Gap cover explained for South Africa
By Naledi Mokoena · 6 min read · Updated 24 June 2026
Gap cover is a separate insurance product that pays the shortfall between what a specialist or hospital charges and what your medical aid pays at its scheme rate, because specialists can charge several times that scheme rate, and gap cover bridges the difference to protect you from a large out-of-pocket bill after a procedure.
Gap cover is not medical aid and does not replace it. It sits on top of your scheme, and it is regulated as insurance with its own limits and rules, including an annual cap set by regulation.
This guide explains how gap cover works, what to look for and whether you need it.
What gap cover actually does
Your medical aid pays in-hospital specialists at a scheme rate. Many specialists charge more than that rate, sometimes 200% to 500% of it. The difference is the gap. Gap cover pays that shortfall, up to its own limits, so you are not left with a large bill after surgery. It can also cover co-payments and sub-limit shortfalls on some policies. It only works alongside an active medical scheme.
What to look for in a gap policy
- Cover multiple: how many times the scheme rate it pays up to.
- Co-payment and sub-limit cover: whether it covers scheme co-payments and sub-limits.
- Waiting periods: typically a general waiting period and a longer one for some conditions.
- Age limits and loadings: older applicants may face higher premiums.
- Annual limit: gap cover has a regulated overall annual limit per person, which rises with inflation each year.
Who needs gap cover
Gap cover makes most sense if you use a plan that pays specialists at a basic scheme rate and you want protection from specialist shortfalls, or if you are likely to have surgery, a baby or specialist treatment. Members on top comprehensive plans with high specialist cover may need it less. Weigh the modest monthly premium against the risk of a large shortfall.
Gap cover is not medical aid
Gap cover cannot stand alone. It only pays alongside an active medical scheme and does not cover the base hospital bill, day-to-day costs or PMBs. Do not buy gap cover instead of medical aid. Because it is insurance, complaints go to the insurance ombud, not the Council for Medical Schemes.
The rules and your rights
Gap cover is regulated under insurance demarcation rules, with an annual cover limit per insured person set by regulation. Read the policy waiting periods and exclusions carefully. For your underlying medical scheme, the CMS at medicalschemes.co.za remains the regulator.
Frequently asked questions
What is gap cover?
Gap cover is a separate insurance product that pays the shortfall between what a specialist or hospital charges and what your medical aid pays at its scheme rate. It protects you from large out-of-pocket bills after surgery or specialist treatment.
Do I need gap cover?
You likely benefit from gap cover if your plan pays specialists at a basic scheme rate and you want protection from shortfalls, or if surgery or a baby is likely. Members on top comprehensive plans with high specialist cover may need it less.
Is gap cover the same as medical aid?
No. Gap cover is insurance that only works alongside an active medical scheme. It does not cover the base hospital bill, day-to-day costs or PMBs. Never buy gap cover instead of medical aid; it complements, not replaces, your scheme.
What is the best gap cover in South Africa?
The best gap cover depends on your scheme, age and needs. Compare the cover multiple, co-payment and sub-limit cover, waiting periods and annual limit. A higher cover multiple protects against larger specialist shortfalls. Match it to your medical aid plan.
Is there gap cover with no waiting period?
Some policies waive waiting periods in defined situations, such as moving from an existing gap policy. Most apply a general waiting period and a longer one for certain conditions. Check the specific policy terms before assuming immediate cover.
Is gap cover limited each year?
Yes. Gap cover has a regulated overall annual limit per insured person, which rises with inflation each year. Beyond that limit you carry the shortfall yourself. Read the policy for the current annual limit and any sub-limits.
