International critical illness insurance pays a tax-free lump sum on the diagnosis of a qualifying serious medical condition. The policy does not cover every medical condition — it covers a defined list of conditions that meet specified diagnostic criteria. For an expat or internationally mobile individual making a CI claim outside their home country, the difference between a well-defined, broad-coverage policy and a narrowly worded one can mean the difference between a paid claim and a disputed or declined one.
This guide covers the standard CI condition list in detail, explains how definitions vary between providers, addresses additional conditions offered by more comprehensive policies, and sets out why definition quality should be the primary evaluation criterion when comparing international CI products.
The Standard Core Conditions
The following conditions form the recognised core of a comprehensive critical illness policy. Most international CI products cover these; the differences lie in how they are defined.
Cancer
Cancer is statistically the most commonly claimed condition. The standard definition requires a malignant tumour characterised by the uncontrolled growth and spread of malignant cells, with invasion and destruction of tissue. Exclusions typically apply to carcinoma in situ (non-invasive), non-melanoma skin cancer, and low-grade prostate cancer. See the separate guide on critical illness cover and cancer for detailed coverage of cancer definitions.
Heart Attack
Myocardial infarction (heart attack) is defined by most CI policies as the death of heart muscle, confirmed by specific diagnostic criteria — typically a combination of characteristic clinical symptoms (chest pain), a rise and fall in cardiac biomarkers (troponin levels), and electrocardiographic evidence of new ischaemic changes. Policies that require all three elements simultaneously are more restrictive than those requiring any two of the three.
Stroke
Stroke is defined as a cerebrovascular incident causing permanent neurological deficit lasting a defined minimum period (typically 24 hours). Transient ischaemic attacks (TIAs), which resolve completely within 24 hours, are excluded by standard definitions. Some policies require the neurological deficit to persist at a defined minimum level — for example, causing a specified degree of functional impairment — rather than simply lasting 24 hours.
Kidney Failure
End-stage renal disease requiring permanent dialysis or kidney transplant. Temporary kidney failure that resolves without permanent dialysis does not qualify under standard definitions.
Organ Transplant
Receipt of a transplant of a major organ — heart, liver, lung, kidney, pancreas, bone marrow — or placement on an official transplant waiting list, depending on the policy wording. The waiting list provision is important: in practice, patients may wait extended periods for transplants and would be without financial support during that time without this extension.
Multiple Sclerosis
A diagnosis of MS with evidence of established clinical impairment. Some policies require the diagnosis to be made by a consultant neurologist and to show definite signs of the condition on neurological examination. Policies that additionally require a specific level of functional disability before paying may result in claims being declined during the early or relapsing-remitting phase of the disease.
Parkinson's Disease
Parkinson's disease is generally covered when diagnosed by a consultant neurologist and resulting in permanent clinical impairment. Some definitions require the condition to have caused a specified minimum level of functional disability. Early or mild presentations may not qualify under such definitions.
Alzheimer's Disease and Other Dementias
Alzheimer's and other forms of dementia are covered by most comprehensive CI policies, defined by a confirmed specialist diagnosis with evidence of permanent and irreversible impairment. Most definitions require impairment of two or more activities of daily living.
Paralysis
Permanent paralysis of two or more limbs (paraplegia) or complete loss of the use of limbs meeting a specified clinical threshold. Definitions vary in whether they require total versus partial paralysis and what degree of permanence is required.
Blindness and Deafness
Permanent and irreversible loss of sight in both eyes, or permanent loss of hearing in both ears, is standard. Loss in one eye or one ear alone is generally not sufficient. Some policies cover unilateral loss as an additional benefit or at a partial benefit level.
Loss of Limbs
Loss of two limbs by amputation or permanent and total loss of function, meeting specified clinical criteria.
Severe Burns
Burns covering a specified minimum proportion of the body surface area — typically 20% or more — or burns of defined severity affecting the face or limbs.
Coma
Loss of consciousness requiring continuous life support for a minimum defined period — commonly four or more days — with no prospect of recovery. Short-term medically induced coma does not qualify.
Coronary Artery Bypass Graft (CABG)
Open-heart surgery to bypass blocked coronary arteries, performed under general anaesthetic. Standard definitions cover CABG universally; older policy wordings may specify triple or quadruple vessel involvement.
