In Taiwan, I pay for Universal Healthcare because I own a business. 5800nt(185usd) every 2 months for a familyof 4. It would be 3000nt(100usd)for 2 months if it's just myself.
The copay is 10usd for everything. Fever? Food poisoning? Chemotherapy? All the same cost. This includes all the medications and all incidental costs.
If you worked for a Taiwan company, you don't have to pay the 5800nt. But the copay is the same.
