The Disability Determination Services (DDS) provides a personalized disability notice
(PDN) to the claimant in the event of a medical denial or when the DDS establishes
the onset of disability later than the date of the Title XVI application.
When the DDS makes a fully favorable determination, the field office (FO) processing
the claim sends out the initial award notice automatically through the Modernized
Supplemental Security Income Claims System (MSSICS) for most cases.
