What an abdominal aortic aneurysm is
The aorta is the body's largest artery, carrying blood from the heart to the rest of the body. An abdominal aortic aneurysm — AAA — is a bulge in the section of the aorta that passes through the abdomen. An aneurysm is generally defined as a dilation of 3.0 cm or more, against a normal aorta of under 3 cm. Most aneurysms cause no symptoms and are found on imaging done for something else — which is why screening exists.
The danger is rupture: a ruptured abdominal aortic aneurysm is a surgical emergency, and published figures put its mortality as high as 80%. The risk of rupture rises with size, which is why guidelines generally recommend elective repair once the aneurysm reaches 5.5 cm, while smaller aneurysms are watched with periodic ultrasound. The U.S. Preventive Services Task Force recommends a one-time screening ultrasound for men aged 65 to 75 who have ever smoked (a Grade B recommendation, 2019), and Medicare covers a one-time screening ultrasound for people at risk when a doctor orders it.
How underwriters look at it
Underwriters evaluate an aneurysm on its type and location, its exact size, whether it is growing, how often it is being monitored, whether surgery has been recommended, and whether it has already been repaired. A smaller aneurysm that has stayed the same size on repeated imaging and is being properly monitored is a different underwriting case from one that is growing, causing symptoms, or awaiting recommended surgery — and one carrier may postpone an application that another is willing to consider.
Growth matters as much as size. Underwriting guides treat growth of more than 0.5 cm in 6 months, or 1 cm in a year, as a prompt for a vascular surgeon referral, and the change between imaging studies is one of the most useful pieces of information an applicant can supply. Smoking, blood pressure and cholesterol count too: an aneurysm rarely travels alone, and the rest of the cardiovascular picture is underwritten alongside it — the same logic as the site's guides to life insurance with high blood pressure and life insurance for diabetics.
What rate class to expect
No rate class is promised for any applicant here, but the range impaired-risk underwriting guides report is consistent. A dilation up to 3 cm is typically Standard risk. An aneurysm of 3 to 4.5 cm, stable for one year with good follow-up, is reported as a possible offer with a rating of around 100% above standard. An aneurysm larger than 4.5 cm that is not stable for a year, or not well followed, is reported as a possible decline. Conditions that themselves carry a poor outlook — Marfan syndrome, familial aortic aneurysm, vasculitis or Ehlers-Danlos type IV — are most often declined.
Repaired cases are reported separately: degenerative disease of the abdominal aorta treated by traditional open repair is reported as a possible offer with a rating of around 50% above standard, and endovascular repair with a stable ultrasound as a possible offer with a rating of around 75% after one year from surgery. These are reported ranges from impaired-risk broker underwriting guides, not carrier manuals, and the same applicant can get different answers from different carriers.
Life insurance after repair
There are two repairs. Open surgical repair replaces the weakened section of aorta through an abdominal incision. Endovascular aneurysm repair — EVAR — places a stent-graft inside the aorta through the arteries, without opening the abdomen. Both are viewed similarly by most underwriters, though EVAR usually has a shorter recovery period, and EVAR patients stay on a surveillance imaging schedule after the procedure.
Timing matters more than the method. Most carriers want to see at least six months of recovery before they will consider an application after repair, so they can confirm the repair was successful and healing is going well. An application made just before a planned repair, or just after one, is usually postponed rather than declined — a delay, not a verdict.
What to prepare
Have the record in the order an underwriter reads it: the latest imaging with the aneurysm's measurements and dates, the change between studies, the vascular surgeon's notes and whether repair has been recommended, the date and type of any repair, smoking status, blood pressure and cholesterol with their control status, and any other heart condition. A letter from the vascular specialist confirming a stable aneurysm with good follow-up can help an underwriter see past the diagnosis word to the record behind it.
Disclose the condition exactly as the application asks it: a material omission risks the claim itself under contestability. If the aneurysm was found on a screening ultrasound, say so, with the date and the measurement — a screening find with a small, stable measurement is the most favourable version of this file.
If the first answer is a rating, a postponement or a decline
A rating is not a rejection: it is a higher premium for the same benefit, and its size varies enormously by carrier for the same applicant. A postponement is a delay — recent diagnosis, repair just done, surgery pending — and the right move is usually to wait for the record to show stability, then reapply. A decline from one carrier is not a verdict on insurability.
If fully underwritten cover is not available, simplified-issue policies (health questions, no exam) and, as a last resort, guaranteed-issue policies (no health questions, higher price per dollar, usually capped benefits and graded early benefits) remain — but work down that ladder in order, fully underwritten first, simplified next, guaranteed last, because each step down costs more per dollar.
Worked example
Consider two ILLUSTRATIVE applicants. The first is 68, an ex-smoker who quit ten years ago, with a 3.4 cm abdominal aortic aneurysm unchanged on three annual ultrasounds, blood pressure controlled on medication and a normal echocardiogram. The second is 71, with a 5.2 cm aneurysm that grew 0.6 cm in six months, and whose vascular surgeon has recommended repair. An underwriter would view the first application very differently from the second — not because one diagnosis word is “better” in the abstract, but because size, growth, repair status and the rest of the heart all point in different directions. These are ILLUSTRATIVE contrasts to explain underwriting logic; they predict no real applicant's rate class, and no premium figure is asserted for either person.
Illustrative example only — not a fact about any real policy.
