What is What Is Coordination of Benefits?
Coordination of benefits (COB) rules determine which health plan pays first when a person is covered by two policies — typically an employee's own plan is primary over a spouse's.
Practical Example
When a U.S. consumer researches coordination of benefits, understanding the mechanics up front helps them compare providers, avoid hidden fees and choose the option that best fits their budget and long-term goals.
Why It Matters
Getting coordination of benefits right can save households hundreds to thousands of dollars each year and prevents disputes that end up in state regulator complaints or court.
