Is the Era of 100% Full-Coverage Health Insurance Ending? When Giants AIA and Krungthai-Axa Close the Chapter on Popular Health Plans

This movement is shaking both the insurance business sector and consumers as two market giants simultaneously signal the discontinuation of their flagship products around the same time.

Starting with Krungthai-Axa Life Insurance, which announced it will stop selling the popular critical illness plan iCare (covering 5 major illnesses) on 31 Jan 2026, after more than 12 years on the market, citing rising critical illness incidence rates that no longer align with the old premium pricing.

Recently, AIA Thailand, the market leader, also declared it will end sales of AIA Health Happy, a full-coverage health insurance plan (with coverage up to 25 million baht) that has long been popular, with sales ending on 31 Mar 2026 as well.

The moves by these two "market leaders" are no coincidence but represent a significant inflection point in Thailand's health insurance system, signaling that the era of "100% unconditional full-coverage health insurance" may be coming to an end.

Why is the industry retreating?

Analyzing the communications from these two major players from a business perspective, the discontinuation of these products is a "portfolio rebalancing" effort aimed at long-term survival amid three pressing factors.

1. Medical Inflation: Medical expenses in Thailand have surged beyond the predictions of statistical models from 5-10 years ago. Treatments using new technologies cause the full-coverage limits in the tens of millions to be utilized more frequently and faster. According to data from the Office of Insurance Commission (OIC), the regulatory body overseeing insurance, medical inflation rose approximately 15% in 2024.
2. Uncontrollable Loss Ratios: Changes in insured behavior toward "hospital stays for convenience" or over-treatment have forced companies to bear higher claim costs that could threaten their financial stability in the long run.
3. Aging Society: As Thai people live longer but suffer chronic illnesses longer, the healthcare system's burden shifts from just curing illnesses to ongoing management, requiring massive resources.

The business must survive, and consumers must remain protected.

From a business standpoint, the shift to co-payment systems or introducing deductibles, which began around 2025, aims to instill "discipline in benefit usage" to sustain the insurance system and ensure insurers remain profitable enough to pay claims for genuinely severe cases in the future.

After Arpakorn Panlert, Deputy Secretary-General for Insurance Business Regulation at the OIC, revealed that by the end of 2024, inappropriate use of benefits accounted for 28% of the loss ratio, despite only 5% of all policies’ holders utilizing benefits.

From the consumer perspective, this signals the unavoidable "costly era" ahead. Health insurance will have more complex conditions; premiums may initially seem lower but include co-payments, or if one wants full coverage as before, premiums will rise significantly, potentially becoming a heavy burden during retirement.

Who should bear responsibility in the new era of healthcare?

According to the OIC, total insurance premiums in 2026 may reach 1,000 billion baht, reflecting increased public awareness about transferring health risks to insurance. However, a key question remains: who will primarily bear the healthcare system's burden?

The future answer may not rest solely with insurance companies but rather a shared responsibility model.

• Insurance companies: must design products focusing more on preventive care rather than just claims.
• Consumers: need to maintain their health to reduce claims and accept co-payment conditions to keep premiums manageable.
• Insurance agents: must shift roles from "salespeople" to "health financial advisors" helping clients plan for rising premiums due to aging and advancing technologies.

How should consumers prepare?

1. Check-up: If you currently hold Health Happy or iCare policies, "do not let them lapse" as these are valuable assets granting you rights under existing conditions as long as you renew.
2. The Last Call: For those without full-coverage insurance, the period before March 2026 is the final opportunity to "lock in" favorable terms while companies still offer them.
3. Plan for long-term premiums: Look beyond the first-year premium and consider premiums at ages 60-70. If conditions tighten or premiums rise, ensure you have sufficient cash flow to manage.

This discontinuation signals the end of the golden age of "buffet-style" insurance and the full arrival of the era where "health setbacks require co-payments."
