The hospitals make up their own rules, when I tested positive In asq on day 5 I had to test again in hospital 10 days later, luckily I tested negative and was discharged on the same day I would have left asq,my bill was 105,000 which my insurance paid, another guy in the same hospital tested positive again and had to stay 14 days in hospital until he tested negative, his bill was 231,000b
