Overlap (Insurance)

A situation where two or more insurance policies provide coverage for the same risk, loss, or property. When overlap occurs, the policies typically contain coordination provisions to determine how claims will be paid and prevent duplicate payments for the same loss.

Example

“When Maria was injured in a car accident, there was overlap between her auto insurance personal injury protection and her health insurance, so the policies had to coordinate benefits to avoid double payment.”

Memory Tip

Picture two overlapping circles - where they overlap, you have double coverage that needs to be sorted out.

Why It Matters

Understanding insurance overlap helps consumers avoid paying for unnecessary duplicate coverage while ensuring they have adequate protection. It also helps in claims situations where multiple policies might apply, preventing delays and confusion about which insurer pays what portion.

Common Misconception

Many people think having overlapping insurance means they'll receive double payments for losses, but coordination provisions prevent this and may actually complicate claims processing. Others believe overlap is always bad, but sometimes it provides valuable additional protection or fills coverage gaps.

In Practice

Tom has health insurance through his employer ($500 deductible, 80/20 coinsurance) and also maintains coverage under his wife's plan ($1,000 deductible, 90/10 coinsurance). When he has surgery costing $10,000, his employer plan pays as primary: he pays $500 deductible plus 20% of remaining $9,500 ($1,900), totaling $2,400 out-of-pocket. His wife's plan then covers his remaining $2,400 as secondary coverage (minus their $1,000 deductible), paying $1,400. Tom's final out-of-pocket cost is $1,000 instead of $2,400, demonstrating how overlap can benefit the insured when properly coordinated.

Etymology

From the literal meaning of 'overlap' where one thing extends over and covers part of another, first used in insurance contexts in the early 20th century.
