Long-Term Disability Glossary: 30 Terms Every Claimant Should Know

Understanding your long-term disability (LTD) insurance policy can be challenging, particularly when you are dealing with a serious illness or injury, financial uncertainty, and an insurance company evaluating your eligibility for benefits.

Disability insurance policies contain specialized medical, legal, and contractual terminology that can directly affect whether your claim is approved, how much you receive, and how long your benefits continue. Misunderstanding even one provision could affect your ability to protect your rights.

At DarrasLaw, our attorneys help policyholders navigate complex disability insurance claims, appeals, and litigation involving individual and employer-sponsored policies.

This long-term disability glossary explains 30 essential terms every claimant should understand, including how these terms can influence the outcome of a disability insurance claim.

Understanding Long-Term Disability Insurance: Key Terms at a Glance

Long-term disability insurance generally provides partial income replacement when a covered illness or injury prevents an insured person from working as defined by the policy.

However, receiving a medical diagnosis does not automatically establish eligibility for LTD benefits. Insurance companies evaluate claims according to the policy’s disability definition, exclusions, medical documentation requirements, and other contractual provisions.

The following glossary covers the terminology most frequently encountered throughout the disability claim process.

30 Essential Long-Term Disability Insurance Terms

1. Long-Term Disability (LTD) Insurance

Definition: Long-term disability insurance is coverage designed to replace a portion of an insured person’s income when a qualifying illness or injury prevents them from working for an extended period.

LTD benefits typically begin after a specified waiting period and may continue for a defined number of years, until a particular age, or for another period established by the policy.

Eligibility depends on satisfying the policy’s definition of disability and complying with its claims requirements.

Why it matters: Disability insurance policies differ considerably in how they define disability, calculate benefits, and determine when payments terminate.

2. Elimination Period

Definition: The elimination period is the waiting period that must be satisfied under a disability insurance policy before benefits become payable.

Common elimination periods include 90 and 180 days, although other periods are possible.

For example, a policy with a 90-day elimination period generally requires a claimant to satisfy the applicable disability requirements during that period before benefits become payable.

Why it matters: Understanding your elimination period helps you anticipate when benefits may begin and plan for potential gaps in income.

3. Own-Occupation Disability

Definition: Own-occupation disability is a policy standard that evaluates whether an insured person can perform the duties of their regular or specified occupation because of illness or injury.

The exact definition varies. Some policies focus on the occupation as performed in the national economy, while others consider the insured’s particular professional duties.

For example, a surgeon who develops a neurological condition affecting fine motor coordination may be unable to perform surgical procedures even if they remain capable of certain administrative tasks.

Why it matters: Own-occupation provisions can be particularly significant for physicians, dentists, executives, attorneys, and other specialized professionals whose occupational duties require particular skills.

4. Any-Occupation Disability

Definition: Any-occupation disability is a standard that generally evaluates whether a claimant can perform another occupation that satisfies the policy’s requirements, rather than focusing solely on their previous job.

Depending on the policy, the evaluation may consider the claimant’s education, training, experience, functional capacity, and potential earnings.

Many group LTD policies transition from an own-occupation standard to an any-occupation standard after a specified benefit period, often 24 months.

Why it matters: An insurer may terminate benefits when this definition changes, even though the claimant’s medical condition has not improved.

5. Material and Substantial Duties

Definition: Material and substantial duties are the important responsibilities of an occupation that are necessary to perform the job as contemplated by the policy.

These duties may include physical activities, cognitive functions, professional judgment, communication, or other essential occupational requirements.

An insurer evaluating a disability claim may examine whether documented medical restrictions prevent the claimant from performing these duties reliably.

Why it matters: Claimants should ensure that medical and occupational evidence accurately describes their actual work responsibilities, rather than relying exclusively on a generic job title.

6. Residual Disability

Definition: Residual disability generally refers to a condition in which an insured person can continue working but experiences a qualifying reduction in occupational capacity, income, or both.

