How many days before providing information to the evaluator must a party serve that information on the opposing party?

The requirement for serving information to the opposing party before providing it to the evaluator is set to ensure that both parties have a fair chance to review and respond to the information being presented. According to the regulations governing the Qualified Medical Evaluator process, a party must serve the opposing party with any information they intend to present to the evaluator at least 20 days in advance. This timeline promotes transparency and allows adequate time for the opposing party to prepare their arguments or counterarguments, contributing to a more equitable evaluation process.

The other options do not satisfy the minimum advance notice required by the regulations, making them unsuitable for ensuring fairness and thorough preparation in the evaluation process. Hence, the correct answer is based on adherence to established guidelines aimed at maintaining procedural integrity.
