How SSA decides a disability claim — the 5-step evaluation

SSA does not decide disability by diagnosis alone. Every adult claim goes through the same five-step sequential evaluation. SSA stops at the first step that decides the case, so a claim can be denied at step 1 even with a severe condition, and allowed at step 3 even without reaching the question of what work you could do.

The five steps

Are you working above SGA? If your countable earnings are above $1,690 a month in 2026 ($2,830 if statutorily blind), SSA generally finds you not disabled and stops here. Work below SGA moves to step 2.
Is your impairment severe? It must significantly limit your ability to do basic work activities — walking, standing, sitting, lifting, remembering, concentrating, or getting along with others — for at least 12 months.
Does it meet or equal a Listing? SSA's Blue Book (Listing of Impairments) describes conditions considered severe enough to prevent SGA-level work. If your condition meets a listing's exact criteria, or equals one in severity, you are found disabled here. Musculoskeletal conditions are the largest group in the program (34.2% of beneficiaries), but meeting a listing requires the listing's specific medical findings, not only the diagnosis name.
Can you do past relevant work? SSA looks at work you did in the past (generally the last 15 years, with some exceptions) and asks whether you can still do it as you did it or as it is generally done. If yes, the claim is denied here.
Can you adjust to other work? SSA considers your remaining functional capacity together with your age, education, and work experience, and asks whether other work exists in significant numbers in the national economy that you could do. If yes, denied; if no, allowed. Age matters more here than anywhere else in the process: the rules (the “medical-vocational guidelines,” often called the grids) treat workers aged 50 and older, and especially 55 and older, differently from younger workers.

Who actually decides?

Your claim is filed with SSA, but the medical decision at the initial and reconsideration levels is usually made by a state agency called Disability Determination Services (DDS), working under SSA's rules. A DDS team — a disability examiner plus a medical consultant — reviews your medical records, and may ask you to attend a consultative examination if the file is thin. That examination is paid for by SSA and is not a treatment visit: its only job is to fill gaps in the evidence.

What evidence wins claims

Consistent treatment records — regular visits, not a single emergency-room note.
Objective findings — imaging, lab results, and measured limitations, alongside your reported symptoms.
Function, not labels — what you cannot do, in concrete terms (how long you can sit, how much you can lift, how often you must rest), matters more than the name of the condition.
Work history detail — exact job duties and dates, because step 4 turns on what your past work actually required.

If the evidence is incomplete, SSA denies rather than guesses in your favor. That is why How to apply stresses gathering records before you file, and why appeals so often turn on new evidence rather than new arguments.
