TL;DR: MetLife is a third-party administrator that many employers hire to process FMLA and disability claims on their behalf, but MetLife doesn't create or change your federal FMLA rights, it just handles the paperwork and the medical review. You typically file through MetLife's MyBenefits portal or by phone, then your healthcare provider submits certification, usually within 15 days. MetLife reviews the medical documentation and coordinates the FMLA designation with your employer, but your underlying eligibility still comes from the Family and Medical Leave Act itself. If MetLife denies part of your claim, your appeal path depends on exactly what was denied. Here's how the process works, and where MetLife's role stops and your employer's legal obligations begin.
If your pay stub or benefits card says MetLife, your employer has outsourced leave and disability claims administration to them instead of handling it in-house through HR. That's common, MetLife is one of the largest group disability and absence-management carriers in the country. It agrees with what most people assume: filing through a third party feels confusing, and it's not always clear whether MetLife or your employer is actually the one deciding your fate. This guide breaks down exactly what MetLife does and doesn't control, how to actually file a claim, what happens after you submit it, and, critically, how the process connects back to the FMLA rights you already have under federal law regardless of who's processing the paperwork.
What MetLife Actually Does (and Doesn't Do)
MetLife is a claims administrator, not a lawmaker. Your employer hires MetLife to intake leave requests, collect medical certification, track your leave usage, and often to administer a paired short-term disability policy at the same time. What MetLife does not do is change the Family and Medical Leave Act. The law's three-part eligibility test, 12 months employed, 1,250 hours worked in the trailing 12 months, and an employer with 50 or more employees within 75 miles, comes from federal statute and Department of Labor regulations, not from MetLife's internal rules. See our full breakdown in FMLA eligibility: who qualifies and how to check.
Your employer remains the "employer" for FMLA purposes even when MetLife handles the claim. That distinction matters in disputes: MetLife's own materials for its group disability and leave products describe FMLA as providing "up to 12 weeks of unpaid, job-protected leave" for employers with 50 or more employees, and MetLife positions itself as helping employers apply that federal framework, not replacing it (MetLife: Federal Programs).
How to File an FMLA Claim Through MetLife
Step 1: Tell Your Employer First
Notify your supervisor or HR that you need leave, the way you would for any FMLA request. MetLife handles claims processing, but your employer is still the one with the legal notice obligation under FMLA, telling MetLife alone, without your employer knowing, isn't a substitute.
Step 2: File the Claim
MetLife's own guide to filing a disability claim describes a portal called MyBenefits for reporting and tracking leave and disability claims, along with online claim submission and an employee ID-based reference number for tracking (MetLife: Disability Claims Guide). That same guide notes that employee groups under roughly 1,000 people may need to call in rather than self-file online, which is a useful detail, because it means the process isn't identical for every MetLife-administered employer.
MetLife assigns each employer a different phone number and sometimes a different portal address, because the "MetLife" claims experience is customized per employer group. We found at least two verified, different combinations across MetLife's own materials and employer benefits guides, a general disability-claims number on metlife.com, and separate numbers cited in individual universities' benefits documents for their own employee groups. Rather than print a single number here that might be wrong for your employer, check your benefits card, your pay stub, or your HR portal for the MetLife number and portal login tied to your specific plan.
Step 3: Provide Your Basic Information
Whichever channel you use, expect to provide your name, date of birth, Social Security number or employee ID, your employer's name, and your expected leave dates.
Step 4: Get Medical Certification Submitted
MetLife's forms library lists the standard certification forms it uses, including a "Certification for Employee's Serious Health Condition" and a "Certification for Family Member's Serious Health Condition", the same underlying content required by the DOL's WH-380-E and WH-380-F forms, just formatted on MetLife's letterhead (MetLife Forms Library). Across MetLife's own materials and multiple employer benefits guides, the consistent instruction is to have your healthcare provider complete and return certification within 15 calendar days, the same deadline the FMLA regulations themselves set for medical certification generally.
Step 5: Wait for a Determination
MetLife doesn't publish a fixed, universal processing-time guarantee on its public site, so treat any specific "5 business days" or "10 business days" claim you see elsewhere with skepticism unless it comes from your own plan documents. What is documented: MetLife mails an acknowledgment packet after you file, and you can track status, upload documents, and receive email or text alerts through MyBenefits rather than waiting on a phone call (MetLife: Disability Claims Guide).
MetLife's FMLA Designation vs. Your Employer's Obligation
Here's the part that trips people up: MetLife can review your medical certification and make a recommendation, but the FMLA designation notice, the official confirmation that your leave counts as FMLA-protected, is ultimately an employer obligation under DOL rules. In practice, when an employer outsources claims to MetLife, MetLife typically issues that designation notice on the employer's behalf, using the same content the DOL's Form WH-381 would contain. But legally, your employer can't escape responsibility for FMLA compliance just by pointing at a vendor. If MetLife mishandles your claim, loses paperwork, misapplies the eligibility test, or drags out a determination past a reasonable point, that's still your employer's problem to fix, because the statute puts the obligation on the employer, not on whichever company they hired to process the intake form. Our guide to FMLA and short-term disability covers how the concurrent designation process is supposed to work regardless of which administrator is involved.
MetLife and Short-Term Disability: How the Two Claims Relate
Many employers that use MetLife for FMLA administration also use MetLife to insure short-term disability (STD), a separate, paid benefit that replaces part of your wages while you're medically unable to work. FMLA and STD are legally distinct: FMLA protects your job and is unpaid by default; STD pays you a percentage of wages but carries no job-protection guarantee of its own. When both run through MetLife, they typically move in parallel, the same medical certification often supports both claims, but they're evaluated against different standards (FMLA's eligibility test vs. Your specific STD policy's definition of disability), and one being approved doesn't guarantee the other will be. File both, and don't assume approval of one settles the other. See FMLA and short-term disability: how they work together for the full mechanics of how the two run concurrently.
