Common Reasons Short Term Disability Can Be Denied

When battling your insurance company over the disability benefits you require to survive, it’s difficult to prioritize your health. Based on decades of experience in this area, we’ve identified the five most common reasons short term disability can be denied.

Insufficient Medical Information

What it means: They believe there isn’t enough objective medical evidence to justify short term disability leave.

Frequently, they will request detailed medical information as a follow-up to your diagnosis, which complicates the process and leads to a denied claim. The truth is this decision is complicated and, as such, should not be made by insurance company middlemen but by doctors who understand your unique medical conditions.

You Do Not Meet the Definition of Disability

What it means: They believe you can work, either because your situation isn’t severe enough or your condition isn’t considered a disability.

These denied claims are pretty common with “invisible” medical conditions, like chronic pain, chronic fatigue, or mental illness. While this may sound like a final word on your disability claim, the insurer could be making a subjective decision to override your doctor’s medical expertise. If a doctor is supporting your disability claim and leave, then disability lawyers can absolutely help you challenge your denial.

The Insurance Company, or its Doctors, Believe You Can Work

What it means: They believe you are able to work.

The insurance company employs its own doctors, who may review your claim and decide there is insufficient medical evidence—or come to a decision counter to your doctor’s diagnosis altogether.

Often, these insurance company doctors only spend a cursory amount of time reviewing your disability claim. While medical treatment and opinions can differ, speaking to a doctor who knows you, your condition, and your best interests is crucial.

You Have a Preexisting Condition

What it means: Your condition existed before your disability benefits and insurance coverage began, which disqualifies you for short term disability.

A pre-existing policy exclusion only applies early in your coverage—typically in the first year. This is a highly technical situation in which getting a lawyer to properly and thoroughly review your case and prior medical treatments is critical.

Insurance Company Surveillance

What it means: Private investigators probe into your life and activities when you seek disability benefits.

Often, the information they present to question your credibility isn’t even objective proof that you’ve been “caught in a lie”—merely that they have jumped to conclusions without full context and used that assumption to deny your short term benefits claim.

FAQs: Short Term Disability Denied

Can I be fired if my short-term disability is denied?

No, being denied short-term or long-term disability benefits isn’t a valid reason for being fired. However, your employer may ask you to return to work or let them know if you plan to appeal the decision.


Every case is different, so if you're unsure about what to do, it’s a good idea to get legal advice.

Can an employer deny short-term disability?

In most cases, your employer doesn’t handle the approval or denial of your disability claim. The insurance company or a third-party administrator typically manages this.


Your employer may follow their recommendations but usually isn’t involved in the decision itself.

Can short-term disability be denied for pre-existing conditions?

Most short-term disability plans don’t include a pre-existing condition exclusion, so it’s rare for claims to be denied because of this.


Pre-existing condition rules usually apply to long-term disability claims, especially if the policy has been in place for less than a year.

Can short-term disability be denied for mental health issues?

No, a claim cannot be denied just because it’s related to mental health.


However, if your policy has a pre-existing condition clause, it could apply, but this would be the same for any medical condition, not just mental health issues.

“Share Lawyers are amazing. I hurt my back in 2014 and tried everything to keep working until 2020. I could no longer manage—so many hospital trips, medication, physio, massage, and chiro. On and off work, I had no personal life as I was constantly trying to recover enough to return to work. My insurance was pressuring me, and I felt confused, not knowing how to cope with my chronic pain. I was denied long-term disability, cut off from short-term, and living on my credit line. I felt hopeless and frustrated.

I made the call, and Share Lawyers jumped in so fast, taking all my info, medical records, and insurance details. Within weeks, I was accepted for long-term disability and CPP disability. The stress and anxiety went down, and I finally got to focus on my health. Their fees were surprisingly low for the incredible service, knowledge, and support they provided.

I received back pay from insurance, and Share Lawyers continued to offer updates and support. I would recommend them to anyone—friendly, understanding, patient, and fast. Don't let the insurance company make you doubt yourself. Let Share Lawyers handle what they're great at while you focus on your health. Thank you, Share Lawyers!”
