You have medical aid, your procedure has been authorised and the hospital is ready for your admission. It feels like everything is covered until the specialist accounts arrive.
Your surgeon, anaesthetist or radiologist may charge more than the rate your medical scheme is willing to pay. The difference can leave you with a bill running into thousands of rands, even though you have followed the correct process.
This is where medical gap cover can help. It is designed to cover certain shortfalls between what your medical scheme pays and what healthcare providers charge, subject to the benefits, limits, waiting periods and exclusions of your policy.
Here is what South Africans should know before choosing gap cover.
What Is Medical Gap Cover?
Medical gap cover is an insurance product that works alongside your medical aid. It does not replace medical aid and generally cannot be taken out without active membership of a registered medical scheme.
The “gap” is the difference between the amount charged by a medical provider and the tariff covered by your medical scheme.
For example:
• A specialist charges R55,000 for a qualifying procedure.
• Your medical scheme pays R18,000 according to its tariff.
• You are left with a R37,000 shortfall.
Depending on your policy, gap cover may pay a part or all of this shortfall. The final amount will depend on the percentage of the medical scheme tariff covered, the policy’s annual limit and whether the claim meets all the policy rules.
What Medical Gap Cover Is Not
Gap cover is not a medical aid or a replacement for one. It also does not automatically cover every healthcare expense.
It generally does not:
•Pay for ordinary day-to-day GP visits.
•Refill your medical savings account when it is empty.
•Cover every medicine, appliance or treatment.
•Pay a claim simply because your medical scheme rejected it.
•Cover a planned procedure that falls within a waiting period.
In most cases, the medical scheme must first assess the account and pay its portion from the relevant hospital or risk benefit. The gap-cover provider then uses the scheme statement and medical accounts to assess the remaining shortfall.
How Does Gap Cover Work When You Claim?
The claims process will differ slightly between providers, but it usually follows these steps:
1.Get authorisation from your medical scheme before the hospital event or procedure.
2.The hospital and medical professionals submit their accounts.
3.Your medical scheme assesses the claims and pays according to your plan rules.
4.You receive a statement showing what was paid and what remains outstanding.
5.You submit the required medical accounts, scheme statement and completed claim form to your gap-cover provider.
6.The insurer assesses the claim according to your policy benefits and limits.
Kaelo advises that a complete, valid claim may be assessed within approximately seven to 14 working days. Claims must be submitted within the time stated in the policy. For Kaelo Gap Cover, this is generally within six months after the insured event ends.
Keep copies of your hospital authorisation, specialist accounts, hospital account and medical scheme statement. Missing information can delay the process.
What Can Medical Gap Cover Pay For?
Benefits vary between policies, but gap cover may include:
•In-hospital specialist tariff shortfalls.
•Qualifying out-of-hospital procedures paid from the scheme’s risk or hospital benefit.
•Certain co-payments and deductibles.
•Shortfalls caused by medical scheme sub-limits.
•Oncology tariff shortfalls, co-payments or sub-limits.
•Emergency casualty treatment following an accident.
•Certain penalties for voluntarily using a non-network hospital.
•Specified maternity-related shortfalls.
Not every benefit is available on every option. A more affordable plan may focus mainly on specialist tariff shortfalls, while a more comprehensive option may add co-payment, oncology and sub-limit protection.
Always read the policy schedule and full wording before applying. The summary of benefits is useful, but the policy document determines what is covered.
Why Do Medical Aid Shortfalls Happen?
Medical schemes pay according to their own tariffs and the benefits available on your chosen option. Healthcare professionals in private practice may charge above those rates.
Shortfalls often involve:
•Surgeons.
•Anaesthetists.
•Obstetricians.
•Radiologists and pathologists.
•Physiotherapists involved in a hospital event.
They can arise during procedures such as C-sections, scopes, spinal surgery, tonsillectomies and joint replacements.
Before a planned procedure, ask every healthcare provider for a written quotation. Send the relevant procedure codes to your medical scheme and ask what it will pay. This gives you a clearer view of any possible shortfall before admission.
Waiting Periods and Exclusions
Taking out gap cover shortly before a planned procedure will not necessarily cover that event.
Kaelo’s 2026 Gap Optima summary lists:
•A three-month general waiting period.
•A 12-month condition-specific waiting period.
Claims linked to accidental injuries may be treated differently, subject to the policy. If you move directly from another gap-cover provider, the waiting periods you have already completed may also be taken into account. Avoid a break in cover and provide proof of your previous policy when applying.
Common exclusions may include claims rejected by your medical scheme, infertility treatment, specialised dentistry, external prostheses, take-home medicine and treatment outside South Africa. The exact exclusions depend on the policy, so do not rely on a general list when making a healthcare decision.
Who Should Consider Gap Cover?
Gap cover may be worth considering if:
•You are on a hospital plan that pays a lower percentage of the scheme tariff.
•You could not comfortably pay a specialist shortfall from your savings.
•You are planning a family or may need surgery in future.
•Your medical scheme applies co-payments or strict sub-limits.
•You want additional financial protection for qualifying oncology treatment.
Even members on more comprehensive medical aid options can face shortfalls. The key is to compare your existing benefits with the protection offered by the gap-cover policy.
What Should You Compare Before Choosing a Plan?
Do not choose a policy based on the monthly premium alone. Check:
•The additional percentage of the medical scheme tariff covered.
•The overall annual limit per insured person.
•Co-payment and deductible benefits.
•Cover for shortfalls caused by sub-limits.
•Oncology benefits.
•Qualifying out-of-hospital procedures.
•Network-hospital penalty benefits.
•Waiting periods and transfer concessions.
•Age limits and the definition of family members.
•Important exclusions and claim-submission deadlines.
For 2026, Kaelo Gap Optima provides up to an additional 600% of the medical scheme rate for qualifying tariff shortfalls, subject to policy terms and the overall annual limit. It also includes specified co-payment, sub-limit, oncology, casualty and family benefits.
Limits and benefits are reviewed periodically, so always confirm the current policy schedule and personalised premium before signing up.

The Bottom Line
Medical aid is essential, but it does not guarantee that every private healthcare bill will be paid in full. If a specialist charges more than your scheme tariff, you could be responsible for the difference.
The right gap-cover policy can soften that financial blow. Compare the tariff percentage, annual limit, co-payment benefits, waiting periods and exclusions against your medical aid option before deciding.
Most importantly, do not wait until a procedure is already booked. Gap cover works best when it is in place before you need it.
Protect yourself from unexpected medical shortfalls. Apply for Medical Gap Cover through Mondo and get help choosing suitable cover for your needs and budget.
Frequently Asked Questions
Is gap cover the same as medical aid?
No. Medical aid funds eligible healthcare costs according to your plan, while gap cover insures certain shortfalls left after the scheme has paid. Gap cover cannot replace medical aid.
Do I need medical aid to get gap cover?
Yes. You generally need active membership of a registered medical scheme. Mondo currently requires at least one month of medical aid membership.
Will gap cover pay if my medical aid pays nothing?
Usually not. Most tariff-shortfall claims require the medical scheme to pay part of the relevant account from its hospital or risk benefit. Some separately defined benefits may work differently.
Does gap cover have waiting periods?
Yes. General and condition-specific waiting periods may apply. These can affect planned procedures, maternity and pre-existing conditions, so confirm them before joining.
Can one policy cover my family?
Family cover may include the policyholder, a qualifying spouse and eligible children. Mondo advertises family cover for children up to age 25, subject to the policy rules.
