The Most Common Reasons Your Claim Will Be Rejected

Short-term disability claims are denied most often because you do not meet the definition of disability in your policy, your condition is not covered, or you missed a important date. Unlike Social Security Disability Insurance, which uses a federal standard, short-term disability is a private insurance product — your employer's plan or the plan you bought yourself sets the rules, and those rules are narrower than you might expect.

The single largest reason for denial is that your condition does not prevent you from performing the duties of your own job. Short-term disability does not pay because you are sick or injured in general. It pays because you cannot do the specific work you were hired to do. A software developer with a broken arm might be denied if the policy defines disability as inability to perform "any occupation for which you are reasonably suited by education, training, or experience" — that language means you could potentially do other work, so the claim fails.

The second major category is that your condition is excluded by the policy itself. Pregnancy, mental health conditions, substance use disorders, and self-inflicted injuries are commonly excluded or limited. Some plans exclude injuries that happen during commission of a crime, or conditions that existed before you enrolled. Read your plan document — the exclusions section is where denials live.

Key Takeaways

  • Short-term disability requires that you cannot perform your own job, not that you are generally unable to work, and this distinction causes most denials.
  • Your policy document lists specific conditions or categories that are excluded from coverage, and a claim for an excluded condition will be denied regardless of severity.
  • You must report your disability and file your claim within the timeframe stated in your policy — missing the important date is grounds for automatic denial.
  • The insurer will request medical records and may order an independent medical exam; if your doctor's records do not support that you cannot work, the claim will be denied.
  • Some denials happen because you did not provide required information, such as proof of income, employment verification, or details about other income sources.

Missing the Filing important date or Waiting Period

Every short-term disability policy has a important date for reporting the disability and filing a claim. This is usually 30 to 90 days from the date you stop working, though some plans require notice within days of the event that caused the disability. If you report late, the insurer will deny the claim outright, even if you were legitimately unable to work during the gap.

The policy also specifies a waiting period (sometimes called an elimination period) — typically 7 to 14 days — during which you are disabled but receiving no benefits. If your disability lasts only 5 days, you will not receive any payment because you did not meet the minimum duration. Some plans have different waiting periods depending on whether the disability is work-related or not.

Check your policy document or your employer's benefits summary for the exact important date and waiting period. If you are unsure, contact your plan administrator or human resources department when ready — do not assume you have time.

Your Medical Records Do Not Support the Claim

The insurer will request medical records from your doctor and may order an independent medical exam (IME) performed by a doctor they choose. If those records show that you are capable of working, or if the records are incomplete or vague, the claim will be denied. "I feel terrible" is not enough. The medical evidence must show objective findings — test results, imaging, physical exam findings — that support that you cannot perform your job duties.

Gaps in treatment also hurt your claim. If you stop seeing your doctor for weeks or months, the insurer will argue that your condition improved and you are no longer disabled. Ongoing, documented medical care is essential. If your doctor writes that you are "unable to work" without specifying why or for how long, the insurer may deny the claim as too vague.

Some denials happen because your doctor did not understand what the insurer needed. Your physician may write that you cannot lift more than 10 pounds, but if your job does not require lifting, that restriction does not support a disability claim. Work with your doctor to document the specific job duties you cannot perform and why.

Your Condition Is Excluded or Limited by the Policy

Read the exclusions section of your policy carefully. Mental health conditions are often covered for only 26 weeks instead of the full benefit period. Pregnancy and childbirth may be excluded entirely, or covered only if there are complications. Substance use disorders, self-inflicted injuries, and injuries sustained while committing a crime are commonly excluded.

Some policies exclude conditions that existed before you enrolled (called pre-existing condition exclusions), though federal law limits how long these can explore. Others exclude disabilities caused by war, civil unrest, or high-risk activities. If your condition falls into an excluded category, the claim will be denied even if you meet every other requirement.

A few plans have specific limits on certain conditions — for example, back pain may be covered for only 12 weeks, or migraines may require hospitalization to may have access to. These limits are stated in the policy document. If you are unsure whether your condition is covered, ask your plan administrator before you file.

You Did Not Provide Required Documentation

When you file a claim, the insurer will request specific documents. These typically include your medical records, proof of your income (recent pay stubs or tax returns), employment verification, and details about any other income you are receiving — workers' compensation, unemployment, another disability policy, or income from part-time work. If you do not provide these documents within the timeframe the insurer specifies, the claim will be denied.

