How to Apply for SSDI
SSDI pays monthly benefits to workers who have a qualifying disability and enough work history to have earned sufficient Social Security credits — generally 5 of the last 10 years of work credits. Benefit amounts are based on your average lifetime earnings; the average payment is around $1,537/month in 2024. After 24 months of SSDI, you automatically become eligible for Medicare.

Step-by-Step Application Process
Confirm work credit eligibility
SSDI requires work credits earned from paying Social Security (FICA) taxes. Most applicants need 40 credits, 20 of which were earned in the past 10 years (roughly 5 years of work in the past 10). Younger workers need fewer credits. You can check your credits at ssa.gov by creating a My Social Security account.
Apply online, by phone, or in person
Apply online at ssa.gov/disability — the online process is the fastest option. You can also call 1-800-772-1213 or visit your local SSA office. Apply as soon as you are disabled — the date you apply determines the earliest date benefits can begin (there is a 5-month waiting period before the first payment).
Complete the Adult Disability Report
This form asks about your medical conditions, treatments, how your disability affects daily activities and work, and your work history. Be specific and detailed — describe how your condition affects you on your worst days. Generic answers ("I have back pain") are less persuasive than specific functional limitations ("I cannot sit for more than 20 minutes without severe pain").
Understand the five-step evaluation process
SSA uses a sequential five-step evaluation: (1) Are you working above SGA ($1,550/month in 2024)? If yes, denied. (2) Is your condition "severe"? (3) Does your condition meet or equal a listed impairment? If yes, approved. (4) Can you do your past work? (5) Can you do any other work given your age, education, and limitations? Most approvals happen at step 3 or 5.
Respond to Consultative Examination requests
SSA may schedule an exam with a doctor they contract with if your records are insufficient or unclear. Attend this exam — missing it will result in denial. The exam is typically brief (15-30 minutes) and focuses on functional limitations. Continue your own medical care throughout — gaps in treatment weaken your claim.
Tips and Common Mistakes
- →Apply as soon as you cannot work — the 5-month waiting period means no payment during that time regardless of when you apply.
- →Two-thirds of initial SSDI applications are denied. File an appeal within 60 days of any denial — do not give up or restart your application.
- →Disability attorneys work on contingency (no upfront cost) and are capped at 25% of back pay or $7,200, whichever is less.
- →Keep attending all medical appointments and following prescribed treatments — non-compliance with treatment is a major reason claims are denied.
- →Once approved for SSDI, you become eligible for Medicare after 24 months — even if you are under 65.
After You Apply
SSDI recipients are subject to periodic Continuing Disability Reviews (CDRs) every 3-7 years. Continuing to work during the process is allowed under the Trial Work Period rules — but inform SSA immediately of any return to work. If your condition improves substantially, SSA may discontinue benefits after a CDR.
