When Insurance Is Most Likely to Cover a CGM
Insurance providers are more likely to cover a CGM if certain conditions are met. The most common requirements include:
- You use insulin (daily or multiple times per day)
- You have frequent low or high blood sugar episodes
- Your doctor documents that a CGM is medically necessary
Medicare Coverage for CGMs
Medicare now covers CGMs for a broader group of people with diabetes, including some individuals with type 2 diabetes who do not use insulin. Coverage typically falls under durable medical equipment (DME) and requires a prescription from a healthcare provider.
