ANSI 834 is a special way that companies send information about their employees to health insurance companies. It's like a special language that insurance companies use to understand who works for a company and what kind of health insurance they need. Imagine that the insurance company only speaks Spanish and the employer speaks English, ANSI 834 is like a bilingual person who can help them understand each other. It helps companies save time and make sure their employees get the right health insurance benefits.
