Billing for Mail Order Items

50.6 - Billing for Mail Order Items (Rev. 1544, Issued: 06-26-08, Effective: 07-01-08, Implementation: 07-07-08) The “KL” modifier has been established for use in submitting claims for mail order DMEPOS items (e.g., diabetic supplies). Beneficiaries who maintain a permanent residence in CBAs for which there is a competitive bidding program for mail order diabetic supplies may choose to obtain their diabetic supplies through mail order or at a storefront. A beneficiary who resides in a CBA and chooses to obtain their diabetic supplies through mail order must obtain these supplies from a contract supplier for mail order diabetic supplies for the CBA where they maintain a permanent residence. Claims for mail order diabetic supplies furnished to beneficiaries who maintain a permanent residence in a CBA must be billed with the modifier “KL”. If the beneficiary chooses to obtain their diabetic supplies at a storefront, DMEPOS competitive bidding rules do not apply and these claims will be processed under the normal guidelines for supply claims. See §20.5.3 for additional information on mail-order contract suppliers of diabetic supplies.
