What is copayment? Understanding cost-sharing in AIA health insurance
What is copayment (copay)?
Copayment or copay means the insured shares part of the medical bill with the insurer. In simple terms, the insurer pays most of the cost but you pay a percentage that has been agreed. For example, if the bill is 100,000 THB and the copay is 20%, you pay 20,000 THB and the insurer pays 80,000 THB.
Why copayment exists in health insurance
Copayment is used to help control healthcare costs, reduce overuse of medical services, keep premiums at a reasonable level and keep the health insurance system sustainable. In many countries, copay is a common feature in health insurance.
Copayment in AIA health insurance
In AIA health insurance, copayment terms depend on the plan chosen, the applicant’s health history and underwriting conditions. In some cases, copay may be applied for certain health histories or when applying at higher ages. The details are clearly stated in the policy document.
How copayment affects you
Having copayment means that when you receive treatment you must pay part of the bill yourself each time. However, copay can also be positive: it can make it possible to get coverage even with some health conditions, and it can help keep premiums more affordable, increasing access to protection.
Example of a copayment situation
For example, if your copay is 30% and the total hospital bill is 200,000 THB, you would pay 60,000 THB and the insurer would pay 140,000 THB. Understanding numbers like this helps you plan your finances better when you actually need treatment.
Should you choose a plan with copayment?
Whether to choose a plan with or without copayment depends on your premium budget, current health and desired coverage level. Some people prefer plans without copay so they don’t pay extra at claim time, while in other cases a plan with copay may be the option that makes coverage affordable or even possible.
Summary and advice
Copayment or cost‑sharing is an important condition in health insurance that you should understand before buying, especially in AIA health plans where copay may apply based on underwriting. Knowing how it works helps you choose coverage that fits both your needs and your finances. If you are unsure, talk to a qualified advisor before you decide.