Some individual disability insurance policies provide residual disability benefits when an insured person can perform part of their occupation but cannot maintain their previous level of earnings.

The eligibility requirements and benefit formulas vary by policy.

Why it matters: A claimant who can perform some work may still qualify for partial disability benefits under certain policies.

7. Partial Disability Benefits

Definition: Partial disability benefits provide income replacement to qualifying policyholders who retain some work capacity but cannot perform their full occupational duties or earn their previous income.

Although related to residual disability, partial disability is not necessarily identical. Policies may establish different conditions, earnings thresholds, or benefit calculations.

Why it matters: Understanding partial disability coverage can be important when considering reduced working hours, modified responsibilities, or a gradual return to employment.

8. Benefit Period

Definition: The benefit period is the maximum length of time disability insurance benefits may be payable while the claimant remains eligible.

Depending on the policy, benefits may continue for a fixed period, such as two, five, or ten years, or to a stated age, such as 65 or the Social Security normal retirement age.

Certain conditions or limitations may shorten the available benefit period.

Why it matters: Knowing the benefit period is essential for long-term financial planning and understanding whether benefits could expire before retirement.

9. Monthly Benefit

Definition: The monthly benefit is the amount of disability income an insured person may receive under the policy.

Group policies commonly calculate benefits as a percentage of covered earnings, subject to maximums and possible offsets. Individual policies may provide a specified monthly amount.

Why it matters: The amount ultimately paid may differ from the policy’s stated benefit because of income calculations, other benefits, or contractual limitations.

10. Benefit Offset

Definition: A benefit offset is a reduction in disability insurance payments based on other income or benefits received by the claimant.

Depending on the policy, offsets may apply to Social Security Disability Insurance, workers’ compensation, certain retirement benefits, or income from other sources.

For example, an insurer paying $4,000 per month might reduce that payment if the policy permits an offset for a claimant’s Social Security disability benefits.

Why it matters: Offsets may substantially change the amount of income a claimant actually receives. The precise policy language determines which payments may be deducted and how those deductions are calculated.

11. Social Security Disability Insurance (SSDI)

Definition: Social Security Disability Insurance is a federal program that provides benefits to eligible individuals who meet the Social Security Administration’s disability and work-credit requirements.

SSDI differs from private long-term disability insurance. The Social Security Administration applies its own legal definition of disability, which generally requires an inability to engage in substantial gainful activity because of a qualifying impairment expected to last at least 12 months or result in death.

Some LTD insurers require claimants to apply for SSDI and may offset approved SSDI payments against their private disability benefits.

Why it matters: An SSDI approval does not automatically guarantee approval of a private disability insurance claim. Likewise, an SSDI denial does not necessarily establish that a claimant is ineligible for LTD benefits.

Learn more through the Social Security Administration’s disability eligibility guidance.

12. Pre-Existing Condition Exclusion

Definition: A pre-existing condition exclusion is a policy provision that may restrict coverage for disabilities associated with certain medical conditions that existed or received treatment before the insurance coverage became effective.

Policies typically establish specific look-back periods and exclusion periods.

For example, a policy may exclude certain disabilities arising during the first 12 months of coverage if the claimant received treatment for the condition during a specified period before enrollment.

Why it matters: Insurers may rely on pre-existing condition provisions to deny claims. Whether the exclusion applies depends on the exact policy language, relevant medical history, and circumstances surrounding the disability.

13. Policy Exclusion

Definition: A policy exclusion identifies circumstances, conditions, or risks that an insurance contract does not cover.

Long-term disability policies may contain exclusions involving intentionally self-inflicted injuries, certain circumstances of disability, or other specifically identified risks.

Exclusions vary significantly between policies and insurers.

Why it matters: A disability may otherwise satisfy the policy’s definition of disability but still be subject to an exclusion. The language and application of an exclusion may become central to a coverage dispute.

