Getting denied for short-term disability benefits can feel disorienting fast. One day you’re trying to manage a health condition and missed work. The next, you’re reading a denial letter full of plan language, deadlines, and references to “insufficient medical support” or “not disabled under the policy.”
If that sounds familiar, you’re not alone. Early wage-replacement disputes often happen when people are at their most vulnerable: right after a medical event, during treatment, or while trying to coordinate leave paperwork, doctor notes, and employer forms at the same time.
In this post you’ll learn what short-term disability is, why these claims get denied so often, how short-term disability interacts with FMLA and workplace accommodations, what deadlines can matter, and when a lawyer may help evaluate the denial before the next benefit window closes. If you want a broader overview of the recurring issues behind these disputes, it may also help to read our guide on why early disability claims get tripped up by waiting periods, medical proof, and transition issues.

A short-term disability denial is a refusal to pay wage-replacement benefits after an employee submits a claim under an employer-sponsored plan or an individual disability policy.
In general terms, short-term disability benefits are designed to replace part of your income when a medical condition keeps you from working for a limited period. These benefits are different from health insurance. Health insurance pays for medical care; short-term disability is typically about income replacement during a covered period of disability.
A denial can happen at several stages:
The legal framework can vary. Some employer-sponsored disability plans are governed by ERISA, the federal law that regulates many employee benefit plans. The U.S. Department of Labor explains that ERISA-covered health and disability plans have claims-procedure rules, including notice requirements and appeal rights. For disability claims, plans generally have up to 45 days to decide an initial claim, with extensions available in certain circumstances, and claimants generally have at least 180 days to seek review of a denial under covered plans (Department of Labor overview; 29 C.F.R. § 2560.503-1; DOL compliance assistance).
That said, not every short-term disability arrangement is governed by ERISA. Some are structured as payroll practices, some are individual insurance products, and some are tied to state insurance rules instead of federal benefit-plan rules. That distinction often affects appeal procedures, deadlines, and litigation options.
This is one of the biggest sources of confusion.
The Family and Medical Leave Act is about job-protected leave for eligible employees of covered employers. It does not itself provide wage-replacement benefits. The Department of Labor explains that eligible employees may take up to 12 workweeks of unpaid, job-protected leave for certain qualifying family and medical reasons, with continuation of group health coverage under the same terms during leave (DOL FMLA overview; Fact Sheet #28).
Short-term disability, by contrast, is typically a pay benefit, not a job-protection statute.
