Policy note: Non-preferred agent on Illinois Medicaid PDL. Preferred agents are Trulicity (dulaglutide), Victoza (liraglutide), and liraglutide (generic) — all Step 4. Mounjaro requires step therapy through preferred injectable GLP1-RAs. Step therapy requires trial of BOTH Trulicity AND (Victoza OR liraglutide) unless intolerance/contraindication documented. Obesity alone or secondary to another condition is explicitly excluded per IL Medicaid policy. Initial approval is 30-day supplies for 6 months; renewal is 30-day supplies for 12 months. Table 1 referenced for age-appropriateness and cardiovascular/CKD benefit verification but not reproduced in this document. Note: Mounjaro's cardiovascular and CKD benefits per Table 1 are referenced but not confirmed in document text; reviewer should verify Table 1 includes Mounjaro for these pathways.

Why Mounjaro requests get denied by Illinois Medicaid

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.
  2. No documented metformin trial (dose, dates, and outcome) or a stated reason it can't be used.
  3. Required prior medication trials not documented.