14. Policy Limitation

Definition: A policy limitation restricts the duration, amount, or scope of benefits available under certain circumstances.

For example, some group LTD policies contain 24-month benefit limitations for specified mental health conditions or certain conditions characterized primarily by self-reported symptoms.

These provisions are not universal, and their application depends on the actual contract.

Why it matters: An insurer may attempt to terminate benefits based on a contractual limitation even when a claimant continues to experience significant functional impairments.

15. Proof of Loss

Definition: Proof of loss refers to the documentation and information required to establish that a covered disability occurred and that the insured person qualifies for benefits.

Proof of loss may include medical records, attending physician statements, occupational information, income records, and other evidence requested under the policy.

Why it matters: Failure to submit sufficient proof of loss within applicable deadlines can delay or jeopardize a claim. Some policies also require ongoing proof of disability after benefits begin.

Medical and Vocational Terms Used in Disability Claims

16. Attending Physician Statement (APS)

Definition: An attending physician statement is a document completed by a treating medical provider describing the claimant’s diagnosis, symptoms, treatment, prognosis, and functional restrictions.

Insurance companies often request an APS during initial claims reviews and ongoing eligibility evaluations.

Why it matters: An effective physician statement should address how the claimant’s medical conditions interfere with specific occupational duties. A diagnosis without meaningful functional information may not adequately establish disability.

17. Residual Functional Capacity (RFC)

Definition: Residual functional capacity describes the work-related physical and mental activities an individual can perform despite medically supported impairments.

An RFC assessment may address the claimant’s ability to sit, stand, walk, lift, concentrate, interact with others, maintain attendance, and sustain activity throughout a normal workday.

Why it matters: RFC assessments can help translate medical findings into practical occupational limitations, particularly when an insurer argues that a claimant remains capable of sedentary or alternative work.

18. Independent Medical Examination (IME)

Definition: An independent medical examination is a medical evaluation arranged to assess a claimant’s condition, functional restrictions, or continuing eligibility for disability benefits.

An insurer may request an examination by a physician who does not regularly treat the claimant.

Although these examinations are called independent, the examining physician may be selected and compensated by the insurance company.

Why it matters: IME findings can significantly influence an insurer’s disability determination. Claimants should understand their policy obligations and carefully review any conclusions that conflict with their treating physicians’ findings.

19. Functional Capacity Evaluation (FCE)

Definition: A functional capacity evaluation is a structured assessment of an individual’s physical abilities and limitations.

Depending on the evaluation, an FCE may measure lifting, carrying, standing, walking, reaching, endurance, and other work-related capacities.

Why it matters: An FCE can provide useful evidence concerning physical restrictions, but its findings must be considered alongside the claimant’s overall medical history, symptoms, and occupational demands. A single evaluation may not capture fluctuating symptoms or the ability to sustain work over time.

20. Vocational Assessment

Definition: A vocational assessment evaluates an individual’s occupational skills, education, work experience, and ability to perform specific jobs in light of documented medical restrictions.

Insurers may use vocational assessments to identify occupations they believe a claimant can perform.

However, the assessment must be evaluated against the language of the policy and the claimant’s actual functional limitations.

Why it matters: A vocational assessment may become especially important when a policy transitions from an own-occupation to an any-occupation definition of disability.

Legal Terms Every Long-Term Disability Claimant Should Understand

21. Employee Retirement Income Security Act (ERISA)

Definition: The Employee Retirement Income Security Act of 1974, commonly known as ERISA, is a federal law establishing standards for many employer-sponsored retirement, health, and disability benefit plans.

ERISA governs the administration and claims procedures of many employer-provided LTD plans. However, certain plans, including governmental plans and church plans, are generally exempt, and individually purchased disability policies are typically governed by state insurance and contract law.

ERISA can affect:

• How an insurer must review a disability claim.
• The right to obtain relevant claim documentation.
• Administrative appeal procedures and deadlines.
• The process for pursuing litigation after a denial.
• Available legal remedies.

