How Elevance Health denies continuous glucose monitors & insulin pumps — and how to counter it

Where Elevance Health pushes back: 1) 'Try MiniMed 670G or 770G before 780G'; 2) 'SmartGuard auto-bolus too aggressive'; 3) 'No clinical advantage over predicate'.

Counter-arguments that hold up: MiniMed 770G has been discontinued by Medtronic; 670G is two generations old. 780G + Guardian 4 FDA-approved Apr 21, 2023 with meal-detection auto-correction every 5 min — first AID with this feature. ADAPT (Choudhary P et al., Lancet Diabetes Endocrinol 2022;10:720-731): 1.4% A1c reduction and 27.6% TIR improvement vs MDI+isCGM at 6 months, sustained at 12 months, no DKA or severe hypo. Auto-correction is the mechanism of benefit, not a safety risk.
