When Your Disability Claim Is Denied Because the Insurer Says You Were Not Actively at Work

You filed a long-term disability claim. Your doctors support you. The medical evidence confirms you cannot work. Then the denial letter arrives, and it does not mention your medical condition at all.

Instead, the insurer points to a clause in your plan called the “actively-at-work” requirement. It says you were not working on a specific date, so coverage never applied to you. The insurer is not arguing that you are healthy enough to work. It is arguing that you were never eligible for benefits in the first place.

If this happened to you, you are not alone. Actively-at-work denials recur across insurers and across policy types, and they are correctable when the plan language and the records do not support the insurer’s position. The insurer’s reading of the clause and its version of the dates often fall apart. The actual plan language and your employer’s records often tell a different story.

This article explains how the actively-at-work clause works, the situations that produce these denials, and the steps you can take to fight back.

Key Takeaways

• An actively-at-work denial is not about your medical condition. It is about a technical eligibility date in your policy.
• Most of these denials turn on a single calendar date. Identifying which date the insurer is testing is the foundation of your appeal.
• You have the right to obtain your complete plan documents and the claim file the insurer relied on. Request both in writing immediately.
• Approved leaves, including FMLA and employer-paid leave, often preserve your eligibility. The plan language controls.
• Your employer’s own records, including timesheets, payroll data, and HR correspondence, often contradict the insurer’s timeline.
• You have 180 days from the denial letter to file your appeal under ERISA. Missing that deadline can end your case.

What Is the Actively-at-Work Requirement?

Most employer-sponsored disability policies contain a clause that says you must be performing the regular duties of your job on a specific date for coverage to apply. That date is usually the day coverage took effect or the day before your disability began.

The clause is buried in the plan document or certificate of insurance. Most people do not know it exists until the denial letter quotes it. The insurer uses this clause to reframe your case from a medical question (are you disabled?) to a calendar question (were you working on this particular day?).

How the Clause Is Typically Written

Most policies require that you were performing the regular and customary duties of your job, for your regular number of hours, on the date the policy specifies. Some policies also require that you were working at the place where your job is normally performed.

Working remotely on a scheduled work day counts as actively at work under most policies. The clause does not require you to be physically present at your employer’s office. If you were doing your job from home on the date in question, the insurer may be applying the clause incorrectly.

An experienced ERISA disability attorney can read the specific clause in your policy and tell you whether the insurer applied it correctly.

Why Insurers Are Allowed to Use This Clause

ERISA permits plan sponsors and insurers to set eligibility conditions, including active-employment requirements. The clause itself is legal. However, the insurer must apply it exactly as written. It cannot stretch the language beyond what the plan document says.

Federal regulations also require the insurer to identify the specific plan provision it relied on when denying your claim. If the denial letter does not cite the exact actively-at-work clause and explain how it applies to your situation, that is a procedural problem you can raise on appeal.

Before responding to the denial, confirm that your plan is governed by ERISA. The appeal procedures and your legal rights depend on which framework applies.

The Dates That Matter

These denials almost always come down to a specific date. The insurer picks one, points to it, and says you were not working that day. Understanding which date the policy tests is the first step in evaluating whether the denial is correct.

Insurers focus on a handful of dates. The most common are the effective date of coverage, the date your disability began, the day before your disability began, and the last day you worked. The effective date is often the first of the month after 30 or 60 days of employment. Some policies also include an elimination period between the date of disability and the date benefits start.

Your employer’s records, including timesheets and payroll, are the best evidence for establishing what happened on the date in question. Request them early.

Common Situations That Lead to Actively-at-Work Denials

We see these denials arise in a handful of recurring situations. Each one has a path through the appeal, but the argument depends on the facts and the plan language.

You Started a New Job and Got Sick During the Waiting Period

You were hired, completed the eligibility waiting period, and coverage was supposed to begin. But on the effective date, you happened to be out sick, at a doctor’s appointment, or working a partial day. The insurer denies coverage because you were not actively at work on that one date.

The first thing to check is whether your policy contains a deferred effective date provision. Many plans say that if you are not actively at work on the scheduled effective date, coverage begins on the first day you return. If that provision exists, coverage attached when you came back to work.

Even without a deferred effective date, the denial may be wrong. A single sick day is not a disability. If you were performing your job the day before and the day after, the insurer’s argument that one absence eliminated your coverage may not hold up.

You Were Promoted and the Insurer Treats It as New Coverage

You moved into a new position with different benefits. The insurer denies your claim by arguing that you were not actively at work in the new role on the date the new coverage took effect.

