How many medical schemes are there in South Africa?
There are 71 medical schemes registered with the Council for Medical Schemes (CMS), the statutory regulator that oversees the industry under the Medical Schemes Act 131 of 1998. Between them, these schemes cover more than 9.1 million beneficiaries. The figures come from the CMS Annual Report 2024/25.
That number sounds like a lot of choice, but it is smaller than it looks. Only 16 of the 71 schemes are open to the general public. The remaining 55 are restricted schemes, which means you can only join them if you work for a particular employer or belong to a particular industry or profession.
Open versus restricted schemes: what is the difference?
An open scheme must accept any applicant who applies and agrees to the scheme rules. It does not matter who you work for. Discovery Health, Bonitas and Momentum are all examples of open schemes.
A restricted scheme limits membership to a defined group. Government employees, mineworkers, bank staff and university employees often have their own restricted schemes linked to their workplace.
Profmed is a well known example of a restricted scheme. Only graduate professionals with a four year or longer qualification who qualify for PPS membership may join it. If you see Profmed mentioned in a list of schemes and wonder why you cannot sign up, that is the reason.
If your employer offers a restricted scheme, it is worth comparing it against the open market before deciding. Restricted schemes can be good value, but they are not automatically the right fit for every family.
Which open medical aid schemes can you join in 2027?
These are the main open schemes accepting members from the public for 2027, with the average contribution increase each scheme has published for 2027. The average is not the increase on your own option, so check the option you are on.

Most of the larger schemes offer entry level, income banded options, for example Discovery KeyCare, Momentum Ingwe and Bonitas BonStart. On these plans your contribution is linked to what you earn, which makes cover more reachable for lower income households. We keep a separate, regularly updated list of medical aid options under R1000, and a full guide on what medical aid costs in South Africa.
What changed in 2025 and 2026?
The past two years brought more movement in the industry than the previous decade, so if you last compared schemes in 2024, the picture has shifted.
Bonitas changed administrators. On 1 June 2026, after 43 years with Medscheme, Bonitas moved its administration to Momentum Health. It is the largest administration transfer in South African history. Bonitas remains its own scheme, but claims, call centres and member systems now run on the Momentum Health platform.
Fedhealth partnered with Sanlam. Fedhealth relaunched its product range in partnership with Sanlam, effective for new members from January 2026. The scheme remains independent and member owned.
Fedhealth and Medshield talks ended. Discussions to amalgamate the two schemes were terminated in November 2025. Both continue as separate open schemes.
Sizwe Hosmed went under curatorship. The scheme was placed under curatorship in late 2025 over solvency concerns and continues to operate under a curator appointed to protect members.
What every scheme must cover (PMBs)
No matter which scheme or plan you choose, the law sets a floor. Every registered medical scheme must pay for Prescribed Minimum Benefits, which cover three things:
- Any emergency medical condition.
- A defined set of 271 conditions, mostly serious hospital level diagnoses.
- 26 chronic conditions on the Chronic Disease List, including common conditions such as diabetes, asthma and hypertension.
This is why even the cheapest registered medical aid plan offers real protection against major health events. It is also one of the key differences between a medical scheme and a health insurance product, which does not have to cover PMBs.
How do you choose between them?
With 16 open schemes and dozens of plans inside each one, comparing on price alone is a mistake. A cheaper plan with the wrong hospital network or a small day to day benefit can cost you far more over a year. Our guide on how to choose a medical aid in South Africa walks through the full process, but the short version is this: match the plan to your health needs, your preferred doctors and hospitals, and your budget, in that order.
Also look beyond the scheme itself. Specialists often charge more than scheme rates in hospital, which is where Gap Cover comes in. It is a separate, inexpensive insurance product that covers the shortfall between what specialists charge and what your scheme pays.
Curemed has been advising South African families since 1992 and is accredited on seven open schemes: Discovery Health, Momentum, Bonitas, Fedhealth, Medihelp, Bestmed and KeyHealth. Because we are an independent brokerage and not tied to any single scheme, a Curemed Advisor can compare plans across all seven schemes for you. Contributions are set by the schemes themselves, and how Curemed is paid is disclosed in full. To compare options for your family, speak to a Curemed Advisor.
