TL;DR: The Hartford is a private insurance company that many large employers hire to administer FMLA and disability leave claims. It processes your paperwork and makes the leave-designation call on your employer's behalf, but it can't shrink or expand your underlying federal FMLA rights, those come from the statute, not from The Hartford's internal process. File your claim through your employer's Hartford benefits portal (commonly TheHartford.com/mybenefits) or by phone using the number in your benefits guide, since The Hartford doesn't run one universal FMLA line, the number depends on your employer's specific plan. Here's exactly how the process works, and what to do if a claim gets denied or stalls.
Getting a leave letter from an insurance company instead of your own HR department feels strange, like your medical situation just became someone else's business decision. It hasn't, not really. This guide walks through what The Hartford actually does when it's handling your FMLA claim, how to file, what information to have ready, how The Hartford's role fits together with short-term disability, and, most importantly, how the federal law underneath all of it still applies no matter what a claims adjuster decides.
What Is The Hartford, and Why Is It Handling Your FMLA Claim?
The Hartford (Hartford Financial Services Group) is one of the largest group benefits insurers in the US, selling disability, life, and absence-management products to employers. When a company doesn't want its own HR staff logging leave requests, tracking certifications, and calculating return-to-work dates, it pays The Hartford to do that instead. The Hartford calls this line of business absence management, and it markets a proprietary platform that connects to an employer's payroll and HR systems so leave data, pay, and job protection stay in sync (The Hartford, Absence Management).
This makes The Hartford a third-party administrator (TPA), not a government agency. It doesn't write FMLA law and it can't override it. The Family and Medical Leave Act is a federal statute enforced by the US Department of Labor's Wage and Hour Division (dol.gov/agencies/whd/fmla). The Hartford's job is to apply that law (plus your employer's specific plan rules) to your individual claim. If The Hartford gets a determination wrong, your legal FMLA rights don't disappear; you can still push back through your employer, the DOL, or an attorney.
How to File an FMLA Claim Through The Hartford
Step 1: Tell Your Employer First
Notify your manager or HR that you need leave. This isn't optional paperwork, it's usually the trigger that gets you the correct Hartford intake number and policy information for your specific employer.
Step 2: Contact The Hartford
There's no single Hartford FMLA phone number that works for every employee, the intake line and even the portal address are set per employer contract, so check your benefits guide or your HR portal for the exact number. Across employer benefit pages, the most consistently cited entry point is TheHartford.com/mybenefits, which is also referenced directly on The Hartford's own employee benefits claims page (The Hartford, Employee Benefits Claims). Have this ready when you call or log in:
Your name, employer, and employee ID
Your policy or claim number, if you have one
The reason for leave and your last full day of active work
Your treating provider's name, address, phone, and fax number
Step 3: Give Notice on Time
If your leave is foreseeable (a scheduled surgery, an expected birth) federal regulations require you to give your employer at least 30 days' notice when possible (29 C.F.R. § 825.302). If it's not foreseeable, notify The Hartford and your employer as soon as you reasonably can. This isn't a Hartford-specific rule; it's baked into the FMLA regulations themselves, and Hartford-administered plans follow it.
Step 4: Complete the Medical Certification
The Hartford (or your employer) issues the certification form; your healthcare provider fills out the medical portion. Federal regulations give you at least 15 calendar days to return a complete certification once it's requested (29 C.F.R. § 825.305). Missing that window is one of the most common reasons a leave gets delayed rather than denied outright, a form with blank fields gets kicked back for clarification, which restarts the clock.
Step 5: Wait for a Determination
The Hartford doesn't publish a guaranteed universal turnaround time for FMLA determinations, so don't assume a specific number of days, it depends on your employer's plan and how quickly your provider's paperwork comes back complete. What's certain either way: the clock on your 12 weeks of protected leave generally starts running once your leave qualifies as FMLA, not once The Hartford finishes paperwork, so don't wait passively, follow up if you haven't heard anything within a couple of weeks.
In 2024, The Hartford announced two tools built into its absence platform: Leave Lens, described as a resource to help employers and employees understand and navigate leave planning, and an Absence Dashboard for tracking claims (The Hartford investor relations, press release). The Hartford also markets a "single advocate" model, meaning one representative is meant to stay assigned to your claim rather than routing you through a general call queue each time you follow up.
What that means practically: your point of contact, your online status portal, and the exact tools available to you depend on what your specific employer purchased. Some employers get the full dashboard experience; others get a more bare-bones phone-and-mail process. If you're not sure which you have, your HR department (not The Hartford's marketing pages) is the fastest way to find out.
The Hartford Doesn't Change Your Federal FMLA Rights
This is the part worth repeating: whatever The Hartford's internal process looks like, the FMLA entitlement underneath it is fixed by federal law, not by any insurance company's discretion.
Up to 12 weeks of job-protected leave in a 12-month period for your own serious health condition, a new child, or to care for a spouse, child, or parent with a serious health condition
Up to 26 weeks in a single 12-month period to care for a covered servicemember with a serious injury or illness (military caregiver leave)
Unpaid. FMLA itself guarantees job protection, not a paycheck; any wage replacement comes from a separate benefit like short-term disability or state paid leave
Eligibility requires roughly 12 months of employment with your employer, at least 1,250 hours worked in the 12 months before your leave starts, and a worksite with 50 or more employees within 75 miles
Job protection means your employer must restore you to your same job or an equivalent one (same pay, benefits, and terms) when your leave ends
FMLA has been federal law since it was signed in February 1993 and took effect in August 1993; it hasn't been repealed or replaced since (dol.gov/agencies/whd/fmla). If The Hartford tells you that you don't qualify, that's their read of your specific facts against this test, not a different, lesser standard. If you think the read is wrong, you can push back. See our full FMLA eligibility guide to check the three-part test yourself before you accept a denial at face value.
