The Modular Disability Folder (MDF) is the official folder for paper cases. It promotes
uniform assembly for all disability claims processing components within the Social
Security Administration and the Disability Determination Services (DDS). For general
information about using the MDF, see DI 70005.005.
NOTE: Public contact personnel should not disclose disability claim determinations or decisions
to a claimant or claimant representative until case processing is complete.
