What is Collateral Source Rule?

Updated January 24, 2026

A legal doctrine preventing defendants from reducing damages by showing the plaintiff received compensation from other sources like health insurance.

Understanding Collateral Source Rule

The rule prevents wrongdoers from benefiting because plaintiffs had insurance or other coverage. In some states, the rule has been modified by statute. It means plaintiffs can recover medical bills even if insurance paid less than the billed amount.

Examples

  • 1Full medical bills awarded despite insurance payment
  • 2Defendant cannot mention plaintiff's disability payments
  • 3Jury not told about health insurance coverage
