If you've been denied long-term disability (LTD) benefits and someone mentioned getting a lawyer, you may be hearing two separate legal tracks discussed at once. Understanding how they overlap — and where they split — matters before you take your next step.
Long-term disability (LTD) is private insurance — either purchased individually or provided through an employer. It's governed by your specific policy and, if employer-sponsored, by a federal law called ERISA (Employee Retirement Income Security Act). The Social Security Administration has nothing to do with it.
SSDI (Social Security Disability Insurance) is a federal program administered by the SSA. Eligibility depends on your work history (measured in work credits), your medical condition, and whether that condition prevents you from performing substantial gainful activity (SGA) — a specific earnings threshold that adjusts annually.
Attorneys who handle denied LTD claims and attorneys who handle denied SSDI claims often work in overlapping spaces — but the legal rules, appeal processes, and strategies are different.
Private LTD policies deny claims for a range of reasons:
When an LTD claim is employer-sponsored, the denial appeal process is typically governed by ERISA, which has strict deadlines and limits the evidence you can introduce later if you go to court. This is one reason attorneys experienced in LTD denials emphasize acting quickly and thoroughly at the administrative appeal stage.
Here's where many claimants get tangled: LTD insurers often require you to apply for SSDI as a condition of receiving LTD benefits. If SSA approves your SSDI claim, the LTD insurer typically offsets (reduces) your LTD benefit by the SSDI amount.
This means:
Understanding which fight you're in — or whether you're in both — shapes everything about legal strategy.
When SSA denies an SSDI application, you have the right to appeal through a structured process:
| Stage | What Happens | Typical Timeframe |
|---|---|---|
| Initial Application | DDS reviews medical and work evidence | 3–6 months |
| Reconsideration | A fresh DDS review of the denial | 3–5 months |
| ALJ Hearing | In-person or video hearing before an Administrative Law Judge | 12–24+ months |
| Appeals Council | Internal SSA review of ALJ decision | Months to over a year |
| Federal Court | Civil lawsuit challenging SSA's final decision | Varies widely |
Most successful SSDI appeals happen at the ALJ hearing stage. That's also where legal representation tends to make the most practical difference — preparing medical evidence, developing the residual functional capacity (RFC) argument, and cross-examining vocational experts.
SSDI attorneys typically work on contingency, meaning they collect a fee only if you win. That fee is capped by federal law at 25% of back pay, up to a statutory maximum that adjusts periodically.
Whether you're fighting an LTD denial, an SSDI denial, or both, several variables drive the result:
Medical evidence — The strength, consistency, and specificity of records from treating physicians carries enormous weight. Vague diagnoses or gaps in treatment can sink claims at every level.
Onset date — In SSDI, your alleged onset date (AOD) determines how much back pay you may be owed. An earlier onset with supporting documentation can significantly increase the total amount at stake.
Work history — SSDI requires sufficient work credits, earned through recent employment. LTD claims turn on your specific policy terms and employment classification.
Application stage — Whether you're at initial denial, reconsideration, ALJ, or federal court determines which rules apply and what evidence is still admissible.
Policy language (for LTD) — The difference between "own occupation" and "any occupation" definitions in an LTD policy can determine whether you qualify at all after the first two years of disability.
State and jurisdiction — Federal courts that review ERISA LTD denials and SSA decisions can vary in how they interpret evidence standards and procedural rules.
Someone denied LTD benefits due to a documentation gap has a different path than someone denied after an independent medical exam contradicts their surgeon's findings. A person denied SSDI at initial application with a strong RFC argument faces different considerations than someone whose ALJ hearing was decided on a vocational expert's testimony about available jobs.
In cases involving both denials simultaneously, timing becomes critical — the ERISA administrative record for the LTD appeal may close before a federal case is filed, locking in whatever evidence exists at that moment.
People with employer-sponsored LTD plans who are also pursuing SSDI sometimes find that coordinating both claims — even with separate attorneys — requires active communication to avoid decisions in one proceeding that undercut the other.
The rules governing LTD denials, SSDI appeals, and how the two interact are well-established. What they look like applied to a specific claimant — your policy language, your medical records, your work credits, your appeal stage, and your particular denial reason — is something no general explanation can answer. That's the gap between understanding the landscape and knowing where you actually stand in it.
