How to Review an LTD Offset or Overpayment Demand Before You Repay Anything

Getting a letter that says you were “overpaid” on long-term disability benefits can feel like a punch to the gut. One page says you owe thousands of dollars. Another says future checks may be reduced. Sometimes the insurer points to Social Security, workers’ compensation, retirement benefits, part-time earnings, or a lump-sum payment and treats the issue like the math is already settled.
In reality, these demands are not always as simple as they look.
Many LTD overpayment disputes turn on plan language, timing, benefit categories, attorney-fee treatment, notice requirements, and the insurer’s own calculations. In this post you’ll learn how to review an LTD offset or repayment demand methodically before sending money, what documents often matter most, which mistakes show up over and over, and when an attorney may help evaluate whether the amount is enforceable.
If you want a broader overview of how these disputes arise in the first place, it may help to start with this guide to how disability offsets and repayment demands usually work.

Why An LTD Overpayment Demand Deserves A Careful Review

LTD policies and ERISA-governed plans often allow insurers to reduce monthly benefits by “other income benefits,” but the scope of that offset depends on the actual plan terms. The U.S. Department of Labor explains that disability benefit claims under ERISA are subject to detailed procedural rules, including notice and appeal rights when benefits are denied, reduced, or terminated. The DOL also treats a denial, reduction, or termination of benefits as an adverse benefit determination, which can trigger review rights. Department of Labor guidance and EBSA FAQs discuss these protections.
That matters because an overpayment demand is often tied to a benefit reduction. If the carrier recalculates what it says it owed in prior months, the issue may overlap with the same procedural framework that applies when benefits are cut back. In practical terms, the insurer’s spreadsheet is not always the last word.

What An LTD Offset Usually Refers To

An “offset” is generally a reduction in monthly LTD benefits based on income the policy says can be counted against the disability payment. Common examples include:
  • Social Security Disability Insurance
  • Workers’ compensation
  • State disability benefits
  • certain retirement or pension payments
  • wages or earnings
  • third-party recoveries in some plans
  • dependent Social Security benefits tied to the claimant’s disability
Exactly what counts depends on the governing plan documents. That is why the first question is not “How much do I owe?” but “What does the policy actually permit?”

Step 1: Get The Actual Governing Plan Documents

Before reacting to the demand, gather the documents that control the claim:
  • the full LTD policy or certificate
  • the summary plan description, if the coverage came through work
  • any riders or amendments
  • the reimbursement agreement, if one was signed
  • the overpayment or offset letter
  • prior approval and payment letters
  • benefit statements from Social Security, workers’ compensation, or other sources
The Department of Labor’s benefits guidance explains that the summary plan description and claims-procedure materials are key documents for understanding how a disability plan works and how claims are processed. It also notes that participants can request plan materials from the administrator. DOL booklet.

Why The Paperwork Matters

Insurers often summarize the policy in letters, but the controlling language may be narrower than the summary. A repayment demand may rely on terms like:
  • “other income benefits”
  • “deductible income”
  • “loss of earnings”
  • “estimated benefits”
  • “lump-sum substitute for periodic benefits”
  • “amounts payable to your dependents”
  • “recoverable overpayment”
Each of those phrases can change the math.

Step 2: Identify Exactly What Triggered The Demand

Not every overpayment demand comes from the same event. Start by isolating the trigger:

Social Security Back Pay

This is one of the most common sources of LTD overpayment demands. If the plan allowed the insurer to estimate Social Security and pay a higher LTD amount while the SSA claim was pending, the carrier may later seek reimbursement after a favorable award.
But there can still be disputes about:
  • the covered time period
  • whether dependent benefits count
  • whether attorney fees were treated correctly
  • whether the insurer used gross or net amounts
  • whether the insurer already took a monthly estimate and is double counting
The Social Security Administration states that if it identifies an overpayment, it generally waits at least 30 days before collection begins, and if a waiver or appeal is filed within that window, collection is paused while SSA decides the request. SSA also explains that waiver relief may be available in some circumstances. SSA overpayment page. While that page addresses SSA overpayments rather than LTD insurer claims, it highlights a bigger point: overpayment issues often involve process, not just arithmetic.

Workers’ Compensation Or State Disability Benefits

Some LTD plans offset periodic workers’ compensation payments and also offset lump-sum settlements that substitute for wage-loss benefits. Disputes often arise when a settlement includes multiple categories, such as medical allocation, future benefits, penalties, or attorney fees.

Earnings From Work

Some plans reduce benefits based on current earnings or “rehabilitative” income. Problems show up when the insurer uses the wrong months, gross income instead of the plan’s defined measure, or incomplete wage records.

