OneHealth Medical Health Scheme
About OneHealth Medical Scheme
About OneHealth Medical Scheme
The Scheme exists for the benefit of all our members and this guides everything we do. We apply social solidarity principles to balance the needs of individual members with the collective wellbeing of the Scheme.
As a non-profit medical scheme in South Africa, OneHealth Medical Scheme operates according to social solidarity principles, whereby the Scheme pools member contributions and manages these to fund member healthcare equitably.
Working to care for and protect our members
Our goal is to provide support for our members in the times when it is needed most.
Who We Are
OneHealth Medical Scheme is the largest open medical scheme in South Africa, with an open market share of 57.6% (based on beneficiaries, according to the CMS Annual Report for the year ended December 2021) and covering 2 810 992 beneficiaries at 31 December 2022.
OneHealth is a non-profit entity governed by the Medical Schemes Act 131 of 1998, as amended, and regulated by the Council for Medical Schemes (CMS). It is a registered open medical scheme that any member of the public can join, subject to the Scheme rules.
The Scheme belongs to its members and an independent Board of Trustees (the Trustees or the Board) oversees its activities. The Scheme outsources its administration and managed care functions to OneHealth (Pty) Ltd through a formal contractual arrangement.
Why Join OneHealth?
Quality of care is key to our membership proposition
One of the Scheme's strategic priorities is to drive value-based healthcare. Placing our members at the centre of care, this approach reimburses providers based on health outcomes and not only the volume of services they deliver. It gives our members access to programmes and providers that are committed to continuous improvement in quality care.
With OneHealth, the Scheme strives to ensure that our members have access to the safest, most efficient and effective healthcare available in South Africa, through many quality of care initiatives and innovations, which are closely monitored by the Scheme on an ongoing basis. The Scheme also empowers our members with information relevant to their needs.
Our purpose is to care for our members' health and wellness by engaging the brightest minds and innovative solutions to provide access to affordable, equitable and quality, value-based healthcare that meets their needs now and sustainably into the future.
Our vision is to be the best medical Scheme in the country. In the interests of our members we will always pursue excellence, leveraging the Vested outsourcing model to lead healthcare innovation and create value. We will work closely with our regulator, our Administrator and Managed Care Provider, and the industry to shape an inclusive and complete healthcare system in South Africa.
The Scheme's support of OneHealth's shared value model, which engages stakeholders in working together towards better healthcare access and affordability, also contributes to positive regulatory reform and extends the Scheme's influence in driving beneficial change in our sector.
We'll be here for you
Financial strength and sustainability are key factors to consider when selecting a medical scheme. Sound financial control and risk management enables the Scheme to maintain its required solvency reserve levels, which ensure its ability to pay claims even when they are unexpectedly high.
We make sure your investment in membership takes care of you
The Scheme's income is derived only from member contributions and investment returns. The Scheme pools all contributions to fund members' claims, and any surplus funds are transferred to Scheme reserves for the security and benefit of members.
In setting member contributions for each year, the Scheme aims to ensure sufficient contribution income to pay all claims, and to generate a modest surplus to meet regulated solvency requirements and maintain a cushion against unexpected cost increases. This accords with the fundamental operating principles of a non-profit organisation that must meet the claims needs of its members as well as maintaining a statutory level of reserves.
A portion of OneHealth's income (shown alongside) is used to fund activities that benefit our members and ensure the Scheme's sustainability. These activities include administration, managed care, financial advisers and the daily operations of the Scheme.
Apart from the reserves and these activities, the Scheme's entire income is used to fund claims.
What is medical aid?
Medical aid in South Africa provides financial cover for medical expenses for members who pay a monthly contribution for this cover.
These contributions are paid to medical aid schemes (including OneHealth Medical Scheme) and are pooled and safeguarded. These schemes are operated on a not-for-profit basis.
Medical aid covers members' healthcare costs such as hospitalisation, treatments and medicine. These costs are covered according to the rules of the medical scheme and the member’s medical aid plan type. These rules ensure that members are fairly cared for.
All medical schemes in South Africa are governed in accordance with the Medical Schemes Act 131 of 1998, and are regulated by the Council of Medical Schemes.
How medical schemes work
A medical scheme is a non-profit organisation, governed by a board of trustees, and must be registered with the Council for Medical Schemes.
This means it does not have shareholders or pay dividends and that the Scheme's income can only ever be derived from member contributions and investment returns. The Scheme pools all members' contributions to fund members' claims, and any surplus funds are transferred, in accordance with regulations, to Scheme reserves for the security and benefit of members. A medical scheme therefore does not make any profits.
Schemes exist for their members as all funds are pooled and safeguarded, to be used to pay claims in accordance with the scheme's rules, and ensure that all members are equitably and fairly cared for (relative to their choice of benefit plan).
All medical schemes in South Africa operate in accordance with the Medical Schemes Act 131 of 1998, and are regulated by the Council for Medical Schemes.
What does 'open medical scheme' mean?
Restricted (closed) medical schemes are administered on behalf of companies for their staff and their families, or can be joined by people working in a particular industry.
Open schemes, on the other hand, are open to the public and anyone can join if they are over 18, not currently a member of another medical scheme and can afford to pay the monthly contributions.

