Why HealthcareWiki exists
Health insurance is notoriously confusing — full of jargon, fine print, and acronyms that make even simple decisions feel overwhelming. Most people encounter terms like deductible, out-of-pocket maximum, or EOB without any context for what they actually mean in practice.
HealthcareWiki was built to be the reference we wished existed — something that explains every term clearly, shows how concepts connect, and gives you the tools to make smarter decisions about your own coverage.
