What is one of the necessary pieces of information for verifying insurance benefits?

The proposed date of service is critical for verifying insurance benefits because insurance coverage can change based on the timing of the service. Insurers often have specific policies and coverage limits that apply to certain time frames, which can affect whether a service is covered at all. Additionally, pre-authorization requirements may vary depending on the date as well. For instance, a service may be covered if rendered on a certain date, but changes in policy terms could result in a lack of coverage if the service is provided after a new policy is enacted. Therefore, having the proposed date of service is essential for accurately determining the benefits available to the patient under their current insurance plan.

Other factors such as a patient's employment history, travel history, or a doctor's fee schedule may be relevant in other contexts, but they do not hold the same direct significance in confirming what specific benefits will be available for a proposed medical service on a given date.
