Two Dexcom Stelo sensors a month, in-app dietitian chat.
FreeStyle Libre 3 Plus Details
Now sold as the FreeStyle Libre 3 Plus: Abbott's US product page describes only the Plus, and the original 14-day Libre 3 is gone, so accuracy figures published for that earlier sensor do not carry over. Abbott publishes no cash price, so none is listed here. Abbott's only published figures are that most covered patients pay $0-$20, and that commercially insured or uninsured patients asked to pay over $75 for two sensors should use the copay card - an effective ceiling near $900/year for eligible patients. The copay card excludes Medicare, Medicaid and other federal or state programme beneficiaries. Supply is two 15-day sensors per 30-day pharmacy fill. Water resistant to 1 metre for up to 30 minutes, notably weaker than several competitors.
