Rule 11-409 Offers to pay medical and similar expenses.

If someone pays for another person's medical bills, or offers to pay them, after an accident or injury, that fact cannot be used in court as proof that they caused the injury. For example, if a driver offers to cover the other person's hospital bills after a car accident, that offer cannot later be used as evidence that the driver was at fault.

This rule exists because people often help others out of kindness or concern, not because they're admitting blame. Courts don't want to discourage people from helping injured parties by punishing them for it later. So if you pay someone's medical costs after they get hurt, that act alone won't be held against you as an admission of guilt in a lawsuit.

It's worth noting that this rule only blocks the evidence for the purpose of proving fault. If there's some other reason to bring up the payment, like showing it happened at all for a different legal question, a court might allow it for that separate purpose.
