What is a DIF form?
Beginning October 1, 2006, a new form called a DIF (DME MAC Information Form) became available for suppliers to use in place of the enteral nutrition CMN (Certificate of Medical Necessity) when billing Medicare Part B. The DIF served the same purpose as the CMN with some variances. CMNs required a physician’s signature and a narrative description of equipment and products. A DIF is completed and signed only by the supplier. When using the DIF, the physician’s signature and narrative description, including patient-specific medical necessity information, is still required but can be obtained by the supplier via verbal and written orders. The suppliers are required to keep this information in their files. Suppliers are responsible for the accuracy of all patient information on the DIF.
