I think time will comes that every sector will accept bitcoin, since bitcoin is not yet fully known in every country it needs more advertisement and promotion to make it more popular, also government should accept it first to have support to implement bitcoin as mode of payment
Well in some countries they are not fully into crypto currency and very few are using bitcoin as their currency because of its volatility in price, It is hard to think that it can be use in some medical billing program or institutions because of its demand nowadays, Most of people are not familiar with blockchain and crypto currency.
