In insurance law, a physical infirmity is a chronic, settled physical condition that has become part of how your body ordinarily functions. The term matters most in accidental death and dismemberment (AD&D) policies and some life insurance riders, where insurers can deny claims for losses “caused or contributed to” by a pre-existing infirmity. Whether a denial sticks usually turns on how much the condition actually contributed to what happened, and courts generally require it to have been a substantial factor rather than a bystander in your medical history.
What Counts as a Physical Infirmity
Not every health problem qualifies. A physical infirmity is a condition that has settled in, meaning it is woven into your body’s daily operation rather than something that flares up and resolves. A broken arm that heals in six weeks is a temporary injury. Chronic heart disease that permanently alters how your cardiovascular system works is an infirmity. Courts have described the threshold as a condition significant enough that it “would be characterized as a disease or infirmity in the common speech of men,” which is a roundabout way of saying the average person would recognize it as a real, lasting health problem.
Conditions that typically meet the standard include advanced cardiovascular disease, permanent loss of limb function, structural bone abnormalities, significant hearing or vision loss, and chronic respiratory conditions requiring ongoing management. What they share is a lasting departure from healthy physical functioning that will not resolve through the body’s natural healing. A mere predisposition to disease, or a dormant condition that has never produced symptoms, usually falls short.
The line between a pre-existing condition and an infirmity matters in practice. A slightly elevated cholesterol reading on your chart is a pre-existing condition, but probably not an infirmity. If that same situation has progressed to coronary artery disease requiring medication and limiting your physical activity, you have crossed into infirmity territory. The shift happens when the condition moves from a data point in your file to something that meaningfully shapes how your body works.
How Infirmity Clauses Work in AD&D and Life Policies
AD&D policies are where you will most often run into infirmity language. These policies typically define a covered “injury” as an accidental bodily injury that is the direct result of an accident, independent of any disease or infirmity. On top of that definition, the exclusion section separately bars coverage for any loss “caused or contributed to by disease or infirmity of mind or body.”1Interstate Insurance Product Regulation Commission. Additional Standards for Accidental Death and Dismemberment Benefits That two-layer structure gives insurers two separate hooks to deny a claim whenever a chronic condition is anywhere in the picture.
A common scenario: someone with a known heart condition falls and suffers a fatal head injury. If the fall was triggered by a cardiac episode, the insurer argues the infirmity caused the fall and denies the benefit. If the person tripped on a loose stair, the accident was the cause and the heart condition was incidental. Real cases rarely sort themselves that cleanly. Most disputes land in a gray zone where the insurer can point to medical records showing a chronic condition and argue it played some role. Insurers also have the right to request physical examinations, and in death claims, autopsies, to look for internal factors that may have contributed to the loss.1Interstate Insurance Product Regulation Commission.

The Causation Standard an Insurer Actually Has to Meet
“Caused or contributed to” sounds broad, and insurers read it that way. Courts have consistently narrowed it. The prevailing rule is that an infirmity must be a substantial contributing factor to the loss before an insurer can rely on the exclusion. A condition that existed but played no meaningful role in the accident does not satisfy it. This is where most disputed claims are fought and won.
The distinction between dormant and active conditions drives many outcomes. A latent condition sitting quietly in the background is generally treated as too remote to count as a proximate cause. If the accident would have produced the same injury whether or not the infirmity existed, the exclusion does not apply. An active, life-threatening condition that directly triggered the chain of events leading to injury or death will support a denial. The question is whether the infirmity had a meaningful causal connection to the specific loss, not whether it appeared somewhere in the person’s medical history.
For claimants, the practical lesson is straightforward. A minor circulatory issue that never affected your daily life probably will not let an insurer escape paying on an AD&D claim after an accidental fall. A severe cardiac condition that caused the fall likely will. The insurer carries the burden of showing the infirmity contributed substantially, which takes more than pulling the diagnosis out of your records.
Health Insurance Works Differently
If you are worried about a physical infirmity affecting your health coverage, the rules are not the same. Under the Affordable Care Act, health insurers cannot refuse coverage, charge higher premiums, or limit benefits because of any pre-existing condition, including chronic physical infirmities.2U.S. Department of Health and Human Services. Pre-Existing Conditions Federal law specifically prohibits group and individual health plans from imposing any pre-existing condition exclusion.3Office of the Law Revision Counsel. 42 USC 300gg-3 Prohibition of Preexisting Condition Exclusions
One exception remains: grandfathered health plans that existed when the ACA took effect and have not made certain changes since may still impose pre-existing condition exclusions.2U.S. Department of Health and Human Services. Pre-Existing Conditions Those plans are increasingly rare but not extinct. AD&D policies, life insurance, and disability insurance are not covered by the ACA’s protections, which is why infirmity clauses stay alive in those products.
Waiver of Premium When an Infirmity Progresses
Life insurance policies often include an optional rider that waives your premium payments if you become totally disabled. If a physical infirmity progresses to the point where you can no longer work, this rider can keep your policy in force at no out-of-pocket cost. The usual structure requires total disability to continue for a consecutive waiting period, commonly six months, before the waiver begins. Shorter waiting periods of up to 90 days may apply for qualifying conditions that do not rise to total disability.4Interstate Insurance Product Regulation Commission. Additional Standards for Waiver of Premium Benefits for Total Disability and Other Qualifying Events
Once the insurer approves the waiver, it can require proof of continued disability no more than once every 30 days for the first two years. After that period, the company can only ask for proof once per year.4Interstate Insurance Product Regulation Commission. Additional Standards for Waiver of Premium Benefits for Total Disability and Other Qualifying Events Any physical examination the insurer requires must be at the insurer’s expense, and if a second or third medical opinion is needed to resolve a dispute, those costs also fall on the insurer. If you need to file a waiver claim, the insurer must provide the claim forms within 10 working days of your request. If it fails to do so, submitting a written description of your condition and its effect on your ability to work counts as meeting the requirements.
If an Insurer Denies Your Claim
If your employer sponsors the plan, it almost certainly falls under the Employee Retirement Income Security Act, which governs how claims must be processed and appealed. ERISA sets specific timelines. For an initial disability claim determination, the plan has 45 days from receipt of the claim, with two possible 30-day extensions if it provides written notice explaining the delay.5eCFR. 29 CFR 2560.503-1 Claims Procedure For group health plan claims, the initial determination window is shorter: 30 days for post-service claims and 15 days for pre-service claims.
When a claim is denied, the denial notice must explain the specific reasons, identify the plan provisions relied upon, and describe what additional information you would need to provide to perfect the claim. You then have at least 180 days to file an internal appeal.5eCFR. 29 CFR 2560.503-1 Claims Procedure On that appeal, the reviewer cannot be the same person, or a subordinate of the person, who made the initial denial. If the denial rested on a medical judgment, the plan must consult with a qualified health care professional who was not involved in the original decision.
If the internal appeal fails, you have the right to file a lawsuit to recover benefits under federal law.6Office of the Law Revision Counsel. 29 USC 1132 Civil Enforcement The standard of review in court depends on your plan’s language. If the plan does not grant the administrator discretion to interpret it, the court reviews the denial fresh, with no deference to the insurer’s decision.7Justia US Supreme Court. Firestone Tire and Rubber Co v Bruch, 489 US 101 (1989) If the plan does grant discretionary authority, the court gives more deference but still weighs any conflict of interest, particularly when the same company that pays the claims also decides whether to approve them. Exhausting the internal appeal before filing suit is not optional; courts will generally dismiss a case if you skipped the administrative steps.