Why it matters: Determining whether ERISA applies is one of the most consequential legal questions in a disputed disability claim because it can substantially affect both procedural rights and litigation strategy.

For additional information, review the U.S. Department of Labor’s Employee Benefits Security Administration.

22. Administrative Appeal

Definition: An administrative appeal is the formal process through which a claimant asks an ERISA-governed disability plan to reconsider an adverse benefits decision.

Under federal regulations, claimants generally must be provided at least 180 days after receiving a denial notice to file an appeal.

The appeal should directly address the insurer’s stated reasons for denial and may involve submitting additional medical opinions, occupational evidence, vocational analysis, and other relevant documentation.

Why it matters: Claimants generally must exhaust required administrative remedies before pursuing an ERISA benefits lawsuit. The administrative appeal is therefore an important opportunity to establish a comprehensive evidentiary record.

The Department of Labor’s guide to filing disability benefit claims provides additional information about ERISA claim and appeal procedures.

23. Administrative Record

Definition: The administrative record is the collection of documents, evidence, correspondence, and other materials relevant to a claim reviewed through the administrative process.

It may include medical records, physician opinions, claim forms, insurer reports, vocational assessments, denial notices, and other relevant materials.

In ERISA litigation, judicial review is often primarily based on the administrative record developed before the insurer’s final decision, subject to applicable legal standards and exceptions.

Why it matters: If critical medical or occupational evidence is omitted during the administrative process, introducing that evidence later in federal court may be difficult or restricted.

24. Exhaustion of Administrative Remedies

Definition: Exhaustion of administrative remedies generally means completing the required internal claims and appeal procedures before seeking judicial review.

In many ERISA disability cases, a claimant must complete the plan’s mandatory appeal process before filing a federal lawsuit.

Exceptions or alternative rules may apply, including certain circumstances involving a plan’s failure to comply with applicable claims procedures.

Why it matters: Filing suit before satisfying applicable exhaustion requirements can create procedural complications. Conversely, pursuing unnecessary voluntary appeals may affect litigation strategy and timing.

25. Standard of Review

Definition: The standard of review is the legal framework a court uses when evaluating an insurer’s disability benefits determination.

Two important standards in ERISA litigation are:

• De novo review: The court independently evaluates whether the claimant is entitled to benefits under the plan, without deferring to the administrator’s benefit determination.
• Abuse of discretion review: The court gives a degree of deference to the administrator’s decision when the plan validly grants discretionary authority, subject to applicable law.

The standard depends on several factors, including governing plan language, controlling judicial precedent, and potentially applicable state restrictions on discretionary clauses.

Why it matters: The applicable standard of review can materially influence how a court assesses the insurer’s reasoning and the claimant’s entitlement to benefits.

26. Claim Denial

Definition: A claim denial occurs when an insurer or plan administrator determines that an applicant has not established entitlement to disability benefits under the applicable policy or plan.

Common reasons cited in denial letters include insufficient medical evidence, failure to satisfy the definition of disability, policy exclusions, and alleged ability to perform occupational duties.

For ERISA-governed plans, denial notices must generally identify the specific reasons for the adverse decision, relevant plan provisions, and applicable review procedures.

Why it matters: A denial is not necessarily the final determination of a claimant’s rights. Understanding the insurer’s stated reasons and applicable deadlines is essential when evaluating the next steps.

27. Claim Termination

Definition: Claim termination occurs when an insurer stops paying disability benefits after previously approving the claim.

An insurer may terminate benefits based on an asserted improvement in medical condition, a change in the policy’s disability definition, expiration of a benefit limitation, or a determination that continuing eligibility requirements have not been satisfied.

Why it matters: Prior approval does not guarantee that disability benefits will continue indefinitely. Claimants should closely examine the insurer’s explanation for termination, the supporting evidence, and their available rights to challenge the decision.

