Disability insurance replaces a portion of income when a worker cannot work due to illness or injury. In the United States, it is split into two categories — short-term disability (STD) and long-term disability (LTD) — with different waiting periods, benefit periods, and policy structures. Worker understanding of the two tends to be limited, and the consequences of a coverage gap can be significant: a serious disability claim without adequate coverage often produces financial hardship.

This article walks through the distinctions and the terms in a typical disability policy that most affect a claim. It is not insurance advice. The Social Security Disability program is a separate federal benefit that stacks with private disability insurance; the SSA disability page is the starting reference for that program.[¹]

Short-term disability (STD)

Short-term disability covers a relatively brief period of disability — typically 3 to 6 months, sometimes up to 12 months.

Typical STD features:

• Waiting period (elimination period). Often 7 to 14 days after the onset of disability before benefits begin. During the waiting period the worker uses sick leave, PTO, or other paid leave.
• Benefit percentage. Typically 60 to 70 percent of pre-disability income, often capped at a weekly dollar amount.
• Benefit period. Usually 13 or 26 weeks, depending on the policy.
• Definition of disability. Most STD policies use a broader definition — the worker is disabled if unable to perform the material duties of their own occupation.

STD is frequently employer-provided through a group insurance plan. Some states (California, New Jersey, New York, Rhode Island, Hawaii) also run state-administered short-term disability programs that substitute for or supplement private STD.

Long-term disability (LTD)

Long-term disability covers extended disability, often through to retirement age. Typical LTD features:

• Waiting period. Typically 90 to 180 days after the onset of disability, aligned to end when STD benefits (if any) end.
• Benefit percentage. Typically 50 to 60 percent of pre-disability income, capped at a monthly dollar amount.
• Benefit period. Commonly until age 65 or 67, or a stated number of years (2, 5, 10 years) depending on the policy.
• Definition of disability. LTD policies vary — "own occupation" definitions last for a stated period (usually 24 months), after which the definition typically switches to "any occupation for which the insured is reasonably suited."

The "own occupation" vs "any occupation" distinction is the single most important term in an LTD policy. Own-occupation coverage continues to pay if the insured cannot perform their specific profession — a surgeon who develops a hand tremor and can no longer perform surgery is disabled under own-occupation even if they could work as a medical consultant. Any-occupation coverage ends when the insured could work in any reasonably-compensated position — the same surgeon might be denied any-occupation benefits because they could teach or consult.

Group vs individual policies

Disability insurance comes in two main delivery channels:

• Group policies. Sold to employers, who extend coverage to employees. Coverage is typically automatic for full-time employees up to a specified amount; additional coverage may be available through voluntary buy-up options. Group LTD is governed by ERISA for private-sector employers.[²]
• Individual policies. Purchased directly from an insurer. Individually underwritten based on the insured's occupation, age, health, and income. More customisable; typically portable if the insured changes employers.

Group policies tend to be cheaper per dollar of coverage but are less customisable and end when the insured leaves the employer. Individual policies are more expensive but portable and typically have stricter definitions of disability from the insurer's perspective, which usually favours the insured at claim time.

Many high-income professionals — physicians, attorneys, executives — supplement group LTD with an individual policy to close the gap between the group benefit cap and their actual income.

Taxation

The tax treatment of disability benefits depends on how the premium was paid:

• Employer-paid premium, pre-tax. Benefits are taxable when received.
• Employer-paid premium, included in the employee's W-2 income. Benefits are typically tax-free.
• Employee-paid premium, after-tax. Benefits are typically tax-free.

An employee who receives $5,000 per month in taxable LTD benefits keeps less after tax than an employee receiving $5,000 per month in tax-free benefits. When comparing group policies against individual policies, the after-tax benefit is the number that matters for replacement-income adequacy.

