Coordination of Benefits

Example

“Due to coordination of benefits rules, my spouse's insurance paid 80% of the hospital bill as the primary coverage, and my insurance covered the remaining 20% as secondary coverage.”

Memory Tip

COB = 'Cooperation Of Both' insurances - they work together so you don't get paid more than 100% of your medical bills.

Why It Matters

Understanding coordination of benefits helps you maximize your healthcare coverage when you have multiple insurance policies, such as through both spouses' employers. It ensures you receive appropriate benefits while preventing insurance fraud, and helps you understand why claims might take longer to process or pay less than expected.

Common Misconception

Many people believe having two insurance policies means they'll receive double payments or that all their medical expenses will be fully covered. In reality, coordination of benefits ensures you never receive more than 100% of actual expenses, and you may still have out-of-pocket costs depending on each policy's terms and deductibles.

In Practice

Sarah has surgery costing $10,000. Her primary insurance (through her job) covers 80% after a $1,000 deductible, paying $7,200. Her secondary insurance (through her spouse's job) covers the remaining $1,800 after coordination of benefits, rather than paying its normal 70% of the full bill. Sarah pays only the $1,000 primary deductible, saving $1,800 compared to having just one policy.

Etymology

From Latin coordinare meaning 'to arrange in order' and benefitium meaning 'good deed,' reflecting the systematic arrangement of insurance payments to provide appropriate benefits.
