The denial letter arrived in a thick envelope from Hartford, addressed to a 47-year-old project manager in Minneapolis who had been out of work on long-term disability for nine months with major depressive disorder and generalised anxiety. The envelope contained 31 pages: a benefit denial, a four-page summary of “subjective complaints lacking objective medical evidence,” and surveillance video stills from her front yard showing her carrying a bag of groceries from the car. The video was 17 seconds long. The denial reasoning leaned on it. She read the letter three times, called her treating psychiatrist, and then called an ERISA attorney whose name she had written down at a NAMI meeting six months earlier — back when she still believed her policy would simply do what it said it would do.
The mechanics of long term disability depression claims are uniquely punishing. The policies are technical, the federal law that governs most of them (ERISA) tilts toward the insurer, and the documentation that wins these cases looks nothing like what most treating psychiatrists routinely produce. This guide walks through how LTD insurers actually evaluate mental health claims, why most denials happen, the 24-month “mental nervous limitation” that quietly caps most policies, the appeal process, and what a properly built record looks like.
How long-term disability insurance treats mental health claims
LTD insurance comes in two flavours: group coverage purchased by an employer (governed by ERISA, the Employee Retirement Income Security Act of 1974) and individual disability income policies sold directly to professionals (governed by state insurance law). Roughly 80% of working Americans with LTD have it through an employer-sponsored group plan, which means ERISA governs the dispute, the appeal procedure, and any subsequent lawsuit.
Policy structure is consistent across major carriers — Unum, MetLife, Lincoln Financial, Hartford, Cigna, Reliance Standard, Prudential, Standard Insurance, Sun Life. After an elimination period (typically 90 or 180 days), benefits begin and pay 50% to 66.7% of pre-disability earnings, up to a monthly cap. For the first 24 months, “disabled” usually means unable to perform the material duties of your own occupation. After 24 months, the definition shifts to “any occupation” — any job for which you are reasonably qualified by education, training, or experience.
The 24-month mental nervous limitation: the cliff that ends most claims
Buried in the policy — usually pages 30 to 50 of a 90-page document — is the limitation that decides most depression and anxiety LTD claims. Most group policies cap benefits for “mental, nervous, or emotional disorders” at 24 months total. After that window, benefits terminate even if the claimant remains fully disabled, unless the disability is also caused by a non-mental-nervous condition (chronic pain, neurological disease, autoimmune disease, traumatic brain injury) that independently meets the policy definition.
The cliff is brutal because it lands precisely when the claimant has stopped working, exhausted savings, and structured life around the policy continuing to pay. Three points worth knowing before the cliff arrives:
- Some policies exempt specific conditions. Bipolar I disorder, schizophrenia, and dementia are exempt from the mental nervous limitation in many policies because they are classified as “biologically based” or “organic.” Read the exclusion language carefully — it matters at month 22.
- Co-occurring physical conditions can extend benefits. If the claimant also has fibromyalgia, lupus, multiple sclerosis, post-concussive syndrome, or another condition that independently meets the disability definition, benefits should not terminate at 24 months. The treating physicians need to document the physical condition as a separate, independent cause of disability.
- Individual disability policies often have no mental nervous limit. Higher-end individual policies sold to physicians, lawyers, and executives sometimes pay full benefits to age 65 or 67 for mental health disability. Premiums reflect that.
Why most depression and anxiety LTD claims get denied
Insurers do not use a single pretext for denying mental health claims. The pattern across denied claims is a cluster of rationales that reappear over and over:
- “Insufficient objective medical evidence.” Mental health is largely a subjective discipline — DSM diagnoses are made on history and observation, not biomarkers. Insurers exploit that by demanding objective findings that the field does not routinely produce. The countermeasure is structured: validated rating scales (PHQ-9, GAD-7, MADRS, BDI-II), neuropsychological testing, and functional capacity evaluations adapted to cognitive demands.
- “Subjective complaints not corroborated by examination findings.” Translation: the chart says the patient reported feeling unable to concentrate, but the mental status exam was unremarkable. Treating clinicians often write succinct mental status exams that, when read by a hostile reviewer, look like evidence of normal functioning.
- Surveillance evidence. The carrier hires an investigator to film the claimant carrying groceries, attending a child’s soccer game, picking up a prescription. Activities of daily living are then framed as inconsistent with disability. The reality — that someone with severe depression can shower, drive to a pharmacy, and still be unable to sustain 8 hours of cognitive work product per day — does not always survive the framing.
- Independent medical examinations (IMEs). The carrier sends the claimant to a psychiatrist or psychologist of its choice, who produces a report often concluding that the claimant has full work capacity. IME reports are routinely the centerpiece of the denial.
- Treating physician statements that are too brief. A “patient is disabled, cannot work” letter is not enough. The carrier expects functional documentation tied to job demands — concentration, persistence, pace, social interaction, adaptation.
Building the medical record that wins the appeal
The single most important contribution from the treating clinician is a detailed work-capacity opinion that translates clinical symptoms into job-relevant functional limitations. The American Medical Association’s Guides to the Evaluation of Permanent Impairment provide one framework; Social Security’s Mental Residual Functional Capacity (MRFC) framework provides another. Either way, the document needs to address concentration, pace, persistence, ability to interact with the public and coworkers, ability to adapt to changes in routine, and capacity to maintain an ordinary work schedule.
Cognitive testing matters more than most claimants realise. A neuropsychological battery — typically 4 to 8 hours administered by a clinical neuropsychologist — produces objective data on attention, processing speed, working memory, and executive function. Performance validity tests embedded in the battery defend against malingering accusations and convert a “subjective” claim into a documented finding the carrier struggles to dismiss.
