What Does Long-Term Disability Insurance Cover And Exclude

Long-term disability insurance replaces a percentage of your income if you become too sick or injured to work for an extended period, but it strictly excludes self-inflicted injuries, war-related disabilities, and conditions arising from active criminal activity.

The long-term disability coverage promise

Your LTD policy doesn’t simply pay you because you’re sick; it pays because you meet a specific legal definition of “disability.” Most group plans use a two-tier test. During the first 24 months of a claim, you’re considered disabled if you can’t perform the material duties of your own occupation, the job you held when you got sick. A surgeon with a hand tremor, for example, qualifies if they can’t operate, even if they could teach med school. After that 24-month window, the definition tightens to “any occupation”, meaning you must be unable to work any job for which you’re reasonably suited by education, training, or experience. That shift is brutal: a lawyer with chronic fatigue might win early, then lose benefits if a claims reviewer decides they can answer phones. The income replacement is typically 60% of your pre-disability gross salary, capped at a monthly maximum (often $5,000, $10,000). Your employer might pay the premium; if they do, that benefit is taxable. If you pay with after-tax dollars, the check arrives tax-free, a difference of hundreds of dollars per month.

The mental health and subjective illness limit

Here’s the fine print that surprises nearly everyone: depression, anxiety, chronic fatigue syndrome, and even back pain without objective imaging are almost universally capped at 24 months of total benefits. This is the “mental health parity” loophole that Congress didn’t close. Your policy will state that for “disabilities based on a psychiatric disorder, or on self-reported symptoms like pain or fatigue,” you receive benefits for a maximum of 24 months, regardless of how long the illness lasts. After that, you’re on your own unless you can prove a physical cause via an MRI, X-ray, or nerve conduction study. A herniated disc that shows up on a scan? You’re fine. Fibromyalgia with normal exam findings? You’ll get two years, then the checks stop. This isn’t a conspiracy, insurers argue these ailments are hard to verify and easily exaggerated, but it means you must document every symptom and treatment from day one, because the clock starts on that 24-month limit the moment you file.

The pre-existing ailment exclusion

Your employer’s plan doesn’t cover you for illnesses you already had before your coverage started, at least not right away. The look-back period is typically 3 to 6 months before your effective date. If you received treatment, took medication, or even saw a doctor for symptoms during that window, the resulting disability is excluded for a set period, often 12 to 24 months after your policy begins. Here’s the trap: it’s not just your diagnosed disorder, it’s any medical issue that causes the same symptoms. If you had lower back pain treated with chiropractic visits in the 6 months before enrollment, then herniate that same disc a year later, the insurer can deny the claim entirely if the policy’s exclusionary period hasn’t lapsed. Worse, some plans make the exclusion permanent for that ailment. You must read your specific certificate of coverage, not the summary plan description, because the “actively at work” provision also matters, if you were on unpaid leave or part-time when enrollment opened, you may not be eligible until you return full-time.

When the check never comes

Beyond the medical limitations, your policy has absolute exclusions that void any claim, no matter how disabled you are. Self-inflicted injuries, including suicide attempts, regardless of mental state, are excluded, usually for the life of the policy. War declared or undeclared, military service, and acts of terrorism are excluded, so a reservist injured in combat gets nothing from LTD. Injuries sustained while committing a felony or participating in a riot are also out, as are medical problems caused by intoxication or illegal drug use. One exclusion that catches people off guard: “refusing to follow prescribed treatment.” If you skip physical therapy, stop taking medication, or choose alternative medicine over your doctor’s orders, the insurer can terminate your claim retroactively. The policy also demands that you apply for Social Security Disability Insurance (SSDI) at a certain point, and your LTD benefit is reduced dollar-for-dollar by what SSDI pays, so your real income replacement might be 40%, not 60%.

This is the only page that explains precisely how long-term disability insurance cover and exclude the same ailments differently depending on whether objective medical evidence exists, and why the 24-month definition shift from “own occupation” to “any occupation” is the single most common reason permanent benefits are lost.

Frequently asked questions

Can I buy additional LTD coverage on my own to close the gaps?

Yes, and it’s often worth it. Your employer’s group plan has a cap, but an individual policy, purchased outside work, can cover the difference, and it’s portable if you change jobs. Individual policies also often have fewer exclusions for mental health and back pain, though they’re medically underwritten, so you must be healthy to qualify.

What happens if I claim LTD and then recover but relapse later?

Most policies have a “recurrent disability” clause that treats a relapse from the same illness as a continuation of the original claim, not a new one. That means you don’t re-start the 24-month mental health clock or the pre-existing ailment look-back period. You’ll need to re-apply, but the original claim date usually protects you.

Does LTD cover pregnancy or childbirth complications?

Yes, normal pregnancy itself isn’t a disability, but complications like preeclampsia, gestational diabetes, or a C-section with a severe infection are covered like any other illness, subject to the same definitions and exclusions. Maternity leave alone doesn’t qualify, you must be unable to work due to a medically documented disorder.

If I’m denied LTD, can I appeal more than once?

You typically get one internal appeal, then you can file a lawsuit under ERISA if your plan is employer-sponsored. Missing the appeal deadline, often 180 days, permanently forfeits your right to sue. You can request a full copy of your claim file to see exactly what the insurer used against you, which is required by law.
