sources, thank you.
