Rule 409: Offers to Pay Medical and Similar Expenses

Rule 409 is one of the simplest evidence rules. It provides that offers or payments of medical expenses cannot be used to prove that the person paying was at fault for the injury. If someone pays another person's hospital bills after a car accident, that payment cannot be introduced as evidence that the payer caused the accident.

The humanitarian purpose behind this rule is clear: society wants to encourage people to help injured persons by covering their medical costs. Without this protection, Good Samaritans might hesitate to offer financial help for fear it would be treated as an admission of responsibility.

Importantly, Rule 409 is narrower than Rule 408. It only protects the offer or payment itself — it does not protect accompanying statements. If someone says 'I'm sorry I ran that red light — let me pay your hospital bills,' the offer to pay the bills is excluded under 409, but the admission about running the red light is still admissible. This is a crucial distinction from Rule 408, which also protects statements made during settlement negotiations.
