How long do I have to appeal a denied LTD claim under ERISA?

Under ERISA regulations (29 C.F.R. §2560.503-1), you generally have at least 180 days from the denial notice to file your administrative appeal. This deadline is strict — missing it typically forfeits your right to sue in federal court. Read your denial letter carefully; the specific deadline is stated there. Some plans allow longer windows, but assume 180 days as the floor and act quickly. If you need more time to gather medical evidence, request an extension in writing before the deadline — not after.

Can I add new medical evidence after my administrative appeal is denied?

Usually no. This is the critical rule most claimants learn too late. Under ERISA's closed-record doctrine, federal courts reviewing a denied LTD case are limited to the administrative record that existed when the plan made its final decision. New imaging results, new doctors' opinions, or new diagnoses discovered after the appeal closes cannot be introduced in federal litigation. This is why building a complete, carefully structured medical record before submitting your appeal is the most important action you can take.

What is the difference between own-occupation and any-occupation disability definitions — and why does it matter at month 24?

Own-occupation means you are disabled if you cannot perform the material duties of your specific job. Any-occupation means you are disabled only if you cannot perform any job for which you are reasonably qualified by education, training, or experience. Most group LTD policies switch from own-occupation to any-occupation after 24 months — a definition change that dramatically raises the evidentiary bar for continued benefits. If your 24-month transition is approaching, you need a functional capacity evaluation, updated physician opinions specifically addressing the any-occupation standard, and potentially an independent vocational expert report — before the transition date, not after.

Long-Term Disability Claim Denied? Your 2026 ERISA Appeal...

The denial letter arrives, and most people’s first instinct is to call their insurance company and argue. That instinct is understandable and almost always counterproductive.

Your insurance company’s decision is not made in a phone call. It is made in the administrative record: the file of medical documents, surveillance notes, internal reviews, and vocational assessments that the insurer has been building since before it denied you. To change the decision, you need to build a better record. Under ERISA, the federal law governing virtually all employer-sponsored group LTD plans, that record closes at the end of the administrative appeal process, permanently.

This means your appeal is not a preliminary step before the real fight. Your appeal is the real fight.

Why ERISA matters more than you realize

If your long-term disability coverage came through your employer, it is almost certainly governed by the Employee Retirement Income Security Act of 1974 (ERISA), specifically ERISA §503 and its implementing regulations at 29 C.F.R. §2560.503-1.

ERISA creates a mandatory dispute process:

You receive a denial with stated reasons and your appeal rights
You file an administrative appeal within the deadline stated in your denial letter (ERISA regulations require at least 180 days)
The insurer reviews the appeal and issues a final decision
Only after exhausting this process can you file suit in federal court under ERISA §502(a)(1)(B)

The closed-record rule: once the administrative record closes, federal courts review only what was in the file. No new evidence, no new doctors, no trial witnesses. This is fundamentally different from state-court insurance litigation, where you can develop evidence throughout the case. ERISA’s closed-record rule means that every medical document, every treating physician opinion, every functional limitation description, and every rebuttal of the insurer’s reviewers must be in the file before you submit the appeal.

Most group LTD plans also include a discretionary authority clause, language giving the insurer discretion to interpret plan terms and determine eligibility. If your plan has this clause, courts apply an “arbitrary and capricious” standard rather than de novo review. This deferential standard makes winning in court harder. A strong administrative record is your best defense: courts are less likely to defer to an insurer whose claim review was procedurally deficient or whose reasoning was contradicted by the weight of the medical evidence.

The own-occupation to any-occupation transition: the 24-month cliff

The single most common trigger for LTD terminations is the definition-of-disability change at month 24.

Period	Definition	What it means in practice
Months 1–24	Own-occupation	Can you do your specific job?
Month 25+	Any-occupation	Can you do any job suited to your education and experience?

For a white-collar professional with a serious but not catastrophic impairment, the transition from own-occupation to any-occupation is where benefits are terminated, even when the claimant’s condition has not improved. The insurer now only needs to identify sedentary jobs that exist in significant numbers in the national economy.

If your 24-month anniversary is approaching:

Commission a formal Functional Capacity Evaluation (FCE) from a licensed physical or occupational therapist (this creates an objective, standardized record of exactly what activities you can and cannot sustain)
Obtain updated physician opinions that specifically address the any-occupation standard
Retain an independent vocational expert who can evaluate the specific jobs the insurer is likely to cite

Many plans also impose a 24-month limitation on mental health benefits, caps on benefits for depression, anxiety, PTSD, and related conditions. These caps are legal under ERISA in most states. Check your policy’s mental-nervous limitation clause now, not at month 23.

How insurers build their denial cases

Understanding insurer tactics makes them easier to counter.

