Placing an order for the first time?
1. Getting started
DexCom can help guide you through the insurance and authorization process. Each insurance company and unique plan has their own set of requirements to approve your DexCom SEVEN PLUS.
DexCom has a team of experts who will help guide you through this process to help you get your DexCom SEVEN PLUS approved by your insurance company.
2. Complete these forms
In order to start the process, please download and complete the Getting Started Forms
Once you have completed these forms, please fax them, along with a copy of your insurance card (front and back), to DexCom's Sales Support Team. Note that one of the forms requires a doctor's signature.
Fax number: 1-877-633-9266.
DexCom will begin a benefits investigation with your insurance and then let you know your plan's specific coverage for the DexCom SEVEN PLUS.
