Yes, you can upload your medical records in the SSA portal for DDS or you can also use the Electronic Records Express system.
To upload your medical records inn your SSA portal using your My Social Security Account, log in to your personal my Social Security account and then go to the Upload Documents feature and attach your digital medical records like PDFs, and then submit them.
You can also use the Electronic Records Express, which is a dedicated system that allows claimaints, attorneys, and medical providers to submit health records and school records directly to the State Disability Determination Services or DDS.
However things to keep in mind are the file limits, processing and review and follow up recommendation.
Each submission via the standard portal cannot exceed 50 files, and individual files must be under 25MB (limits may vary slightly depending on whether you use ERE).
While documents uploaded to the portal route into your electronic claim folder (eFolder) for DDS to review, processing speeds can vary.
Many SSA applicants and representatives choose to call their local SSA field office or assigned DDS examiner a few days after uploading to confirm that the files are visible and attached to the active case.
However uploading your medical records is not usually necessary as if you give the DDS your doctors information they can request and get the medical records on your behalf.