The Hartford and Short-Term Disability: How They Interact With FMLA
The Hartford is also one of the largest carriers of group short-term and long-term disability insurance in the country, and multiple large employers use it for both leave administration and disability coverage at once (documented, for example, in employer benefit guides describing Hartford-managed short-term and long-term disability programs). Where that's the case, FMLA and STD are still two legally distinct things running on the same calendar:
FMLA protects your job. It's a federal right, and it's unpaid by itself.
STD is an insurance benefit that replaces a portion of your wages while you're out. The exact percentage, waiting period, and maximum benefit are set by your employer's specific policy. The Hartford doesn't publish one number that applies to every plan, so check your plan document rather than assuming a figure.
If your employer uses The Hartford for both, file both claims, approval for one doesn't automatically trigger the other, even though they usually run concurrently. For a deeper look at how wage replacement fits around unpaid FMLA leave generally, see our guide to getting paid during FMLA.
If The Hartford Denies or Delays Your FMLA Claim
Start by calling and asking exactly what's missing or why the claim was denied, incomplete certification is the most common fixable reason. Ask your provider to correct or supplement the paperwork and resubmit. Your determination letter should state your plan's specific appeal window; some Hartford-administered plans build in an appeal period, but the exact deadline is set by your employer's plan, not a single Hartford-wide rule, so read the letter rather than assuming a number.
If you believe the denial conflicts with your actual federal FMLA rights (not just your employer's internal policy) you can file a complaint with the DOL's Wage and Hour Division or consult an employment attorney. Retaliation for requesting or taking FMLA leave, including being fired, demoted, or discouraged from filing, is itself a separate FMLA violation you can report.
Frequently Asked Questions
Is The Hartford a government agency?
No. The Hartford is a private insurance company. Employers hire it to administer leave and disability claims, but the Family and Medical Leave Act itself is federal law enforced by the US Department of Labor, not by The Hartford.
What phone number do I call to file an FMLA claim with The Hartford?
There isn't one universal number, it depends on your employer's specific Hartford contract. Check your benefits guide, HR portal, or paystub for the correct intake line. The portal most consistently referenced across employer plans is TheHartford.com/mybenefits.
How long does The Hartford take to approve an FMLA claim?
The Hartford doesn't publish a guaranteed processing time that applies to every plan. What is fixed by federal regulation is that your healthcare provider gets at least 15 calendar days to return a complete medical certification once it's requested, incomplete forms are the most common cause of delay.
Can The Hartford deny FMLA leave that I'm actually eligible for?
The Hartford can issue a wrong or disputable determination like any claims administrator, but it can't legally change what the FMLA statute entitles you to. If you believe a denial is incorrect, you can request the specific reason, submit additional documentation, use your plan's appeal process, or contact the DOL.
Does The Hartford handle both FMLA and short-term disability?
For many employers, yes. The Hartford is a major disability insurer as well as a leave administrator. But FMLA and STD are separate claims with separate rules. Confirm with your employer whether both run through The Hartford, and file both if so.
Does my manager or HR department decide my FMLA outcome if The Hartford is involved?
Generally no. When an employer outsources leave administration, the TPA (here, The Hartford) typically makes the FMLA designation call based on the medical certification and eligibility facts. Your manager can't override that determination, though HR can usually help you sort out documentation issues.
What information does The Hartford need to open a claim?
Typically your name, employer, employee ID or policy number, the reason for leave, your last day of active work, and your treating provider's contact information. Have these ready before you call or start an online claim.
Do I need to give The Hartford 30 days' notice before my leave starts?
If your leave is foreseeable (a planned surgery or an expected birth) federal FMLA regulations require you to give at least 30 days' notice when possible (29 C.F.R. § 825.302). If your need for leave isn't foreseeable, notify your employer and The Hartford as soon as you reasonably can instead.
What is The Hartford's "Leave Lens" or "Absence Dashboard"?
These are tools The Hartford introduced in 2024 as part of its absence-management platform, intended to help employers and employees track and plan leave. Whether you have access to them depends on what your specific employer purchased, not every Hartford-administered plan includes the same features.
If The Hartford denies my claim, how long do I have to appeal?
That deadline is set by your employer's specific plan, not by one Hartford-wide policy, check your denial letter for the exact window. Regardless of the plan's internal appeal deadline, you can also raise a federal FMLA violation with the DOL if you believe your statutory rights were ignored.
Does using The Hartford change how many weeks of FMLA leave I get?
No. FMLA guarantees up to 12 weeks of job-protected leave in a 12-month period (up to 26 weeks for military caregiver leave), regardless of which company administers the claim. The Hartford applies that entitlement to your case; it doesn't set a different number.
Can I be fired for taking FMLA leave that The Hartford approved?
No. Once leave is designated as FMLA, whether the determination came from The Hartford or your employer directly, federal law protects your job and prohibits retaliation for taking it. Being fired, demoted, or punished for taking approved FMLA leave is a violation you can report to the DOL.