Some plans require a statement from your employer confirming that you are not working and describing your job duties. Others require a detailed account of how your condition prevents you from performing those duties. Read the claim form carefully and provide everything requested. If you are missing a document, ask the insurer for an extension rather than submitting an incomplete claim.

Incomplete or inaccurate information is also grounds for denial. If you list income sources incorrectly, or if your medical records contradict your claim form, the insurer may deny the claim. Double-check all information before submitting.

You Are Working or Earning Income During the Disability Period

Most short-term disability policies reduce or eliminate benefits if you are earning income from any source during the period you claim to be disabled. This includes part-time work, self-employment, freelance income, or even volunteer work if it is substantial. Some plans allow you to earn up to a certain percentage of your normal income without losing benefits; others have a zero-tolerance rule.

The insurer will investigate whether you are working. They may contact your employer, review your tax returns, or search public records. If they find evidence that you earned income during the disability period, they will deny the claim or demand repayment of benefits already received.

Be honest about any income you are receiving. If you are unsure whether a particular activity counts as work under your policy, ask the insurer before you engage in it.

The Insurer Determines Your Condition Is Not Disabling Under the Policy Language

Short-term disability policies use specific language to define what counts as a disability. The most common definition is that you cannot perform the duties of your own occupation. Some policies use a stricter standard: you cannot perform any occupation for which you are reasonably suited by education, training, or experience. Others use a looser standard: you cannot perform any gainful occupation.

The insurer will interpret this language based on what your job actually requires. If you are a surgeon with a hand tremor, you are clearly disabled under any standard. If you are an office manager with anxiety, the insurer may argue that you can perform office work even if your current employer has accommodated you by reducing your hours or changing your duties. The policy language determines the outcome.

This is where many denials happen: the insurer's interpretation of the policy language differs from yours. You believed you were disabled because you could not do your specific job; the insurer believes you are not disabled because you could do some other job. Understanding your policy's definition of disability before you file can help you anticipate this issue.

You Did Not Meet the Own-Occupation Definition

If your policy uses an own-occupation definition, you must prove that you cannot perform the specific job you held when you became disabled. This is the most favorable definition for claimants. If your policy uses an any-occupation definition, you must prove that you cannot perform any job for which you are reasonably suited — a much higher bar.

Some policies switch definitions partway through the benefit period. You might have own-occupation coverage for the first 24 months, then switch to any-occupation coverage for months 25 and beyond. If your claim extends into the any-occupation period, the insurer may deny continued benefits because you could theoretically do other work, even if you cannot do your original job.

Check your policy document for the exact definition and any time limits on it. This detail determines whether your claim will be approved or denied.

Frequently Asked Questions

Can I appeal a short-term disability denial?

Yes. Your policy document includes an appeal process, usually requiring you to submit additional medical evidence or documentation within 30 to 60 days of the denial. The appeal goes to the same insurer or to an independent reviewer, depending on your plan. Gather new medical records, a detailed letter from your doctor explaining why you cannot work, and any other evidence that addresses the reason for the denial.

What if my doctor says I am disabled but the insurer's doctor says I am not?

The insurer will weigh both opinions. If the independent medical exam contradicts your doctor's assessment, the insurer may deny the claim or request more information. You can submit a rebuttal from your doctor addressing the independent exam's findings, or request an independent medical exam of your own at your expense to create a third opinion.

Does short-term disability cover mental health conditions?

Most plans do cover mental health conditions, but often with limits — shorter benefit periods, higher waiting periods, or requirements for hospitalization or intensive treatment. Some plans exclude certain diagnoses. Check your policy document or contact your plan administrator to learn what mental health coverage you have.

If I am denied short-term disability, can I file for Social Security Disability?

Yes, but Social Security Disability has a much stricter definition of disability and a longer approval process. A short-term disability denial does not affect a Social Security claim, and vice versa. The two programs use different standards and different evidence. You can pursue both simultaneously.

What happens if I return to work before my benefits end?

Your benefits will stop on the date you return to work, even if you return part-time or on a modified schedule. Some plans allow a brief transition period with reduced benefits if you return gradually, but this varies. Notify your plan administrator when ready when you return to work to avoid overpayment.