The question is whether the plan treated the promotion as a new enrollment or a continuation of existing coverage. Many plans include continuity provisions that carry coverage across job changes within the same employer. If your employer processed the promotion as an internal transfer rather than a new hire, the insurer’s argument weakens.

Employer records resolve this. The HR paperwork, payroll records, and how the employer categorized the change in its system are the evidence that matters.

Your Hours Dropped Below the Policy Threshold

Some plans require you to work a minimum number of hours per week, often 30 or more, to remain eligible. If your hours dropped because of a medical condition, the insurer may deny your claim on the ground that you fell below the threshold.

Check the measurement period. Many plans average your hours over a quarter or a full year rather than testing week by week. If your hours were reduced for medical reasons, the same evidence that supports your disability claim can support the argument that you remained eligible during the measurement period.

How Leaves of Absence and Modified Duty Affect Your Eligibility

If you were on an approved leave or working in a modified capacity when your disability began, the insurer may argue that you were not actively at work. These denials can be challenged because approved leaves and modified-duty arrangements often preserve your eligibility under the plan.

Approved Leaves That Typically Preserve Coverage

FMLA leave provides 12 weeks of job-protected leave, and many policies treat it as continuous active employment for eligibility purposes. ADA reasonable accommodation leave and employer-paid sick leave or PTO also typically preserve your active-employment status.

The plan document controls in every case. Get written confirmation from your employer of the type of leave you were on and the exact dates. The denial often turns on whether the leave was approved or unapproved, and your employer’s records are the proof.

The interplay between STD and FMLA leave can complicate the timeline. If you were on short-term disability that ran concurrently with FMLA leave, documenting both separately strengthens the appeal.

If your employment ended during or after leave, that does not necessarily end your right to benefits. What matters is when the disability began. If it began while you were actively employed, disability benefits after FMLA or employment termination usually continue.

Modified Duty and Light-Duty Assignments

If your employer placed you on modified or light duty because of a medical restriction, you were still working. Some insurers argue that modified duty does not count as performing the “regular duties” of your occupation. The counter-argument is strong: you were at work, performing duties your employer assigned, and the policy does not exclude modified duty.

Document the arrangement. An employer letter, HR memo, or email confirming the modified-duty assignment is strong evidence that your employer treated you as actively employed. If the employer considered you actively at work, the insurer’s argument that you were not becomes much harder to sustain.

ERISA Group Plans Versus Individual Disability Policies

Most actively-at-work denials arise under employer-sponsored ERISA group plans. If you bought an individual disability policy on your own, the rules are different.

Under an ERISA Group Plan

You must file an administrative appeal within 180 days of the denial letter. Federal court review is limited to the record built during the appeal. If you win, you recover the benefits owed plus attorney fees. ERISA does not allow bad faith or punitive damages.

Under an Individual Policy

You may be able to go directly to court without filing an administrative appeal. You have the right to a jury trial and full discovery, including depositions of the insurer’s adjusters. Depending on your state, you may also recover bad faith damages and punitive damages.

The procedures and remedies are different enough that it is important to identify which framework governs your claim before responding to the denial.

Why Your Plan Documents and Employer Records Are the Key to Your Appeal

An actively-at-work denial is a documents case. The insurer is making a claim about what the policy says and what happened on a specific date. Your appeal is built by showing that the insurer got one or both of those things wrong.

The Plan Documents You Need

Request the Master Plan Document, the Summary Plan Description, the Certificate of Insurance, and any amendments. ERISA section 104(b)(4) requires the plan administrator to provide these within 30 days of your written request. If the administrator fails to respond, a penalty of up to $110 per day may apply.

Send the request by certified mail and keep proof of mailing. For a step-by-step guide, read our article on how to request your ERISA plan documents.

The Employer Records That Often Defeat the Insurer’s Timeline

The insurer builds its denial on its own reconstruction of your work history. Your employer’s records often tell a different story. Request your timesheets and payroll records for the disputed period. Also request HR records of leave approvals, FMLA designations, and accommodation requests. Get your job description and any modified-duty paperwork, along with email correspondence between you, your manager, and HR about your work status.

In Illinois, the Personnel Record Review Act (820 ILCS 40/) gives employees the right to request a copy of their personnel file. Other states have similar laws.

How to Read the Actively-at-Work Clause in Your Policy

Most denials misread at least one element of the clause. Read it line by line. Check the exact wording: regular duties, regular hours, place of work. Identify the date the clause tests. Look for a deferred effective date provision. Check whether a continuity-of-coverage provision applies to your situation.