Surveillance. Insurers routinely hire private investigators to film claimants. Video of you carrying groceries or walking to a car is edited to imply full function. The solution is not to become housebound. The solution is ensuring your medical record thoroughly documents what you can do on good days versus bad days, what the cost of activity is (post-exertional malaise, pain spikes), and why isolated observed activity does not translate to sustained work capacity.

Independent Medical Examinations (IMEs). The insurer selects and pays a physician to examine you. These examiners often have established financial relationships with insurers, seeing large volumes of insurer-referred cases each year. IME reports contradicting your treating physicians are common. Counter them with updated treating physician opinions that specifically address the IME’s conclusions.

Paper-only peer review. Some denials are based on a physician hired by the insurer reviewing your file without ever examining you. Courts have viewed paper-only reviews skeptically when the reviewing physician’s opinion conflicts with treating physicians who actually examined the claimant. Document and preserve this distinction explicitly in your appeal.

Vocational reviews. For any-occupation denials, an insurer-retained vocational expert identifies jobs the insurer claims you can perform. These opinions are countered by your own vocational expert report analyzing whether the cited jobs actually exist in significant numbers, match your education and work history, and are feasible given your documented functional limitations.

What to do within 30 days of the denial

Read the denial letter in full. Note the specific stated reasons, the exact appeal deadline, and the address for the appeal submission. The deadline typically runs from the date on the letter, not the date you received it.
Request your complete claim file. Under ERISA, you are entitled to all documents, records, and information relevant to your claim. Send a written request immediately. Insurers have 30 days to respond. Review the file for missing records, surveillance reports, and the IME physician’s financial relationship with the insurer.
Do not discuss your case informally with the insurer. Every recorded call can become part of your administrative record. Communicate in writing from this point forward.
Update your treating physicians. Ask for opinions that document functional limitations in specific, measurable terms, not just diagnoses. “Patient cannot maintain seated concentration for more than 20 minutes” is useful evidence. “Patient has chronic pain” is not.
Consult an ERISA LTD attorney immediately. Because of the closed-record rule, attorney involvement before the appeal is submitted (not after) dramatically improves outcomes. Most experienced ERISA LTD attorneys offer free consultations and work on contingency, collecting a percentage of back benefits recovered only if you win.
Keep a daily symptom journal. Document good days, bad days, activity limitations, medication side effects, and how long you can sit, stand, or concentrate. This contemporaneous record corroborates your physicians’ opinions and contextualizes any surveillance footage.

Building a strong administrative appeal

A strong appeal is a comprehensive, proactive submission, not a letter expressing disagreement.

Medical evidence package: updated treating physician notes, all specialist evaluations, imaging studies with radiologist reports, pharmacy records, and (for most cases) a formal FCE. The FCE provides standardized, objectively measured documentation of your physical and cognitive work capacity.

Vocational evidence: if the denial cites jobs you could theoretically perform, obtain an independent vocational expert (VE) report. A VE can analyze whether those jobs exist in significant numbers, whether they match your background, and whether your FCE rules them out.

Rebuttal of IME and peer review: obtain written responses from your treating physicians that specifically address, point by point, the conclusions of any insurer-retained reviewer. Courts have found it significant when treating physicians who examined the claimant disagree with paper reviewers who did not.

Consistent narrative: social media posts, recorded phone calls, and offhand statements can undermine a well-documented claim. Present a consistent, documented picture across all channels.

Attorney fees and when to get help

ERISA LTD attorneys almost universally work on contingency: no upfront fee, with the attorney collecting a percentage of back benefits recovered only if you win. Commonly cited contingency rates range from 25–40% of past-due benefits recovered.

Under ERISA §502(g), courts may also award attorney fees against the insurer, providing an additional incentive for qualified attorneys to take strong cases.

The most important thing to know: consult an attorney before you submit your administrative appeal, not after it is denied. Once you submit your appeal and the insurer issues its final decision, the record closes. An attorney who enters after that point has far less to work with.

After administrative appeals are exhausted

If your final administrative appeal is denied, you can sue in federal district court under ERISA §502(a)(1)(B). Key features of ERISA federal litigation:

Court applies “arbitrary and capricious” review if the plan grants the insurer discretionary authority (most do), a deferential standard that makes winning harder but not impossible
Court reviews only the administrative record: no trial, no new witnesses, no new evidence
Cases are decided on written briefs
Resolution typically takes one to three years; settlement is common at multiple stages

The closed-record rule makes the quality of the administrative appeal the single most important determinant of federal litigation success. A well-built record (thorough, consistent, medically detailed, proactively rebutting every denial reason) is what turns an “arbitrary and capricious” standard into a manageable hurdle.

The 180-day appeal deadline is real. The closed-record rule is real. Act on the day the denial letter arrives — not in week eight.
