PAAS Tips:

  • See our March 2024 Newsline article, Continuous Glucose Monitor (CGM) Billing and Supply Allowance for additional Medicare Part B billing information
    • Use the CGM Supply Allowance Billing Calculator found on your DME MAC website to help determine when the next date of service can be billed
      • CGS
      • Noridian
    • Check out this similar tool myCGS for a complete claim history to be sure the patient has not received supplies from another supplier in the last 30 or 90 days
    • If the patient requires a replacement sensor, transmitter, or receiver due to a product failure, be sure to document and replace the item while reaching out to the manufacturer
  • The NCPDP billing units shown in the chart above would apply to non-Medicare Part B claims
  • Beware that any PBM, including Medicare Part B, will recoup or deny a claim if it is refilled too soon based on days’ supply guidelines above
