医 (yī): Medicine, medical treatment, doctor. This character signifies the “medical” part of the term.
疗 (liáo): To treat or to cure. The sickness radical (疒) on the left indicates it's related to illness. Together, 医疗 (yīliáo) means “medical treatment.”
保 (bǎo): To protect, to guarantee, or to insure. The character originally depicted a person protecting a child, giving a strong sense of security and safety.
险 (xiǎn): Risk, danger, or peril. This character shows the “risk” that is being insured against. Together, 保险 (bǎoxiǎn) means “insurance” (literally “to insure against risk”).
When combined, 医疗保险 (yīliáo bǎoxiǎn) literally translates to “medical treatment risk-protection,” a very logical construction for the concept of health insurance.
In China, 医疗保险 is a cornerstone of the social safety net and a frequent topic of public and private discussion. Its significance is best understood by contrasting it with the pre-reform era and the common American system.
Shift from State-Guaranteed to a Hybrid System: Before the economic reforms of the 1980s and 90s, urban workers enjoyed cradle-to-grave care from their state-owned work units (单位, dānwèi), a system known as the “iron rice bowl.” Healthcare was effectively free. The modern 医疗保险 system was established to replace this, creating a multi-layered structure funded by employees, employers, and the government.
Contrast with the U.S. System: While the U.S. system is dominated by private, employer-sponsored insurance plans with varying levels of government involvement (Medicare/Medicaid), China's system is built on a foundation of mandatory public insurance (called 基本医疗保险, jīběn yīliáo bǎoxiǎn, or “basic medical insurance”). This is a key part of the national social insurance scheme (社会保险, shèhuì bǎoxiǎn). This reflects a societal value that the government has a fundamental responsibility to provide a basic level of healthcare security for all citizens, aiming for social stability. Private insurance (商业医疗保险, shāngyè yīliáo bǎoxiǎn) exists as a supplement, not the primary option for most people.
This foundational public system means the average Chinese citizen's first thought about insurance is tied to the government and their employer's legal obligations, a different starting point from the market-driven choices often faced by Americans.
