500

Dr. Smith is an OBGYN with a claims-made policy (retroactive date: 1/1/21). She delivers a baby in March 2023; the baby suffers a birth injury. In August of 2025, Dr. Smith Retires and cancels her policy WITHOUT purchasing tail coverage. In January 2026, the family filed a lawsuit. Dr. Smith’s new insurer has a retroactive date of September 2025. Which policy (if any) covers this claim?

No policy will respond, because the claim was made after the original policy ended and before the new policy’s retroactive date.

500

This coverage requirement means a claim must be reported during the active policy period, often creating the need for tail coverage upon cancellation 

Claims-made coverage 

500

This legal and structural difference explains why malpractice claims often take longer to resolve and involve more complex litigation than E&O claims 

The involvement of bodily injury and medical standards of care

500

This broad industry trend reflects increasing claim severity driven by larger settlements, rising litigation costs, and more complex legal environements.
