transfer the patient to a gov't hospital asap...the bill will be much less. He will remain in ICU as TB requires, once cleared he can be treated in a ward until released or ? The bills from the private and gov't hospital are the responsibility of the patient/next of kin/or anyone who signs. That was my experience a few years ago/pre-covid. The private hospital helped organize the transfer when informed the patient had limited funds early in the crisis.
