Cancer Treatment Denied by SA Medical Scheme

A cancer diagnosis is devastating on its own. Discovering that your medical scheme has denied or limited funding for your treatment adds an unbearable layer of stress. The good news is that cancer is a Prescribed Minimum Benefit (PMB) in South Africa — meaning your medical scheme has a legal obligation to fund your treatment, and denials can be challenged.

Cancer as a Prescribed Minimum Benefit

Under the Medical Schemes Act 131 of 1998 and the Prescribed Minimum Benefits Regulations, cancer is listed both as a Chronic Disease List (CDL) condition and within numerous defined diagnosis-treatment pairs (DTPs).

This means:

• Your scheme must fund cancer treatment regardless of which plan you hold
• Annual benefit limits on cancer benefits cannot override PMB entitlement
• Your scheme cannot deny cancer treatment on the basis of benefit exhaustion
• Emergency cancer-related presentations (e.g., acute complications) must always be covered

The PMB cancer benefit covers "the defined minimum treatment" — meaning treatment that is medically appropriate and aligned with established clinical protocols (e.g., SASMO, NCCN guidelines for certain cancers). Experimental or unproven treatments may not be covered at PMB level, but all standard oncology regimens are.

Why Medical Schemes Still Deny Cancer Claims

Even though cancer is a PMB, denials happen — frequently. Common denial scenarios include:

Oncology benefit exhaustion: Many schemes have a specific annual oncology benefit (e.g., R150,000 per year). When this is reached, further claims are declined. However — and this is critical — the PMB entitlement for cancer treatment does not have an annual rand limit. If the scheme's oncology sub-limit is exhausted, the PMB must still apply to defined treatment. This is a frequently litigated point at the CMS.

Non-DSP specialist or facility: The scheme requires cancer treatment at a Designated Service Provider. If you are receiving chemotherapy from an oncologist not on their panel, they may deny or reduce payment. In many cases, the specialist you are referred to is simply the most appropriate one available — document why you are using this provider.

Off-protocol treatment: The scheme's clinical team may decide that the specific chemotherapy regimen your oncologist has prescribed deviates from their defined protocol. They may offer to fund an alternative protocol instead. If your oncologist disagrees, a peer-to-peer review between your doctor and the scheme's medical advisor is the next step.

Targeted therapies and biologics denied: Modern oncology increasingly relies on targeted biological therapies — drugs like trastuzumab (Herceptin), bevacizumab (Avastin), or pembrolizumab (Keytruda). These are expensive and often subject to strict prior authorisation criteria. Schemes routinely require proof of specific molecular markers (e.g., HER2 positive for trastuzumab) before approving.

Reconstruction surgery denied: Post-mastectomy breast reconstruction is sometimes denied as "cosmetic." This is incorrect — breast reconstruction following cancer treatment is a therapeutic procedure and should be covered.

Palliative care disputes: Schemes may dispute the extent or setting of palliative care — particularly home-based palliative services.

How to Appeal a Cancer Treatment Denial

Step 1 — Confirm the PMB basis

Identify the relevant CDL condition (cancer) and any applicable DTP on the CMS PMB schedule. Most solid tumour and haematological cancers are covered.

Step 2 — Oncologist's detailed motivation

Your treating oncologist must write a comprehensive motivation that includes:

• Exact diagnosis with histological confirmation and staging
• The specific treatment being requested
• The clinical guidelines or protocols supporting this treatment (e.g., NCCN, ESMO, SASMO)
• Why alternative or lesser treatments are not appropriate
• The expected benefit to the patient
• Reference to the PMB entitlement under the Medical Schemes Act

Step 3 — Formal written appeal to the scheme

Address to the scheme's oncology case management team and principal officer. Explicitly state that cancer is a PMB condition and that the scheme's annual oncology benefit limit cannot override the PMB mandate. Request written clinical reasons from the scheme's reviewer.

Step 4 — Request peer-to-peer review

Ask that your oncologist be able to speak directly with the scheme's medical reviewer. This is particularly important for off-protocol or targeted therapy denials.

Step 5 — CMS complaint

If unresolved within 30 days — or if treatment delays create a health risk:

• File urgently at medicalschemes.com
• Email: complaints@medicalschemes.com
• Request urgent intervention given the oncology context

The PMB Oncology Cap Issue

A major area of dispute: schemes argue that PMB cancer cover is limited to the "cost-effective treatment" as defined in their protocols. Members argue that PMB mandates full coverage of medically appropriate treatment. The CMS has consistently ruled that schemes must fund medically appropriate treatment for PMB conditions, even if it exceeds their internal cost protocols.

If your scheme denies cancer treatment citing cost protocols or internal clinical criteria, cite the CMS's historical PMB cancer rulings in your appeal.

Practical Steps for Cancer Patients

• Register your cancer diagnosis with the scheme as a CDL condition immediately — this unlocks the PMB chronic benefit
• Keep all histology, staging reports, and oncology treatment plans — these are critical for pre-auth and appeals
• Ask your oncologist's rooms to manage the pre-auth process — most oncology practices do this routinely
• Do not delay treatment while waiting for scheme authorisation — if the scheme does not respond within a reasonable time, proceed and document the urgency