Why does OneHealth (Pty) Ltd administer the Scheme?
OneHealth Pty (Ltd) provides administration and managed care services to OneHealth Medical Scheme. Managed care is rules based programmes that use clinical and financial risk assessments to provide appropriate, quality and value-focussed healthcare services. Schemes can either outsource its administration or perform this function in-house. The medical scheme environment is complex. It requires significant expertise to manage a scheme effectively, to provide the infrastructure required and to make sure it meets the needs of all its stakeholders, while keeping that scheme affordable, both now and into the future.Most schemes in South Africa use external administration organisations to provide these expert services to their members. It is essential that schemes and their administrators work with the same objectives in mind - to care for their members at an acceptable cost - even though administrators are able to make a profit, unlike schemes.To ensure that this is the case, OneHealth Medical Scheme has implemented a world-class outsourcing model called Vested Outsourcing to govern its relationship with OneHealth (Pty) Ltd.Medical scheme administrators charge administration fees to manage aspects such as:- Risk
- Benefit design
- Underwriting
- Service
- Collection of contributions
- Processing of claims
Terminology
A
Above Threshold Benefit (ATB)
The Above Threshold Benefit (ATB) gives you extra cover when your claims add up to a set amount called the Annual Threshold, if you are on an Executive, Comprehensive or Priority plan.
Once all the claims you have sent to us add up to the Annual Threshold, we pay the rest of your claims from the Above Threshold Benefit (ATB), at the OneHealth Rate (OHR) or a portion of it. The Executive and Comprehensive plans have an unlimited Above Threshold Benefit (ATB), and the Priority plans have a limited ATB.
Read more about the ATB.
Additional Disease List (ADL)
Once approved on the Chronic Illness Benefit (CIB), you have cover for medicine for additional diseases that we cover over and above the 27 chronic conditions if you're on our Executive or Comprehensive plans. The conditions are:

View the Delta Hospital Network.
Designated Service Provider (DSP)
A designated service provider is a healthcare provider (such as a doctor, specialist, allied healthcare professional, pharmacist or hospital) that is a medical scheme's first choice when members need diagnosis, treatment or care for a Prescribed Minimum Benefit condition.
If you choose not to use a designated service provider, you may have to pay a portion of the bill yourself. This could either be a percentage co-payment or the difference between the OneHealth Rate and that charged by the healthcare provider you used.

Limits
Most in-hospital and out-of-hospital healthcare benefits do not have an upper limit, but some healthcare services, such as dentistry and optometry, have yearly limits that apply. It's important to familiarise yourself with these limits and to keep track of your use of them. OneHealth Medical Scheme members can do this by logging in to the Discovery website.
M
Medical Savings Account (MSA)
On the Executive, Comprehensive, Priority and Saver plans, the Medical Savings Account (MSA) is an amount that is allocated to you at the beginning of each year or when you join the Scheme. You pay this amount back in equal portions as part of your monthly contribution. We pay your day-to-day medical expenses such as GP and specialist consultations, acute medicine, radiology and pathology from the available funds allocated to your MSA. Any unused funds will carry over to the next year. Should you leave the Scheme or change your plan partway through the year and have used more of the funds than what you have contributed, you will need to pay the difference to us. Learn more about the Medical Savings Account.
Medicine list or formulary
This is a list of approved medicine we pay for in full. This list includes an extensive range of high-quality medicine to make sure you always have the option of full cover.
View any one of our medicine lists (formularies) here.
What if I suffer side effects from medicine on the formulary?
If this happens, or if substituting your current medicine with medicine on the formulary has a negative effect on your health, you and your doctor can put your case to us and ask us to pay for your medicine.
The forms to appeal are available here.
N
Networks
Some plans, benefits and healthcare services require you to use the Scheme's network providers. Use our extensive networks of healthcare providers to get full cover.

P
Payment arrangement
The Scheme has entered into payment arrangements with various healthcare professionals that have agreed to charge at the OneHealth Rate. You benefit from access to the broadest range of doctors, which represents over 90% of our members' doctor interactions. If you use healthcare professionals that we don't have payment arrangements with, we will pay at the rate applicable to your chosen plan and you may have a co-payment.
Prescribed Minimum Benefits (PMBs)
In terms of the Medical Schemes Act of 1998 (Act No. 131 of 1998) and its Regulations, all medical schemes have to cover the costs related to the diagnosis, treatment and care of:
- An emergency medical condition
- A defined list of 270 diagnoses
- A defined list of 26 chronic conditions
To access Prescribed Minimum Benefits (PMBs), there are rules that apply:
- Your medical condition must qualify for cover and be part of the defined list of Prescribed Minimum Benefit (PMB) conditions.
- The treatment needed must match the treatments in the defined benefits.
- You must use designated service providers (DSPs) in our network. This does not apply in emergencies. However even in these cases, where appropriate and according to the rules of the Scheme, you may be transferred to a hospital or other service providers in our network, once your condition has stabilised.
If your treatment doesn't meet the above criteria, we will pay up to 80% of the OneHealth Rate. You will be responsible for the difference between what we pay and the actual cost of your treatment.
What is an emergency
An emergency medical condition, also referred to as an emergency, is the sudden and, at the time unexpected onset of a health condition that requires immediate medical and surgical treatment, where failure to provide medical or surgical treatment would result in serious impairment to bodily functions or serious dysfunction of a bodily organ or part or would place the person's life in serious jeopardy. An emergency does not necessarily require a hospital admission. We may ask you for additional information to confirm the emergency.
For more information, read our Guide to Prescribed Minimum Benefits, Prescribed Minimum Benefit treatment guidelines, Guide to Prescribed Minimum Benefits for in-hospital treatment and Prescribed Minimum Benefit list of conditions.
S
Self-payment Gap (SPG)
The Self-payment Gap (SPG) is applicable to plans that have a Medical Savings Account, and refers to a temporary gap in cover when you run out of funds in your Medical Savings Account but have not yet reached your Annual Threshold.
You must still send claims to us so that we know when to start paying from your Above Threshold Benefit (ATB).
Read more about the SPG.
Smart Hospital Network
If you are on the Smart Plan, this is a network of specific providers, both in hospital and out of hospital, which you must use to be covered.