Retirement, Pension, Or Other Benefits

Whether these count as offsets depends heavily on plan wording. One policy may offset only disability-based retirement payments; another may include broader categories.

Step 3: Match The Claimed Overpayment Period To Real Dates

One of the easiest places to find errors is the timeline.
Create a simple chart with:
  • the date LTD benefits started
  • the months the insurer says it overpaid
  • the effective date of the other benefit
  • the payment date of the other benefit
  • any months where an estimated offset was already being applied
  • any months where LTD was not paid or was paid at a reduced rate
This matters because insurers sometimes use the award date, entitlement date, payment date, and retroactive period interchangeably. They are not always the same.
For example, a Social Security award issued in March 2026 could include retroactive benefits for earlier months. The LTD carrier may be entitled to some offset for overlapping months under the plan language, but the insurer’s chart still has to line up with the actual covered period.

Step 4: Check Whether The Plan Language Really Covers That Income

This is where many demands become more debatable.
Ask these questions:
  • Does the policy clearly define the income source as offsettable?
  • Does it include dependent benefits, or only benefits paid directly to the claimant?
  • Does it treat lump sums as substitutes for monthly benefits?
  • Does it exclude portions attributable to cost-of-living increases, medical expenses, or attorney fees?
  • Does it allow the insurer to estimate benefits before they are awarded?
  • Does it describe how recoverable overpayments are calculated?
The answer often turns on one or two sentences buried in the policy.

Watch For Dependent Benefit Issues

Some LTD plans attempt to offset Social Security benefits paid to a spouse or children because of the claimant’s disability. Others are narrower. If the insurer included family benefits, compare that decision to the exact plan wording instead of assuming it is automatic.

Watch For Attorney-Fee Treatment

In Social Security cases, attorney fees can affect what the claimant actually receives. The SSA explains that it can withhold part of past-due benefits for direct payment of representative fees in qualifying cases. SSA handbook. Whether an LTD carrier calculates its reimbursement using the gross award or some adjusted amount can become a major dispute, especially if the policy language is vague or silent.

Step 5: Request The Insurer’s Full Calculation And Supporting File

If the letter only shows a lump-sum number, ask for the worksheet behind it.
A useful request often includes:
  • month-by-month payment history
  • all calculations used to determine the overpayment
  • copies of the policy provisions relied on
  • the reimbursement agreement
  • Social Security or other award documents used in the analysis
  • notes showing when offsets were first estimated or applied
  • any internal guidelines used to compute the demand
The Department of Labor states that claimants are entitled, upon request and free of charge, to reasonable access to and copies of documents, records, and other information relevant to the claim. Relevant material includes information relied upon, submitted, considered, or generated in making the determination, as well as materials reflecting consistent decision-making safeguards. EBSA FAQ.
That does not automatically resolve the dispute, but it often reveals whether the demand is grounded in actual plan language and clean accounting.

Step 6: Look For Double Counting And Spreadsheet Errors

A surprising number of overpayment disputes are plain math problems dressed up as legal certainty.
Common examples include:

Estimated Offset Plus Actual Award

The insurer may have already reduced monthly LTD checks based on an estimated Social Security amount. Later, when the SSA award comes in, the carrier sometimes calculates the full retroactive award as if no estimate had ever been applied.

Wrong Gross-Or-Net Figure

The letter may use the gross retroactive award even where the claimant never received that entire amount because of direct-paid fees or other withholdings.

Non-Overlapping Months

The insurer may count months outside the overlap period.

Ignoring Prior Recoupment

The carrier may continue reducing benefits after the alleged balance was effectively recovered.

Counting Non-Offsettable Portions Of A Settlement

This comes up in workers’ compensation and other lump-sum resolutions where the settlement covers more than wage replacement.

Step 7: Review Whether The Demand Was Sent Through A Proper Claims Process

When an insurer reduces, terminates, or recoups benefits, process can matter almost as much as substance.
The Department of Labor explains that disability claims under ERISA have timelines for decisions and appeals, and that denied claims must come with a detailed explanation and appeal information. The DOL also explains that on appeal, the review is performed by a new reviewer and includes consideration of all submitted information. DOL benefits booklet.
In the LTD context, questions that sometimes matter include:
  • Was the reduction described as an adverse benefit determination?
  • Did the letter identify the policy language used?
  • Did it explain the calculation clearly enough to evaluate it?
  • Did it provide appeal rights and deadlines?
  • Did it tell the claimant how to obtain the relevant file?
These procedural issues can shape how an attorney evaluates the dispute, particularly in ERISA-governed employer plans.

