What is Gap Cover and why do you need it?

What is Medical Gap Cover

Ever felt that sinking feeling when your Medical Aid doesn't cover the full cost of a procedure? A R90,000 surgery where your Medical Aid only pays R30,000 leaves you with a R60,000 bill to cover yourself.

Medical expenses in South Africa can be steep, and while Medical Aid helps, it doesn't always cover the full amount. That's where Gap Cover steps in: a financial safety net designed to keep you from paying large out-of-pocket in-hospital expenses.

But what exactly is Gap Cover, how does it work, and why should you consider it? Let's break it down in simple terms.

Hippo's quick bites:

  1. Gap Cover is short-term insurance that pays the difference between what your Medical Aid covers and what your specialist actually charges.

  2. Providers often charge well above Medical Aid tariffs, sometimes by hundreds of a percent, so even a good Medical Aid plan can leave you with a large shortfall.

  3. Gap Cover closes that gap, but only works alongside Medical Aid, not instead of it.

Understanding Medical Aid rates

Medical Aid providers set a rate, called the medical scheme tariff (MST), that they're willing to pay for different treatments and procedures. The problem is that many healthcare providers charge well above these rates, sometimes up to 500% more. Medical Aids in South Africa typically cover between 100% and 300% of the MST, depending on your plan.

Let's say your Medical Aid covers an in-hospital procedure at R101,000, but the total cost is R153,000. Without Gap Cover, you'd be responsible for paying the remaining R52,000 out of pocket.

Even a top-tier Medical Aid plan can leave you with co-payments and sub-limits that add up to a hefty bill. This is where Gap Cover can make a real difference, so you're not caught off guard by unexpected expenses.

Something to Fill the Gap

Gap Cover is a short-term insurance product that fills the gap between what your Medical Aid pays and what your healthcare provider charges for in-hospital procedures. It's designed to stop you having to dip into savings or take on debt just to afford medical treatment.

Benefits vary by provider and can include:

  • Paying the difference between what your specialist charges and what your Medical Aid covers, often up to 500% above MST

  • Covering additional fees for procedures such as MRI or CT scans, which many Medical Aids only partially cover

  • Helping with costs when Medical Aids impose limits on certain treatments, like internal prosthetics or ICU stays

  • Covering shortfalls in chemotherapy, radiation therapy and other cancer treatments

  • Covering emergency treatments that may not be fully covered by Medical Aid

  • Trauma counselling, maternity cover or lump-sum pay-outs for serious illness, depending on the provider

Gap Cover isn't a replacement for Medical Aid. It works alongside it, so if you don't have Medical Aid, you won't qualify for Gap Cover.

Unpacking Medical Aid benefits from leading providers

Medical Aid is often sold as a simple idea: you contribute monthly, and your healthcare is covered. That’s the theory, anyway. In practice, it’s the benefits that shape your real experience – and those can differ much more than people expect. If you’re reviewing your options or signing up for a Medical Aid for the first time, it helps to look beyond what’s included and focus on what those benefits actually mean in real terms.
