The medical and work tests are separate
A strong work history alone does not establish disability, and a serious diagnosis alone does not establish insured status. SSA evaluates whether the condition meets its duration and work-impact rules, then checks whether the worker earned enough credits recently enough.
How credits are earned in 2026
SSA states that one credit is earned for each $1,890 in covered earnings in 2026, up to four credits for the year. Earning more than the four-credit threshold does not add extra credits, and the credit amount changes annually.
How many credits may be needed
SSA says workers generally need 40 credits in total, including 20 earned during the 10 years ending with the year disability begins. The exact requirement depends on age, and younger workers may qualify with fewer credits. A person who meets SSA’s statutory-blindness rules must meet the duration-of-work test but does not have to meet the recent-work test.

Your Social Security account is the best place to review your earnings history and whether SSA currently shows enough work. Correct missing earnings promptly and avoid estimating insured status from years worked alone.
