Severity definitions ensure the trauma benefit pays for genuinely serious medical events rather than minor or treatable conditions. They set a specific evidence threshold each event must meet, which keeps premiums affordable and aligns the payout with the financial shock the cover is designed to address.
Without severity definitions, a Trauma policy could be triggered by minor chest discomfort, an early-stage skin spot, or a brief neurological event with full recovery. Insurer pricing would have to assume frequent low-severity claims, pushing premiums substantially higher across the entire pool.
How severity definitions work
Each Critical Illness Event has a defined medical criterion that must be met before the benefit is payable. Typical thresholds include:
- Heart attack: evidence of myocardial necrosis (heart muscle damage) with cardiac biomarkers (troponin) elevated above a stated threshold, plus ECG changes or imaging evidence of new wall motion abnormality. Minor chest pain or a troponin leak below the clinical threshold does not meet the definition.
- Cancer: invasive cancer with histopathology confirming malignancy and staging. Most early-stage skin cancers and carcinoma in situ are excluded from the full benefit but may pay a partial benefit.
- Stroke: cerebrovascular event producing permanent neurological deficit lasting beyond a specified period, evidenced by imaging (CT or MRI). Transient ischaemic attack (TIA) without permanent neurological deficit is universally excluded.
- Coronary Artery Bypass Surgery: open-chest surgery to revascularise the heart muscle. Less invasive procedures such as angioplasty / stenting typically pay only as a partial benefit.
LICOP standardisation (first $2 million of cover)
The Life Insurance Code of Practice 2019 introduced industry-aligned definitions for cancer, heart attack, and stroke applicable to the first $2 million of cover. This was a response to historic inter-insurer variability that left consumers comparing apples and oranges on the headline conditions.
- Zurich Wealth Protection PDS (1 November 2025): Zurich automatically adopts the LICOP Trauma definitions for the first $2 million.
- OnePath OneCare PDS (1 October 2025): LICOP-derived definitions apply to the first $2 million.
- Other panel insurers follow comparable LICOP-aligned wording for the three main conditions within the same $2 million layer.
Beyond the LICOP layer (above $2 million of cover) and for non-LICOP conditions, insurer-specific definitions still apply.

What severity definitions exclude
Common exclusions due to severity threshold:
- Heart attack: "troponin leak" cases below the clinical threshold; chest pain without confirmed myocardial necrosis.
- Stroke: TIA without permanent neurological deficit (universal panel exclusion).
- Cancer: carcinoma in situ outside the listed partial-benefit sites; basal cell carcinoma and squamous cell carcinoma of the skin (other than invasive melanoma above the stated Breslow depth and Clark Level threshold).
- Coronary surgery: simple angioplasty without triple vessel disease (paid as partial in most policies, not full benefit).
How partial benefits soften the severity-threshold problem
The partial-benefit catalogue lets the insurer pay a smaller amount (10% to 25%) for conditions that don't meet the full severity threshold. This is materially different from a binary "yes or no" Trauma trigger. A client diagnosed with carcinoma in situ may receive a partial payout that funds initial treatment without exhausting their cover, leaving the bulk of the sum insured available for any future event.
Practical implications for application
- Compare the severity thresholds across panel insurers when shopping cover. The same diagnosis can produce different payouts.
- Check the partial-benefit catalogue. Strong partial coverage materially changes how often the cover pays.
- Read the survival period and qualifying period together. Severity thresholds apply at diagnosis, not at claim notification.
- Pay attention to LICOP layer ($2 million) versus above-LICOP layer if you carry a high sum insured.
Regulator anchor
The Life Insurance Code of Practice 2019 sets the LICOP-standardised definitions. The Life Insurance Act 1995 and Insurance Contracts Act 1984 govern the contract. APRA prudentially regulates insurer solvency; ASIC regulates conduct and disclosure. Severity definitions are insurer-set within the LICOP and PDS framework; they are not regulator-set.
