Medical aid premiums in South Africa continue to rise year on year, with 2026 increases ranging from 5% to over 10% depending on the scheme. But here’s what many members don’t realise: higher premiums don’t automatically mean better protection. In fact, as schemes manage costs internally, the gap between what they pay and what specialists actually charge often widens. This is where gap cover becomes essential.
Why Higher Premiums Don’t Mean Better Coverage
Medical schemes face mounting pressure from medical inflation, claims growth, and regulatory requirements. The Council for Medical Schemes (CMS) recommended that 2026 contribution increases be limited to 3.3% plus reasonable utilisation estimates—yet most major schemes have exceeded this, with contributions rising at CPI plus 4 to 5 percentage points.
To keep contribution increases manageable, many schemes adjust their tariff structures, tighten benefit limits, or negotiate harder with hospital networks.
The result? Your monthly premium goes up, but your scheme may still only reimburse at 100% or 200% of the scheme tariff, while specialists routinely charge 300% to 500% of that rate. The shortfall still lands on you.
The Growing Shortfall Problem
Medical scheme tariffs and specialist fees are not the same thing. Schemes set their own reimbursement rates, but specialists are not bound by these. A surgeon, anaesthetist, or physician can charge whatever the market allows.
For example, if your scheme pays R15,000 for a procedure but your specialist bills R35,000, you face a R20,000 shortfall. This is an in-hospital expense your medical aid simply won’t cover regardless of how much your premium increased this year.
As medical inflation outpaces scheme rate adjustments, these shortfalls are becoming larger and more common.
2026 Scheme Increases at a Glance
Comparing premium increases across schemes shows the varied adjustments for 2026:
| Scheme | Weighted Average Increase |
| Discovery Health | 7.2% |
| Bonitas | 8.8% |
| Medihelp | 8.46% |
| Bestmed | 6.8% |
| Momentum | 9.9% |
| Fedhealth | 9.6% |
| Sizwe Hosmed | 19.15% (contribution) |
While these percentages reflect contribution changes, they don’t reveal what’s happening to tariff rates, sub-limits, or co-payment structures, factors that directly affect your shortfall exposure.
How Gap Cover Protects You
Gap cover is a short-term insurance product that pays the difference between what your medical scheme reimburses and what healthcare providers charge for in-hospital treatment. It doesn’t reduce your monthly medical aid premium, but it can save you tens of thousands of rands when you’re hospitalised.
Benefits include:
- Specialist shortfall cover – Pays the gap when doctors charge above scheme tariff
- Co-payment cover – Covers certain in-hospital co-payments imposed by your scheme
- Internal limit shortfalls – Assists when your scheme’s internal limits fall short of actual costs
With premiums rising and shortfall risk increasing, gap cover offers financial protection that your medical aid alone cannot provide.
Consider Gap Cover With Your Medical Aid
Rising medical aid premiums don’t guarantee better coverage—they often mask tightening benefits and growing shortfalls. As schemes adjust their structures to manage costs, the gap between what they pay and what you’re billed continues to widen.
Gap cover bridges that gap. For a fraction of the cost of your medical aid contribution, it protects you from unexpected in-hospital expenses that could otherwise run into tens of thousands of rands.
If you’re reviewing your medical aid for 2026, make sure gap cover is part of the conversation.
