Understanding the difference for employers
When reviewing employee benefits, many employers focus on health-related protection but are often uncertain about the differences between group critical illness cover and group health insurance. Although both benefits support employees during periods of ill health, they are designed to address very different risks and outcomes.
Group critical illness cover vs group health insurance
| Area | Group critical illness cover | Group health insurance (PMI) |
|---|---|---|
| Primary purpose | Provides financial support following a serious diagnosis | Provides access to eligible medical treatment |
| Claim trigger | Diagnosis of a covered condition meeting the policy definition | Eligible treatment or investigation under the policy |
| Benefit type | Cash lump sum | Payment of eligible treatment costs |
| Who benefits? | Usually the employee | Treatment provider via insurer funding |
| Use of benefit | Employee decides how to use funds | Restricted to policy-covered treatment |
| Private treatment costs | Not directly | Yes, subject to policy terms |
| Can support lost income or bills | Potentially yes | Generally no |
| Problem solved | Financial impact of serious illness | Access to diagnosis and treatment |
What is group critical illness cover?
Group critical illness cover is a protection policy that may pay a lump sum benefit directly to an insured employee if they are diagnosed with a condition that meets the insurer’s policy definition and satisfy any relevant policy conditions, exclusions and survival requirements.
The policy specifies which conditions are covered and, importantly, how those conditions are defined. Definitions, qualifying periods and exclusions can vary between insurers.
What is group health insurance?
Group health insurance, often referred to as private medical insurance, is designed to fund eligible healthcare costs and provide access to healthcare services in accordance with policy terms, conditions, exclusions and benefit limits rather than paying a cash lump sum following diagnosis.
Can an employee claim under both benefits?
Potentially, yes. The two benefits address different needs and are often designed to work alongside one another. A successful claim under one policy does not automatically create entitlement under the other. Each claim is assessed against its own policy terms.

Key considerations for HR directors
- Workforce demographics
- Budget and affordability
- Existing benefits provision
- Employee demand and engagement
- Recruitment and retention objectives
- Policy definitions, exclusions and insurer support services

Building a balanced protection strategy
Group critical illness cover helps provide financial support following the diagnosis of a covered serious illness. Group health insurance helps employees access eligible medical treatment and specialist care. For many employers, the most effective approach is not choosing between the two benefits, but understanding how they can work together within a broader health, wellbeing and financial protection strategy.
