The rules say that plans must pay for a medical service or item if regular Medicare would pay for it in this case. You can find this rule at 42 Code of Federal Regulations (CFR) Section 422.101.
The rules state that therapeutic continuous glucose monitors (CGMs) and related supplies are covered by Medicare when all of the following coverage criteria are met: 1. The beneficiary has diabetes mellitus, 2. The beneficiary is insulin-treated with multiple (three or more) daily administrations of insulin or a Medicare-covered continuous subcutaneous insulin infusion (CSII) pump, 3. The beneficiary's insulin treatment regimen requires frequent adjustment by the beneficiary on the basis of BGM or CGM testing results, 4. Within six (6) months prior to ordering the CGM, the treating practitioner has an in-person visit with the beneficiary to evaluate their diabetes control and determined that criteria (1-3) above are met; and, 5. Every six (6) months following the initial prescription of the CGM, the treating practitioner has an in-person visit with the beneficiary to assess adherence to their CGM regimen and diabetes treatment plan. You can find this information in the Local Coverage Determination (LCD): Glucose Monitors (L33822). The quantity of test strips (code A4253) and lancets (code A4259) that are covered depends on the usual medical needs of the beneficiary and whether or not the beneficiary is being treated with insulin, regardless of their diagnostic classification as having Type 1 or Type 2 diabetes mellitus. Coverage of testing supplies is based on the following guidelines: Usual Utilization For a beneficiary who is not currently being treated with insulin administrations, up to 100 test strips and up to 100 lancets every 3 months are covered if the basic coverage criteria (1)-(2) (above) are met. For a beneficiary who is currently being treated with insulin administrations, up to 300 test strips and up to 300 lancets every 3 months are covered if basic coverage criteria (1)-(2) (above) are met. High Utilization For a beneficiary who is not currently being treated with insulin administrations, more than 100 test strips and more than 100 lancets every 3 months are covered if criteria (a) - (c) below are met. For a beneficiary who is currently being treated with insulin administrations, more than 300 test strips and
more than 300 lancets every 3 months are covered if criteria (a) - (c) below are met. Basic coverage criteria (1)-(2) listed above for all home glucose monitors and related accessories and supplies are met; and, Within the six (6) months prior to ordering quantities of strips and lancets that exceed the utilization guidelines, the treating practitioner has had an in-person visit with the beneficiary to evaluate their diabetes control and their need for the specific quantity of supplies that exceeds the usual utilization amounts described above; and, Every six (6) months, for continued dispensing of quantities of testing supplies that exceed the usual utilization amounts, the treating practitioner must verify adherence to the high utilization testing regimen. If neither basic coverage criterion (1) or (2) is met, all testing supplies will be denied as not reasonable and necessary. If quantities of test strips or lancets that exceed the utilization guidelines are provided and criteria (a) - (c) are not met, the amount in excess will be denied as not reasonable and necessary.