If MetLife Denies Your Claim
This is where it matters a lot which claim got denied, because the appeal rules are genuinely different.
If your short-term disability claim was denied: Employer-sponsored group disability plans are typically governed by ERISA, the federal law covering most employee benefit plans. Under ERISA's claims regulations, plan administrators generally have 45 days to decide a disability claim, with one possible 45-day extension for special circumstances, and claimants generally have up to 180 days from the date of a denial letter to file a formal internal appeal (29 CFR § 2560.503-1). Missing that window can permanently forfeit your right to challenge the decision, so read your denial letter's deadline carefully rather than relying on a generic number, plan terms vary.
If your FMLA designation was denied or your leave wasn't recognized as FMLA: That's a different legal track entirely. FMLA disputes aren't ERISA benefit claims, they're enforced through the Department of Labor's Wage and Hour Division or through a private lawsuit. Under 29 U.S.C. § 2617(c), you generally have two years from the last violation to bring an FMLA claim, or three years if the violation was willful. You don't have to exhaust an internal appeal with MetLife first to preserve those rights, though asking MetLife what specific documentation was missing is still the fastest way to get an initial denial reversed without escalating. Use our FMLA forms finder to make sure you're submitting the right federal documentation alongside whatever MetLife-branded version you were given.
Frequently Asked Questions
Does MetLife decide whether I qualify for FMLA?
Not entirely on its own. MetLife reviews your medical certification and processes the claim, but FMLA eligibility itself, 12 months employed, 1,250 hours worked, and an employer with 50+ employees within 75 miles, is defined by federal law, and your employer remains legally responsible for FMLA compliance even when MetLife handles the paperwork.
How do I file an FMLA claim through MetLife?
Notify your employer first, then file through MetLife's MyBenefits portal or by calling the MetLife number tied to your specific employer's plan (check your benefits card, pay stub, or HR portal, since MetLife assigns different contact numbers per employer group). You'll need your name, employer, Social Security number or employee ID, and expected leave dates.
What phone number do I call for MetLife FMLA claims?
There isn't one universal number. MetLife issues a different phone number and portal login to each employer group it administers claims for. Look for the specific MetLife contact information on your benefits enrollment materials, pay stub, or your company's HR/benefits portal rather than relying on a number from an unrelated employer's guide.
How long does MetLife take to process an FMLA claim?
MetLife hasn't published a fixed universal turnaround time for FMLA determinations on its public site. What is consistent across MetLife's own materials is a 15-calendar-day window for your healthcare provider to return completed medical certification, the review clock generally doesn't meaningfully start until MetLife has that documentation in hand.
Does MetLife handle both FMLA and short-term disability?
For many employers, yes. They're separate claims evaluated under different standards, so file both if you need both, and don't assume one approval guarantees the other. See our guide to how FMLA and short-term disability work together.
What if MetLife denies my short-term disability claim?
Employer-sponsored disability plans are typically governed by ERISA, which generally gives you up to 180 days from your denial letter to file a formal internal appeal, and generally requires the administrator to decide within 45 days (extendable once by another 45 days for special circumstances). Check your specific denial letter for your plan's exact deadline.
What if MetLife says my leave isn't FMLA-qualifying?
Ask specifically what was missing from your certification, incomplete medical paperwork is the most common reason for an initial denial, and often fixable by having your doctor complete the form more fully. If you believe the denial is wrong on the merits, you can pursue it as a federal FMLA matter through the Department of Labor's Wage and Hour Division or a private lawsuit, separate from any MetLife-specific appeal process.
How long do I have to dispute an FMLA denial?
Under 29 U.S.C. § 2617(c), you generally have two years from the last FMLA violation to bring a claim, or three years if the violation was willful. This federal statute of limitations applies regardless of which company administered your employer's claim.
Can my manager overrule MetLife's FMLA determination?
Generally no in either direction, your manager doesn't have authority to approve or deny FMLA on their own once a leave administrator is involved, but your employer as a whole still bears ultimate legal responsibility for FMLA compliance, even when MetLife processes the claim on their behalf.
Do I need a doctor's note to file through MetLife?
Yes. MetLife's certification forms require your healthcare provider to complete the medical portion, diagnosis or condition, when it began, expected duration, and functional limitations, mirroring the content required by the DOL's own WH-380-E and WH-380-F forms.
Is MetLife the same as my employer's HR department?
No. MetLife is a third-party vendor your employer contracts with to administer leave and disability claims. HR still handles your employment relationship directly, scheduling, job protection enforcement, and return-to-work logistics, even though MetLife handles the claims intake and medical review.
What should I do if I can't reach MetLife or my portal login isn't working?
Contact your employer's HR or benefits team first, they can usually confirm the correct MetLife contact number and portal for your specific plan, since these details vary by employer group rather than being the same for every MetLife-administered company.
Key Takeaways
MetLife administers claims, it doesn't rewrite the law. Your FMLA eligibility still comes from the federal statute: 12 months employed, 1,250 hours worked, 50+ employees within 75 miles.
File through MyBenefits or by phone, but get your employer-specific contact details from your own benefits materials. MetLife assigns different numbers and portals per employer group.
Medical certification is generally due within 15 calendar days of your provider receiving the form.
FMLA and short-term disability are separate claims with separate standards, even when both run through MetLife.
Appeal paths differ by claim type: disability denials generally follow ERISA's roughly-180-day internal appeal window; FMLA disputes go through the DOL or courts, with a 2-year (3-year if willful) statute of limitations under 29 U.S.C. § 2617(c).
Your employer stays responsible for FMLA compliance, even when MetLife handles the paperwork.