Where two provisions in the plan conflict, courts generally apply the reading that favors the participant. Ambiguity in plan language is construed against the drafter, which is the insurer.

Your treating doctor’s role in disability insurance claims also matters here. The physician’s records often establish the timeline of your disability, which may contradict the insurer’s version of when you stopped working.

How to Challenge an Actively-at-Work Denial: Three Steps

Step 1: Get the Plan Documents and the Claim File

Request the complete claim file under 29 C.F.R. section 2560.503-1(h)(2). Request the plan documents under ERISA section 104(b)(4). Request your employer records at the same time. Send all three requests on the same day so the deadlines run together. Keep copies of every request and every response.

Step 2: Build the Eligibility Timeline From Your Records

Map the key dates: your hire date, the eligibility waiting period, the effective date of coverage, the last full day you worked, the first day you were disabled, any FMLA approval date, and your termination date if applicable. Identify which date the denial turns on. Then compare what the insurer says happened on that date with what your employer’s records show.

An appeal built on primary records is stronger than one built on insurer summaries. When employer records and insurer letters disagree, that disagreement favors you on appeal.

Step 3: File the Appeal Within 180 Days

The ERISA appeal deadline is 180 days from the date you receive the denial letter. This deadline is not flexible. Missing it forfeits your administrative review and, in most jurisdictions, your right to go to court.

File the appeal by certified mail with return receipt requested. Address the actively-at-work clause directly: cite the specific provision the insurer relied on and explain, with employer records attached, why the facts defeat the denial. Everything you want a court to see later must go into the appeal now. Under ERISA, courts generally cannot consider evidence that was not part of the administrative record.

If your employment ended before you filed the appeal, that does not mean your claim is dead. Disability benefits after termination usually continue as long as the disability began while you were actively employed.

Frequently Asked Questions About Actively-at-Work Denials

What does actively-at-work mean in my disability policy?

Most employer-sponsored ERISA disability policies define “actively at work” as performing the regular duties of your occupation, for your regular number of hours, on a specific date the policy identifies. That date is usually the effective date of coverage or the day before disability began. The exact wording is in your Certificate of Insurance and Summary Plan Description. These documents are the starting point for understanding why the insurer denied your claim and whether the denial is correct. Request copies of both under ERISA section 104(b)(4) before responding to the denial.

Can I meet the actively-at-work requirement if I was on an approved leave?

Approved leaves often preserve your active-employment status under an ERISA disability plan. FMLA leave, ADA accommodation leave, and employer-paid sick leave or PTO are the most common types of leave that maintain eligibility. The plan document controls in every case. Obtain written confirmation from your employer of the type of leave and the dates, because the denial often turns on whether the leave was approved or unapproved. If the plan treats your leave as continuous active employment, the insurer’s denial on actively-at-work grounds may not hold up.

Can the insurer deny my claim by saying coverage never started?

Yes, but only if the plan language supports that conclusion and the facts match. Some insurers argue that because you were not working on the effective date of coverage, the policy never attached. Check whether the plan contains a deferred effective date provision, which would start coverage on the first day you returned to work. Even without that provision, a single sick day is not a disability and should not block coverage. If you were performing your job the day before and the day after the effective date, the insurer’s position may be difficult to sustain on appeal. DeBofsky Law has challenged these denials by showing that the insurer’s reading of the effective date clause does not match the plan language or the employer’s records.

How long do I have to appeal an actively-at-work denial under ERISA?

You have 180 days from the date you receive the denial letter to file your administrative appeal under ERISA. The plan administrator must provide your plan documents within 30 days of a written request. Calendar both deadlines the day the denial arrives. Starting early gives your attorney time to obtain records, analyze the plan language, and build a thorough appeal. Waiting until the deadline approaches limits your options and weakens the submission.

What happens to my disability benefits if I was terminated while disabled?

If your disability began while you were actively employed, termination after that point does not eliminate your right to disability benefits. The date that matters is when the disability began, not when employment ended. Insurers sometimes conflate the two, arguing that because you are no longer employed, you are no longer eligible. That argument confuses two different questions. The actively-at-work clause tests whether you were working on the date the policy specifies, which is typically a date before the disability began, not after employment ended.

Does the actively-at-work requirement apply to individual disability policies?

Some individual policies contain similar active-employment provisions, though they are less common than in group ERISA plans. The key difference is that individual policies are usually governed by state law rather than ERISA. That means no mandatory administrative appeal before filing suit, the right to a jury trial, and state-law remedies that may include bad faith and punitive damages. If you have an individual policy, a DeBofsky Law attorney can review the specific language and advise you on the correct procedure for challenging the denial.
