If MetLife has denied your disability claim, you're dealing with two separate systems at once — and most people don't realize that until they're already frustrated. MetLife administers employer-sponsored group disability insurance, which runs under federal rules called ERISA. That's entirely separate from Social Security Disability Insurance (SSDI), which is run by the Social Security Administration. A denial from MetLife does not automatically affect your SSDI claim — but the two can intersect in ways that matter.
MetLife is a private insurer. When your employer offers short-term or long-term disability (LTD) coverage, MetLife is often the company processing those claims. Their decisions are governed by your plan documents and by ERISA — the Employee Retirement Income Security Act — not by SSA rules.
SSDI, by contrast, is a federal entitlement program funded through payroll taxes. It's administered by the SSA and evaluated by state-level Disability Determination Services (DDS) agencies. The standards, definitions, and appeal paths are completely different.
| Feature | MetLife LTD | SSDI |
|---|---|---|
| Administered by | MetLife (private insurer) | Social Security Administration |
| Governing law | ERISA / plan documents | Social Security Act |
| Definition of disability | Often "own occupation" then "any occupation" | Inability to do any substantial gainful work |
| Appeal process | Internal appeal → federal lawsuit | Reconsideration → ALJ → Appeals Council → federal court |
| Benefit amount | Percentage of pre-disability earnings | Based on your lifetime earnings record |
MetLife denials follow patterns. Common stated reasons include:
The specific reason matters because it shapes what kind of appeal has any chance of succeeding.
Under ERISA, you generally have a right to at least one internal administrative appeal before you can sue in federal court. This is not optional — if you skip the internal appeal, you typically lose your right to litigate later.
Key features of ERISA appeals:
If the internal appeal is also denied, your remaining option is generally to file suit in federal district court — which is a slower, more expensive path with limited discovery rights.
Here's where it gets complicated. If you're disabled enough to be fighting a MetLife LTD claim, you may also be eligible for SSDI — and the two interact in several ways:
Offset provisions. Most group LTD policies contain an SSDI offset clause. If you're approved for SSDI, MetLife will reduce your LTD benefit by the amount of your SSDI payment. This is legal and standard. Some claimants are surprised to find that their total income doesn't increase much when SSDI kicks in.
MetLife may require you to apply for SSDI. Many policies require claimants to apply for SSDI as a condition of receiving LTD benefits. If you refuse, MetLife may reduce your benefit as if you'd been approved anyway.
An SSA approval doesn't bind MetLife. The SSA uses its own definition of disability. Being approved for SSDI does not guarantee MetLife will approve or reinstate your LTD claim — though a favorable SSA decision can strengthen your administrative record.
An SSA denial doesn't end your SSDI options. The SSDI appeals process runs through reconsideration → ALJ hearing → Appeals Council → federal court. Most successful SSDI claims are won at the Administrative Law Judge (ALJ) hearing stage, not on initial application. Approval rates at the ALJ level are significantly higher than at the initial determination stage.
Whether a MetLife appeal or SSDI claim succeeds depends heavily on specifics that vary from person to person:
The mechanics of MetLife denials, ERISA appeals, and SSDI applications are knowable. The process is documented. Timelines exist. Rules can be studied.
What can't be assessed from the outside is how your specific medical records, your plan's exact definition of disability, your earnings history, and your functional limitations combine in your particular case. Two people with the same diagnosis, the same insurer, and the same employer can face completely different outcomes — because the details that determine results aren't visible in the rules alone.
That's the piece only your situation can fill in.