28. Insurance Bad Faith

Definition: Insurance bad faith generally refers to unreasonable or unlawful conduct by an insurer in investigating, evaluating, denying, delaying, or handling an insurance claim.

Depending on state law and the circumstances, bad faith may involve an unreasonable refusal to pay covered benefits, failure to conduct an appropriate investigation, or improper handling of a legitimate claim.

State-law bad faith remedies are especially relevant to many individually purchased disability insurance policies. ERISA generally preempts state-law bad faith claims involving benefits under covered employee benefit plans.

Why it matters: When applicable state law permits a bad faith claim, certain additional remedies may be available beyond unpaid contractual benefits. The requirements and remedies vary by jurisdiction.

29. ERISA Litigation

Definition: ERISA litigation is a legal action involving rights or benefits under an ERISA-governed employee benefit plan.

Under Section 502(a)(1)(B) of ERISA, an eligible participant or beneficiary may bring a civil action to recover benefits due under the plan, enforce rights under its terms, or clarify rights to future benefits.

ERISA cases are commonly litigated in federal court, although state courts have concurrent jurisdiction over certain benefits actions.

Why it matters: ERISA litigation differs substantially from many traditional insurance lawsuits. Available remedies, evidentiary procedures, and judicial review standards can be more restrictive than those available under state law.

The governing federal statute is available through 29 U.S.C. § 1132, ERISA’s civil enforcement provision.

30. Statute of Limitations

Definition: A statute of limitations is a legal deadline for filing a lawsuit.

The applicable filing period for a disability benefits dispute depends on the type of policy, governing law, and relevant contractual provisions.

Some ERISA plans contain enforceable contractual limitations periods, while other disputes may be governed by statutory deadlines.

Why it matters: Missing an applicable litigation deadline can prevent a claimant from pursuing judicial relief, regardless of the underlying merits of the claim.

Claimants should not assume that the deadline to submit an internal appeal is the same as the deadline to file a lawsuit.

Why Understanding Disability Insurance Terminology Matters

Disability insurance disputes frequently involve more than establishing that an individual has a serious medical condition.

Insurance companies evaluate claims using contractual definitions, documented functional limitations, occupational requirements, policy exclusions, and applicable legal standards.

A misunderstanding of these provisions can have lasting consequences.

For example, a claimant may believe that an approved LTD claim guarantees benefits through retirement. However, a change from an own-occupation definition to an any-occupation standard could lead to a new eligibility evaluation.

Similarly, an individual challenging an ERISA denial may not realize that the evidence submitted during the administrative appeal can substantially influence any future litigation.

Understanding the terminology helps policyholders identify important questions, review insurer communications more effectively, and make informed decisions when benefits are delayed, denied, or terminated.

What Should You Do If Your Long-Term Disability Claim Is Denied?

Receiving a denial or termination letter does not necessarily mean that you are ineligible for disability benefits.

The appropriate response depends on your policy, applicable laws, the insurer’s stated reasons, and the evidence supporting your disability.

Claimants should promptly:

1. Review the denial letter and policy provisions. Identify the specific reasons for the insurer’s determination and the provisions it relied upon.
2. Determine whether ERISA applies. Employer-sponsored and individually purchased policies can involve significantly different procedures and remedies.
3. Identify all applicable deadlines. Review the dates for administrative appeals, contractual limitations periods, and potential litigation.
4. Obtain relevant claim documentation. For ERISA-governed claims, federal regulations provide important rights to relevant records and information.
5. Evaluate the medical and occupational evidence. Determine whether the insurer accurately considered the claimant’s restrictions and the material duties of the relevant occupation.
6. Consult an experienced disability insurance attorney. Legal guidance can help identify disputed policy provisions, evidentiary deficiencies, and available options before important deadlines expire.

The U.S. Department of Labor provides additional guidance concerning ERISA protections for employee benefit plans.
