Introduction: Health Insurance in South Africa — Why It Matters

In South Africa, health insurance is called ‘medical aid’ and is regulated by the Medical Schemes Act under the Council for Medical Schemes (CMS). Unlike most countries, South Africa’s medical schemes are governed by community rating — schemes cannot charge different premiums based on age or health status for the same plan, and must cover Prescribed Minimum Benefits (PMBs) regardless of which scheme you choose.

South Africa currently has 71 registered medical schemes serving approximately 9.13 million principal members and their dependants — in total, about 9.5 million beneficiaries or 16% of the total population. The remaining 84% of South Africans rely on the public healthcare system. This guide covers South Africa’s top medical aid schemes, their premiums, what they cover for specific diseases, and which plan is best for your health needs in 2025.

💊 What Are Prescribed Minimum Benefits (PMBs)?

Prescribed Minimum Benefits are a set of 270 medical conditions and 25 chronic diseases that ALL registered South African medical schemes must cover in full, regardless of which plan you are on. This is a legal requirement under the Medical Schemes Act, protecting all members from catastrophic medical expenses for defined conditions. PMBs include conditions like heart attacks, strokes, cancer, diabetes, epilepsy, HIV/AIDS, asthma, TB, and major trauma requiring emergency surgery.

All 71 registered medical schemes MUST cover PMBs — it is the law
PMBs cover: 270 defined conditions + 25 chronic diseases
Key PMB diseases: HIV/AIDS, TB, cancer, heart attack, stroke, diabetes, epilepsy, kidney failure, asthma, mental illness
PMBs must be paid in full with no co-payments at designated service providers (DSPs)
Verify PMB status with your scheme before any hospital admission
