What Illness Qualifies for Short-Term Disability?

There is no nationwide list of illnesses that automatically qualifies someone for short-term disability income. The question is whether a covered illness, injury, or pregnancy-related condition prevents you from working under your plan's definition of disability for the required period. The U.S. Department of Labor says definitions vary by plan. A diagnosis alone may not establish a claim, and two people with the same condition can have different work restrictions and coverage.

Check the work limitation, not just the diagnosis

Read your policy or employer's Summary Plan Description for the covered conditions, what job duties you must be unable to perform, any waiting period, benefit percentage, maximum duration, and exclusions. A surgery, serious illness, injury, or pregnancy-related recovery may be covered when it meets those rules; a particular label is not a promise of payment. Ask your clinician to document the condition, treatment, functional limits, and expected dates you cannot perform the relevant duties. Confirm whether the plan requires a specific claim form or periodic updates.

File the claim and keep the records

Contact the employer's benefits administrator or the insurer as soon as you know you may miss work. Request the plan document and claim instructions, submit the medical certification the plan asks for, and keep copies of every form and decision. For ERISA-covered employer plans, the Department of Labor's disability-claim guide explains the decision and appeal process. A denial notice must explain the reasons and how to appeal; the guide says you have at least 180 days to request review of a denied claim under those rules.

Income benefits and job-protected leave are different

Short-term disability insurance replaces some income if a covered claim is approved. It does not itself guarantee that your job is protected. The Family and Medical Leave Act may provide eligible workers at covered employers with job-protected leave for a qualifying serious health condition. State leave or disability laws may add rights. Ask HR which benefits and leave protections apply together, when each begins, and what happens if the disability benefit ends before you can return.

If you are buying an individual policy, compare exclusions, pre-existing-condition rules, waiting period, benefit cap, and renewal terms before relying on it. For a disputed claim, contact the plan administrator or your state insurance department for the applicable process.
