SSDI Vs. Short-Term Disability Insurance

Published:

Social Security Disability Insurance (SSDI) and short-term disability both provide income when an injury prevents you from working, but they have major differences.

This article explains SSDI versus short-term disability insurance including the differences, if the benefits can overlap, and when you may be eligible for either benefit.

Main Difference Between SSDI and Short-Term Disability

Short-term disability insurance is temporary and SSDI is long-term.

Short-term disability insurance provides partial wage replacement when you have an injury or illness that’s not work-related. A work-related injury is usually handled through workers’ compensation. Either your employer provides the private disability insurance or you pay for it yourself. 

SSDI is a federal benefit that provides wage replacement when a condition prevents you from working a substantial amount for at least 12 months or is expected to result in death. It’s based on taxes you’ve paid into Social Security through work.

SSDI Vs. Short-Term Disability at a Glance

This table helps you compare SSDI and temporary disability benefits side by side.

Category SSDI
Main purpose Long-term disability benefit Temporary wage replacement
Who runs it Social Security Administration Private insurer or state
Who may qualify Workers with enough Social Security work credits who meet disability rules Workers covered by a policy
Duration As long as you meet disability rules Six to 52 weeks
Medical standard Condition must be expected to last at least 12 months or result in death Depends on the policy or state rules

How SSDI Works

When a health condition will prevent you from working a substantial amount for at least a year (or result in death) and you have enough work credits, you may meet SSDI eligibility rules. You earn work credits by paying Social Security taxes through jobs or self-employment. The number of credits you need depends on your age.

You must also have worked recently enough to be insured. Typically, you’re insured for about five years after you stop working. Learn more about the “date last insured” requirement and other key dates for SSDI.

SSDI is managed by the Social Security Administration (SSA). Getting approved for SSDI usually takes five to eight months unless your claim is fast-tracked. After approval, there’s a five-month SSDI waiting period before benefits start, except in cases of Lou Gehrig’s Disease. That’s because the SSA wants to make sure only people with long-term conditions get SSDI.

How Short-Term Disability Works

Short-term disability insurance replaces 40-70% of your wages when you can’t work for medical reasons. Either you or your employer pays for short-term disability insurance. California, Hawaii, New Jersey, New York, and Rhode Island have state disability insurance or state-mandated short-term disability programs. 

Rules and benefits depend on your short-term disability policy or state program. The average policy provides benefits for 13-26 weeks, although some pay for up to 52 weeks.

Short-term disability covers illnesses and accidents, surgery and recovery, pregnancy complications, and sometimes maternity leave. Some plans also cover alcohol or drug rehabilitation. Policies usually don’t cover cosmetic procedures, injuries related to a crime, or self-inflicted injuries.

Typically, you get short-term or temporary disability benefits in two weeks or less. It’s meant to provide almost immediate help when you can’t work.

Can Short-Term Disability and SSDI Overlap?

You can apply for SSDI while receiving short-term disability if your doctors expect your condition to keep you from doing substantial work for at least a year. The SSA uses the term Substantial Gainful Activity (SGA) to measure substantial work. SGA limits change almost every year. Check the current limit. 

The SSDI approval process can take months or even a year or more, and the SSDI waiting period comes after approval, so you want to apply as soon as you qualify. The SSA won’t approve you for SSDI just because you get short-term disability benefits. You must meet the SSA’s strict disability rules, have the work credits, and have medical evidence to prove your impairment.

If you get approved for SSDI while receiving short-term disability, your short-term disability benefits may be reduced or end when you start getting SSDI. If you have dual benefits and are overpaid by the short-term insurance provider, you might have to repay benefits. Read your policy for its specifics and contact the insurer if you have questions.

What if Short-Term Disability Is Ending and You Still Can’t Work?

Talk to your medical providers about the expected duration of your condition. Medical evidence from your doctor’s records must confirm that you won’t be able to earn SGA thresholds for at least a year to get SSDI. 

If you have long-term disability insurance through your employer or another private disability insurance policy, that is probably your best next source of help. You may still be able to enroll, but the policy might not cover conditions that you had before enrolling. Ask about the pre-existing condition terms of the policy to see how it fits your situation.

The Family and Medical Leave Act (FMLA) may provide job protection for a few months, but it doesn’t provide monetary benefits.

Should You Use SSDI or Short-Term Disability First? 

The details and duration of your condition indicate which program is the best fit for your situation. If you have a work-related injury or became ill because of your work, you likely have a workers’ compensation claim. 

If you expect to return to work in weeks or months and you have a short-term disability policy, that policy is usually your best option for short-term help. 

If you meet the SSA’s disability rules but don’t have enough work credits for SSDI, you may qualify for Supplemental Security Income (SSI) when your short-term disability ends. SSI is for people with limited income and resources. All earned and unearned income, gifts, and some living arrangements are counted as income or resources so you may not qualify while receiving short-term disability benefits.

Frequently Asked Questions

Is SSDI the same as short-term disability?

No. SSDI is a federal benefit for long-term disability cases. Short-term disability is temporary wage replacement insurance.

Can I apply for SSDI while on short-term disability?

Yes, if your condition is expected to prevent substantial work for at least 12 months or result in death. Short-term disability approval doesn’t guarantee SSDI approval.

Does short-term disability reduce SSDI?

No, but the short-term disability policy may have a clause about reducing or ending benefits when you start getting SSDI.

What happens when short-term disability ends?

If you still cannot work, your other options are private or employer long-term disability, FMLA, or SSDI or SSI if your condition meets SSA rules. Here’s a comprehensive guide for SSDI applications.