Definition of disability — the detail that drives claims

Beyond own-occupation vs any-occupation, LTD policies vary in several further ways:

• Residual or partial disability. Does the policy pay reduced benefits while the insured is working part-time or in a different role at reduced income? Residual coverage is typically a better feature than total-only coverage.
• Mental-nervous conditions. Many LTD policies cap benefits for mental, nervous, or substance-abuse conditions at 24 months. A mental-health condition that extends beyond the cap may not continue to pay benefits under the policy.
• Pre-existing condition exclusion. New policies often exclude disabilities that begin within a stated look-back period (3 to 12 months) from a pre-existing condition. A condition that was active at policy inception may trigger the exclusion.
• Concurrent-cause provisions. If a disability has both a covered cause (e.g., back injury) and a partially-excluded cause (e.g., mental-health condition), how does the policy pay?
• Social Security offset. Many group LTD policies reduce benefits by the amount of Social Security Disability Insurance (SSDI) the insured receives.

The NAIC glossary has a single entry per term for readers new to the vocabulary.[³]

State programs

Five states run state-administered short-term disability (SDI) programs:

• California — State Disability Insurance (SDI) administered by EDD.
• New Jersey — Temporary Disability Insurance (TDI) administered by the Department of Labor.
• New York — Disability Benefits Law (DBL) administered by the Workers' Compensation Board.
• Rhode Island — Temporary Disability Insurance (TDI) administered by the Department of Labor.
• Hawaii — Temporary Disability Insurance (TDI).

These programs typically replace a portion of wages for short-term disabilities that are not work-related (work-related disabilities are covered by workers' compensation). Funding varies — some states fund through employee payroll deductions, others through employer contributions.

An employee in one of these states usually does not need a separate STD policy; the state program provides short-term coverage, and private LTD picks up at the end of the state benefit period.

Federal Social Security Disability Insurance (SSDI)

SSDI is a federal program administered by the Social Security Administration. Eligibility requires:

• Sufficient work history (generally 40 quarters of Social Security-covered work, with recency requirements).
• A disability expected to last at least 12 months or result in death.
• Inability to engage in "substantial gainful activity" considering age, education, and work experience.

SSDI benefits begin after a five-month waiting period. The benefit amount is based on the insured's earnings history, averaging around $1,500 per month for most recipients in 2024 dollars.[¹]

SSDI has a much stricter definition of disability than most private LTD policies — many private LTD claimants do not qualify for SSDI, which is one reason private LTD insurance exists.

Claim filing mechanics

When a disability occurs:

1. Notify the employer (for group) or the individual insurer promptly — typically within 30 days.
2. Request and complete the claim forms, which include an insured statement, an attending-physician statement, and an employer statement (for group).
3. Provide supporting medical records and any income documentation the insurer requests.
4. Comply with any independent medical examination (IME) requested by the insurer.
5. Apply for SSDI if the LTD policy requires or offsets against it.

Claim denials are appealed internally (through the insurer's claim process) and — for ERISA-governed group plans — potentially in federal court after exhausting internal appeals. The ERISA remedy set is limited in ways that may surprise claimants; the DOL's ERISA resource is the starting point.[²]

What to read carefully in a policy

Key policy terms to understand:

• The waiting period.
• The benefit percentage and monthly dollar cap.
• The benefit period (to age 65, to age 67, 2/5/10 years).
• The own-occupation vs any-occupation definition and the duration of the own-occupation period.
• The mental-nervous limitation (typically 24 months).
• The pre-existing condition exclusion.
• The Social Security offset.
• The residual/partial disability provision.
• The cost-of-living adjustment (COLA), if any.
• Renewal or continuation rights.

Where DocAssessment fits

DocAssessment extracts disability insurance policy declarations and the key policy provisions deterministically before any AI model sees the document. The methodology page describes the seven-step pipeline. For a disability policy specifically, the extraction surfaces the benefit percentage, waiting period, benefit period, and the own-vs-any occupation language, and flags common gaps (missing residual coverage, short own-occupation period, or a significant Social Security offset).

For specific questions about an individual's coverage adequacy, an insurance professional or fee-only financial planner typically is the appropriate next step. For a disputed claim, an ERISA or disability-insurance attorney often is warranted.
