Most medical scheme members have heard of Prescribed Minimum Benefits. Very few know exactly what those words mean — or how to use them. That is not an accident. Complexity favours the scheme; clarity favours you. This article exists to level that playing field.
The Legal Foundation
Prescribed Minimum Benefits — PMBs — are not a marketing commitment or an optional benefit enhancement. They are a statutory obligation imposed on every registered medical scheme in South Africa by Section 29(1)(o) of the Medical Schemes Act 131 of 1998, read together with the Regulations promulgated under GN R1262. No scheme may lawfully exclude PMB conditions from cover, regardless of option, regardless of fund rules, and regardless of available benefits.
The Act does not invite compliance — it compels it. Any scheme that attempts to limit, exclude or dilute PMB cover without lawful basis is in contravention of the Medical Schemes Act.
270 Conditions and 25 Chronic Diseases
PMBs encompass three distinct categories of cover. First, any emergency medical condition — defined in the Regulations as a sudden and, at the time, unexpected onset of a health condition that requires immediate medical treatment. Second, a defined list of 270 Diagnosis Treatment Pairs (DTPs) covering a broad spectrum of clinical conditions, from appendicitis to cataracts to HIV/AIDS. Third, and critically, the 26 Chronic Disease List (CDL) conditions — commonly cited as 25, though the regulatory count includes sub-classifications — covering conditions such as diabetes, hypertension, asthma, epilepsy, coronary artery disease, and multiple sclerosis, among others.
Each DTP specifies not merely the diagnosis, but the treatment the scheme is required to fund. This matters enormously in practice. A scheme that funds the diagnosis but not the treatment, or that funds the generic equivalent but refuses the clinically appropriate branded medicine, may well be in breach of its PMB obligations.
No Co-Payment When You Follow the Rules
This is where most disputes arise, and where most members are incorrectly billed. The Regulations are explicit: when a member receives PMB-level care from the scheme's Designated Service Provider (DSP), the scheme may not impose a co-payment. The DSP arrangement is the scheme's contractual mechanism for cost management. If you use their preferred provider for a PMB condition, cost-sharing does not apply.
Where a member chooses a non-DSP provider, the scheme may limit its liability to the cost it would have incurred at the DSP. The member may then face a shortfall — but this is a shortfall arising from provider choice, not from the PMB obligation itself. These two scenarios are frequently conflated by schemes, to the member's financial detriment.
If you were admitted to hospital for a PMB condition, treated at a DSP, and then billed a co-payment — that billing warrants a formal challenge. MediCheck regularly overturns these charges.
When Schemes Get It Wrong
Common PMB disputes that MediCheck manages include schemes that apply benefit limits to PMB conditions (unlawful), schemes that refuse to authorise PMB treatment on the basis that the member's chronic benefit is exhausted (irrelevant — PMBs are funded separately), schemes that insist on formulary medicines where the clinically appropriate medicine is a non-formulary item (challengeable on substitution grounds under Regulation 15(I)), and schemes that apply a co-payment to DSP-provided PMB treatment (a direct contravention of the Regulations).
Each of these scenarios is a regulatory compliance failure. Members have the right — and in most cases the practical ability, with correct advocacy — to have such decisions overturned.
MediCheck Tip: If your scheme has denied, co-payment-loaded, or limited treatment for a condition you believe falls within the PMBs, contact MediCheck before paying the bill. The regulatory framework is on your side — you simply need to know how to use it.