A vocational assessment by a certified rehabilitation counselor adds a second layer. The vocational expert evaluates the pre-disability occupation against documented functional limitations and offers an opinion on whether sustained performance is possible. In an “any occupation” review at month 24, that vocational analysis becomes essential.
Surveillance and social media: what claimants need to know
Carriers routinely contract with private investigators to conduct video surveillance, especially around the 90-day, 180-day, and 24-month policy milestones. Surveillance is legal in public spaces in every U.S. state. Investigators may sit outside the home for 8 to 12 hours and produce edited highlight reels showing the claimant doing anything that looks active.
Social media is reviewed in parallel. Photographs of vacations, gym workouts, social events — all of it ends up in claim files. Privacy settings are not a defense. Disability attorneys uniformly counsel clients to either stop posting publicly during a claim or accept that everything posted will be screenshotted and presented out of context.
The ERISA appeal process — and why you cannot skip it
If your LTD policy is governed by ERISA — virtually all employer-sponsored plans except those of churches and government employers — the federal statute mandates a specific appeal procedure. After a denial, you have 180 days to file an administrative appeal in writing. The carrier then has 45 days (with one 45-day extension) to decide. Some plans require a second-level mandatory appeal before litigation; many do not.
The most consequential ERISA rule is this: in any subsequent federal court lawsuit, the judge generally cannot consider evidence outside the administrative record built during the appeal. The doctors’ letters, neuropsych report, vocational analysis, surveillance rebuttal, and rebuttal expert opinions all need to be filed during the 180-day window. Evidence developed later — even if devastating to the carrier’s position — will usually be excluded. That single rule is why ERISA disability lawyers earn their fees: they treat the administrative appeal as the trial, because in practical terms it is.
Standard of review at trial also tilts the playing field. If the plan grants the carrier discretionary authority to interpret the policy and decide claims (most do), federal courts apply “abuse of discretion” review — the court asks only whether the carrier’s decision was reasonable, not whether it was correct. Some states (California, Illinois, New York, Texas, Connecticut, others) ban discretionary clauses by statute or insurance regulation, which restores de novo review. Whether your state has such a ban significantly affects the value of your claim.
When and how to hire an ERISA disability attorney
The honest answer: as soon as you receive a denial, and ideally before. The 180-day appeal window is the only chance to build the administrative record. Attorneys who specialise in ERISA disability work on contingency — typically 25% to 40% of recovered benefits, including past-due lump sum and a percentage of future monthly benefits for a defined period.
Vetting questions to ask in an initial consultation:
- How many ERISA mental health LTD appeals has the firm handled in the last three years?
- What is the firm’s appeal-stage reversal rate, and what is the federal court litigation track record?
- Will the firm front the cost of a neuropsychological evaluation and vocational assessment if needed?
- Who in the firm will actually write the appeal — partner, associate, or paralegal?
- How does the firm handle ongoing administrative reviews after a successful claim?

Alternatives and parallel claims: SSDI, SSI, and state disability
Most LTD policies require claimants to file for Social Security Disability Insurance (SSDI) and offset LTD benefits by the SSDI amount once approved. SSDI uses a different standard — inability to perform any substantial gainful activity for at least 12 months — but the documentation that supports an LTD claim usually supports SSDI as well. The first SSDI denial rate runs near 65% nationally; reconsideration and ALJ hearings reverse a meaningful share. The Social Security Administration’s eligibility rules and listing-level criteria are at ssa.gov.
Five states — California, Hawaii, New Jersey, New York, and Rhode Island — plus DC and Puerto Rico maintain state disability programs (SDI or TDI) that pay short-term partial wage replacement, often covering the gap before the LTD elimination period ends. Our broader piece on mental health disability through SSDI and SSI covers federal programs, and our guide on mental health coverage after job loss covers the COBRA and ACA marketplace options that often run in parallel.
Frequently asked questions about long-term disability for depression
Can I get LTD benefits for depression and anxiety alone?
Yes — but most group policies cap mental health benefits at 24 months. To win benefits in the first place, you need detailed clinical documentation, validated symptom scales, and a treating physician’s work-capacity opinion that translates symptoms into functional limitations. Approval is harder than for physical disability, but it is far from impossible.
What is the 24-month mental nervous limitation?
It is a clause in most group LTD policies that caps benefits for mental, nervous, or emotional disorders at 24 months total. After that, benefits terminate unless the claimant has a co-occurring physical condition that independently meets the disability definition, or the policy specifically exempts the diagnosis (often the case for bipolar I, schizophrenia, and dementia).
How long do I have to appeal an LTD denial?
Under ERISA, 180 days from receipt of the written denial. Individual policies vary by state and contract. Do not let the deadline pass — the administrative appeal is your main and possibly only chance to build the record that a federal court will see if the case proceeds to litigation.
Will surveillance footage automatically end my claim?
No. Surveillance must be put in clinical context. A short clip of grocery shopping does not negate documented inability to sustain cognitive work for 8 hours a day. A good appeal directly engages the surveillance, has the treating clinician explain why the activities shown are consistent with the documented diagnosis, and rebuts the carrier’s framing.
Should I file for SSDI while my LTD claim is pending?
Almost always yes — most policies require it, and SSDI approval can support the LTD claim. Be aware that LTD benefits will be reduced by the SSDI amount once SSDI is awarded, and back pay from SSDI may need to be repaid to the LTD carrier under offset provisions.
The bottom line
Winning a long term disability depression claim is not a paperwork exercise — it is a litigation-prep exercise that begins the moment a claimant decides they cannot work. The 180-day ERISA window, the 24-month mental nervous limitation, the surveillance reality, and the documentation gap between routine psychiatric chart notes and what an insurance reviewer demands are the four hinges that decide outcomes. Build the record while the door is open. Hire counsel before the first appeal. And do not assume the policy will do what the brochure suggested.
