I don't see any reason why you could not be able to get an insurance from your job and you should get it because whenever you have a health problems (whatever it may be) it is very costly especially without health insurance.
If no insurance and need antiviral drugs, possible to get generic brand of entecavir from India, about $700 for one year's usage, per HR.
Do you know how to get it from India? Please share if anyone has this info./exp.
