Post-PHE Claim Submission Requirements for Continuous Glucose Monitors

Centers for Medicare and Medicaid Services (CMS ) did not enforce clinical indications for specific product categories during the Public Health Emergency (PHE), including Continuous Glucose Monitors (CGMs). During this time, the provider only needed to indicate the CGM and related supplies were reasonable and necessary. Pharmacies had to identify that these claims were excluded from enforcement by submitting a Catastrophe/Disaster Related (CR) modifier and a COVID-19 narrative on those claims.

Now that the PHE has ended and CMS is enforcing clinical indications for CGMs and supplies, pharmacies are left wondering what will happen with continued or refilled claims for CGM related supply items initially provided during the PHE under the waiver/non-enforcement.

  • For continued CGM supplies and accessories initially provided during the PHE under the waiver/non-enforcement:
    • Suppliers need to continue to use the CR modifier and COVID-19 narrative for dates of service after May 12, 2023. These actions allow the DME MACs to use new edits on the PHE dispensed items and be able to identify these claims for future review
    • Suppliers should continue to bill the KX, and/or CG modifiers as applicable
    • During the PHE, CMS stated there must be an order and documentation to confirm medical need for items under waiver/non-enforcement
      • Medical need for supplies is typically established and documented when the item is initially provided; Medicare plans to primarily focus medical reviews on claims with initial dates of service after the PHE
      • Potential medical reviews for CGMs would likely occur at least 6 months after the end of the PHE to ensure the treating practitioner has an in-person or approved telehealth visit with the beneficiary to meet the face-to face requirement
    • For a CGM and/or related supplies with initial dates of service on and after May 12, 2023, clinical indications for coverage will be enforced
      • Resources for this coverage criteria:

        • Glucose Monitor/CGM Policy Article
      • Suppliers must be diligent in recognizing when the initial CGM dispensing took place
        • If on or after May 12, 2023, then suppliers need to follow the new LCD coverage requirements for CGMs and related supplies
        • If during the PHE, continue to affix the CR modifier and COVID-19 narrative (where appropriate) and be sure the item continues to be reasonable and necessary to prevent recoupment
