Taiwan's national health insurance system is well known in the world for its unparalleled quality and services. It allows equal access to healthcare for all citizens. Even the economically disadvantaged enjoy comprehensive coverage and need not worry about unaffordable medical bills. However, national health insurance budget constraints limit the scope of medical services that can be made available to patients. For example, if a patient is diagnosed as requiring rehabilitation or physical therapy, the national health insurance system covers up to six follow-up therapy sessions with only an NT$50 self-payment for each session. Due to limited resources, each therapy session may be short and ineffective in relieving the patient's affliction amid the lack of a tailored one-on-one care plan. Patients therefore end up seeking self-pay treatment solutions
