If you have received a long-term disability denial – or are researching the claims process before filing – one of the first things you may want to know is how common denials are.

Understanding the broader landscape of disability insurance claim approval and rejection rates can provide useful context, help calibrate expectations, and inform how seriously to take the appeal process.

The answer is that denial rates vary considerably depending on the insurer, the type of policy, the nature of the condition, and the stage in the claims process. But the available data makes clear that denials are common, and that appeals frequently succeed when pursued properly.

For a broader overview, see our guide to long-term disability denial basics.

General Statistics on Disability Claim Denials

Comprehensive, industry-wide data on long-term disability denial rates is not publicly available in a single consolidated source, partly because insurers are not required to publish their individual denial rates in uniform formats. The data that does exist comes from insurer filings with state insurance departments, the Social Security Administration’s annual reports, litigation records, and research by disability advocacy organizations and law firms.

Available estimates suggest that initial denial rates for long-term disability claims range broadly, with some sources indicating that roughly one-third to nearly half of all initial LTD claims are denied. These figures differ significantly across conditions, insurers, and policy types.

For ERISA-governed employer plans specifically, the Department of Labor has documented denial rates in its reviews of large plan administrators. These reviews have found that some major disability insurers deny initial claims at rates between 25% and 40%, depending on the insurer and the claim category.

Short-Term vs. Long-Term Disability Denial Rates

Short-term disability (STD) and long-term disability (LTD) claims are not interchangeable, and their denial rates reflect different dynamics. Short-term disability claims are filed more frequently, tend to involve more straightforward conditions, and are typically resolved faster. Long-term disability claims involve conditions that have already persisted for a substantial period and require more extensive documentation to support.

Initial denial rates for short-term disability claims are generally lower than for long-term disability claims. This is partly because many short-term claims are granted initially and then terminated or not converted to LTD once the short-term period ends. A claimant who exhausts their short-term benefits may then need to file a separate LTD claim and face a fresh review process.

Long-term disability denials also occur not just at the initial claim stage, but during ongoing claims through benefit terminations. An insurer may approve a claim initially and then later terminate benefits by concluding that the claimant has improved sufficiently to return to work, or by applying a stricter definition of disability when the policy transitions from own-occupation to any-occupation standards.

Why Denial Rates Vary

Denial rates are not uniform across conditions, insurers, or policy types. Several factors account for the variation.

Condition Type

Claims based on conditions that are difficult to verify objectively – such as chronic pain, fibromyalgia, chronic fatigue syndrome, and certain mental health conditions – face higher denial rates than claims based on conditions documented by clear diagnostic evidence such as cancer, spinal cord injuries, or advanced degenerative disease visible on imaging. Insurers have more latitude to dispute functional limitations when the primary evidence is subjective symptom reporting.

Insurer Practice

Different insurers have different claim management practices. Some are more aggressive in contesting claims, deploying IME physicians, field investigators, and vocational experts as a standard part of their review process. Others are more deferential to treating physician opinions in straightforward cases. Litigation history and regulatory actions against specific insurers are publicly available and can indicate whether a given carrier has a pattern of denying claims aggressively.

Policy Type: Employer vs. Individual

The type of policy – group employer-sponsored versus individually purchased – affects both the denial rate and the rules governing the appeals process. Group ERISA plans offer insurers certain protections in litigation, including the ability to have their claim decisions reviewed under a deferential ‘arbitrary and capricious’ standard in federal court. This standard makes it harder for claimants to prevail in court and may factor into insurers’ calculation that aggressive claim denials carry limited judicial risk.

Individual policies purchased directly from an insurer are governed by state law and are generally subject to de novo review in state court litigation – meaning the court evaluates the claim fresh, without deference to the insurer’s administrative decision. This different litigation posture may influence how readily individual policy claims are denied and litigated.

What Denial Statistics Mean for Claimants

The existence of significant denial rates does not mean that most claims are wrongly decided. Some denials are appropriate because the claimant does not meet the policy’s definition of disability. But the data also reflects that a substantial portion of denials are challenged successfully on appeal.

Research by disability insurance attorneys and advocacy organizations has found that claimants who file properly documented, evidence-supported appeals have meaningfully higher success rates than those who do not appeal or who file inadequate appeals. This finding reinforces the importance of treating the appeal as a serious and complete evidentiary submission rather than a procedural formality.

ERISA statistics from the Department of Labor have shown that administrative appeals of group disability denials succeed at rates that can reach 50% or higher in well-documented cases. The success rate in appeals handled by experienced disability attorneys tends to be higher than in self-represented appeals, particularly in complex cases involving contested medical evidence or policy interpretation disputes.

Terminations vs. Initial Denials

It is worth distinguishing between initial claim denials – where benefits were never approved – and benefit terminations, where benefits that were being paid are stopped. Both are common in the LTD context. Terminations often occur when a claimant reaches the transition point between own-occupation and any-occupation definitions, or when the insurer conducts a periodic review and concludes based on updated records or an IME that the claimant is capable of returning to some form of work.

Terminations carry the same administrative appeal rights as initial denials under ERISA and most state laws. Claimants who receive a benefit termination notice should respond with the same urgency and strategic preparation as those who receive an initial denial.

The Role of Documentation in Claim Outcomes

Denial statistics are not static – they are a function of how well claims are documented. Claims that are filed with detailed, functional medical evidence, supportive physician statements, and documentation that directly addresses the policy’s definition of disability are approved at higher rates than claims based primarily on diagnosis alone.

For claimants who are still in the initial filing stage, investing time in obtaining comprehensive medical documentation before filing can meaningfully reduce the likelihood of an initial denial. For those who have already been denied, the appeal is the opportunity to provide that level of documentation.

Conclusion

Long-term disability denials occur regularly across the insurance industry, with initial denial rates varying broadly depending on the insurer, the condition, and the policy type. These numbers reflect a combination of appropriately denied claims and claims that could be successfully challenged with better documentation and properly pursued appeals. Claimants who understand the process, file well-documented claims, and respond to denials with thorough appeals are in a substantially better position than those who accept an initial denial as the final word.
