Social Security Disability Insurance (SSDI)

What this actually is

SSDI pays you, and in some cases your family members, if you have a disability and worked long enough paying Social Security taxes. It is tied to your work record — you paid for it out of every paycheck. Applying is free; you can apply online, by phone or in person. Two hard truths: there is a five-month waiting period after approval before benefits start, and first applications are frequently denied, so the appeal is part of the ordinary process rather than a sign your claim is bad.

Who qualifies, and what trips people up

Eligibility depends on your age, your disability, and how long you worked. Family members may qualify on your record. If your work history is too short you may still qualify for SSI instead, and SSA considers both from one application. What trips people up: missing medical evidence. The decision is made on the file, so the names and dates of every treating doctor matter more than how you describe the condition.
