Yes. If the noncontract supplier elects to be a grandfathered supplier for these items for beneficiaries renting these items at the time the contract performance period starts, they must agree to continue furnishing the class II CGMs and insulin pumps that were being rented to any beneficiary who wants to continue receiving the CGMs and/or insulin pump from the noncontract supplier. The beneficiary can elect to transition from the noncontract supplier to a contract supplier for the CGM and/or insulin pump at any time during the contract performance period even if the noncontract supplier elected to become a grandfathered supplier. Grandfathering does not apply to situations where the supplier has already received payment for 13 months of continuous use for an insulin pump, the title for which will transfer to the beneficiary at the end of the 13th paid rental month. Grandfathered suppliers of class II CGMs and/or insulin pumps will be paid based on the monthly rental amounts established under the DMEPOS CBP with no cap on the rental payments.