Major Organ Failure
Heart valve replacement or repair, aorta graft surgery, and similar major cardiovascular surgical procedures are included in most comprehensive CI product lists.
HIV Contracted Through Medical Procedures
HIV acquired through a blood transfusion, organ transplant, or medical treatment in an accredited medical facility. Occupationally acquired HIV (for healthcare workers) is covered by some policies. Sexually acquired HIV is excluded.
Motor Neurone Disease and Other Neurodegenerative Conditions
MND, ALS, and related conditions are covered by most comprehensive CI products, with diagnosis by a consultant neurologist required.
Bacterial Meningitis
Bacterial meningitis resulting in permanent symptoms, confirmed by a specialist. The condition must have resulted in permanent neurological deficit; uncomplicated recovery from bacterial meningitis without lasting symptoms may not meet the definition.
Additional Conditions in Comprehensive International Policies
More comprehensive international CI policies may cover 40 to 50 or more conditions beyond the standard core list. Additional conditions that may be included in premium international products include:
- Benign brain tumour (non-malignant)
- Brain surgery
- Creutzfeldt-Jakob disease (CJD)
- Liver failure
- Lung disease requiring supplemental oxygen or transplantation
- Cardiomyopathy
- Pulmonary hypertension
- Aplastic anaemia
- Systemic lupus erythematosus (SLE) with major organ involvement
- Cerebral aneurysm requiring surgical treatment
- Peripheral vascular disease requiring arterial surgery
The value of additional conditions is not in the headline count but in whether the additional conditions are meaningful risks for the specific individual — and whether the definitions are genuine rather than narrowly drawn so as to rarely pay.
Definition Quality vs Condition Count
The most important principle in evaluating international CI cover is that definition quality matters more than condition count. A policy covering 50 conditions with restrictive definitions is inferior to a policy covering 30 conditions with comprehensive, claimant-friendly definitions.
When comparing CI products, key definition questions include:
- For cancer: are carcinoma in situ and non-melanoma skin cancers excluded? What prostate cancer criteria apply?
- For heart attack: are all three diagnostic criteria (symptoms, biomarkers, ECG) required simultaneously, or is any two sufficient?
- For stroke: is a 24-hour neurological deficit sufficient, or is a specific level of functional impairment required?
- For MS and Parkinson's: is the definition triggered by diagnosis alone, or does it require functional disability above a threshold?
- For benign brain tumour (if included): is the definition conditional on surgical removal, or does it also cover those managed conservatively?
This guide is for general information only. Critical illness insurance policy definitions, exclusions, and covered conditions vary between insurers and products and may change over time. Whether a specific diagnosis qualifies for a claim depends entirely on the terms of the individual policy. This is not medical or financial advice. Seek independent professional advice before arranging critical illness cover.

Frequently Asked Questions
How many conditions does a standard critical illness policy cover?
The standard ABI (Association of British Insurers) model for UK policies defines around 30 core conditions. International CI policies vary considerably — some match the domestic standard, while others cover 40, 50, or more. Condition count is a marketing metric; definition quality determines whether a claim will actually be paid.
Are all cancers covered by critical illness insurance?
No. Early-stage, pre-invasive, and non-invasive cancers are typically excluded. Carcinoma in situ, most non-melanoma skin cancers, and low-grade prostate cancers are commonly excluded. The policy must be read carefully to understand exactly which cancer presentations qualify.
Is Alzheimer's disease covered?
Most comprehensive CI policies do cover Alzheimer's disease and other forms of dementia, subject to a definition requiring a definitive diagnosis by a specialist physician, evidence of permanent impairment of two or more activities of daily living, and typically a requirement that the condition is of a specified minimum severity at time of claim.
Does critical illness insurance cover mental health conditions?
Standard CI policies do not cover mental health conditions such as depression or anxiety. Critical illness insurance is designed for clearly diagnosable physical conditions of defined medical severity. Some enhanced or specialised policies may include certain neurological conditions affecting cognitive function, but clinical mental health conditions are not part of the standard CI framework.
Is a heart bypass operation covered as a critical illness claim?
Coronary artery bypass graft (CABG) surgery is covered as a critical illness under most standard CI policies, subject to the specific definition — typically requiring the procedure to have been performed under general anaesthetic, with the specification of triple or quadruple vessel involvement in some older policy wordings. Modern policies generally cover all CABG procedures meeting the surgical definition.
