- Before You Go Ongoing
Build your medical evidence file
Your records decide if you win or lose your SSDI case. How sick you feel does not decide it. See your doctors on a regular basis. Follow their treatment plans. Gaps in care look bad to the people who review your case. Collect your records. Get your diagnoses, scans, lab results, and treatment history. Also get a written statement from your doctor. It should say what you can and cannot do.

- Follow Up 60-day deadline
Appeal within 60 days — do not just re-apply
If SSA denies you, file for Reconsideration within 60 days. If SSA denies you again, ask for a hearing with an Administrative Law Judge. Most people win their claims at this stage, with help from a representative. Do not just start a new application from zero. A new application resets your earnings record and can cost you back-pay. Most people use a disability lawyer. The lawyer only gets paid if you win. The fee is 25% of back-pay or $9,200, whichever is less.

Be Careful
Don't make these mistakes
Applying with thin medical records. Your records decide if you win or lose your SSDI case. How sick you feel does not decide it. See your doctors on a regular basis, follow their treatment plans, and collect your diagnoses, scans, lab results, and a written statement from your doctor saying what you can and cannot do.
Waiting to apply. Apply as soon as your disability starts. Benefits do not start until after a 5-month waiting period. There is no waiting period for ALS.
Missing an SSA letter or deadline. Reply to every SSA letter right away. If you miss a deadline, SSA can close your claim and you would have to start over.
Starting a brand new application after a denial. If SSA denies you, file for Reconsideration within 60 days. Do not just start a new application from zero. A new application resets your earnings record and can cost you back-pay. Most people win their claims at the hearing stage, with help from a representative.
Not telling SSA about work. Tell SSA about all your work. A trial work period lets you test work for 9 months, and in 2026 a month counts toward it if you earn over $1,210 in that month. The cutoff for substantial gainful activity is $1,690 a month if you are not blind, and $2,830 a month if you are blind. Reporting your work helps you avoid overpayments.
