It can be acceptable to refuse to have medical treatment and not have it count as 'failing to mitigate loss', provided the decision is not demonstrated to be unreasonable. If a claimant refuses treatment it is up to the defendant to present sufficient evidence to demonstrate that it was unreasonable of them to refuse. In a recent case the damages awarded to a claimant were not reduced because of her refusal to have an operation on her injured back: this left her $80,000 better off.