Step 8: Check For Repayment Pressure Tactics Before Treating The Number As Final

Some letters strongly encourage immediate repayment in one lump sum. Others propose installment plans or begin reducing future benefits quickly. That pressure can make the amount feel nonnegotiable.
It often isn’t that simple.
In some situations, carriers seek repayment because the plan and reimbursement agreement arguably permit it. In other situations, there may be real disputes about interpretation, timing, waiver, estoppel, accounting, or whether the money sought is traceable and recoverable in litigation.
The Supreme Court’s ERISA reimbursement cases are highly fact-specific, but they illustrate an important concept: reimbursement claims can depend on the theory the plan uses and the specific fund it seeks to recover. In Montanile, the dispute centered on whether an ERISA fiduciary could enforce an equitable lien after specific funds had been dissipated. Cornell’s case summary discusses that framework. That does not mean every LTD overpayment demand is unenforceable; it does mean plan recovery rights are often more technical than a form letter suggests.

Step 9: Separate “Do They Claim An Overpayment?” From “Can They Prove This Amount?”

These are two different questions.
An insurer may point to a reimbursement clause and say an overpayment exists. But the enforceability of the specific dollar amount may still depend on:
  • precise policy wording
  • whether the offset category applies
  • whether the months overlap
  • how attorney fees were handled
  • whether prior deductions were credited
  • whether the claimant received proper notice and appeal rights
  • whether federal ERISA rules or state insurance law affect the dispute
That is one reason people facing these demands often benefit from an attorney review before sending repayment.

Step 10: Preserve Your Own Record Before Responding

Before you send money or sign a repayment agreement, organize your file.
A practical record often includes:
  • every letter from the insurer
  • screenshots or PDFs of benefit portals
  • all benefit statements
  • SSA notices and fee notices
  • workers’ compensation settlement papers
  • tax forms tied to benefit payments
  • wage records
  • your own month-by-month spreadsheet
  • notes of phone calls, including dates and names
The Department of Labor notes the importance of keeping copies of claim-related communications and records. DOL booklet.
A clean file helps an attorney evaluate whether the insurer’s demand is accurate, overstated, or procedurally vulnerable.

Questions People Often Ask About LTD Repayment Demands

Can An Insurer Reduce Future LTD Checks Instead Of Suing?

Often, yes, if the plan language allows offset or recoupment from ongoing benefits. But the scope of that right depends on the policy and the claim’s status.

Does A Social Security Award Automatically Mean The LTD Amount Is Correct?

Not necessarily. Social Security decisions frequently trigger LTD reimbursement disputes, but the carrier still has to apply the plan language correctly and calculate the overlap accurately. If you are trying to understand the bigger picture, this article on how offsets from SSDI, workers’ compensation, and other income usually interact gives more context.

What If The Letter Gives A Short Deadline?

Short deadlines are common in overpayment letters. The legal importance of the deadline may depend on the plan, the wording of the notice, whether future benefits are still being paid, and whether the matter is being handled as an appealable reduction in benefits.

What If The Carrier Says I Signed A Reimbursement Agreement?

That may strengthen the carrier’s position, but it does not automatically resolve disputes over the amount, the covered benefit category, or the calculation method.

What If The Overpayment Came From SSA’s Back Pay?

That is common, but it can still involve disputes over family benefits, attorney fees, estimated offsets, and overlap periods. Separately, SSA has its own overpayment and waiver procedures for Social Security debts. SSA guidance.

When An Attorney May Add Value

LTD offset and overpayment disputes often sit at the intersection of insurance contract language, ERISA procedure, benefit coordination, and accounting. That mix can be hard to evaluate from a letter alone.
An attorney may help determine:
  • whether the plan actually allows the claimed offset
  • whether the insurer’s timeline and math hold up
  • whether an administrative appeal makes sense
  • whether supporting documents are missing
  • whether a proposed repayment agreement creates new issues
  • whether the insurer’s recovery theory is narrower than the letter suggests
This is especially relevant when the demand is large, the claim is employer-sponsored, ongoing benefits are still at stake, or the calculation depends on a Social Security award, workers’ compensation settlement, or several overlapping income streams.

The Bottom Line

An LTD overpayment letter can look definitive even when important pieces are still open to challenge. The key issues are usually not just “Did another benefit get paid?” but what the plan says, what months overlap, how the insurer did the math, what documents support the number, and whether the process was handled correctly.
Before repaying anything, many claimants find it helpful to slow the situation down, gather the governing documents, request the full calculation, compare the insurer’s timeline to the actual award paperwork, and evaluate whether the demand reflects the policy’s real terms rather than a broad summary.
