Why Mounjaro requests get denied by Aetna

Based on what this policy asks for. Fix these before the first submission.

  1. Wrong brand for the diagnosis. Mounjaro and Zepbound are the same molecule with different approved uses; a request for Mounjaro under a diagnosis that matches Zepbound is routinely denied.
