In this context, "integrated" refers to the fact that the reconsideration/appeal process is part of the overall coverage decision process. The "integrated Coverage Decision Letter" is a document that outlines the insurer's decision regarding coverage for a specific health care service or treatment. The "integrated reconsideration" is an opportunity to request a review of that decision within a set timeframe. Therefore, "integrated" means that the reconsideration process is an integral part of the overall decision-making process. I think "یکپارچه" can convey this meaning.
