What You'll Actually Pay

With Insurance (Most Common)

Since Mounjaro is FDA-approved for type 2 diabetes, it typically has better insurance coverage than weight-loss-only medications like Zepbound or Wegovy.

Insurance + Lilly Savings Card	$25	$300
Insurance only (Tier 3-4)	$75-200	$900-2,400
No coverage (GoodRx)	$950-1,050	$11,400-12,600

Best Strategy for Mounjaro

If you have diabetes + commercial insurance: This is the ideal scenario. Use Mounjaro with the Lilly Savings Card for $25/month.

If you have diabetes + Medicare: Mounjaro is covered under Part D. Copays vary by plan ($50-200/month typical). Savings card NOT valid.

If you DON'T have diabetes: Mounjaro likely won't be covered. Consider Zepbound vials ($299-449/mo) or compounded tirzepatide instead.
