Hospital Pre-Authorization Denied in South Africa

Pre-authorisation (also called prior authorisation or pre-auth) is one of the most common points of friction between South African medical scheme members and their schemes. Being told that a planned hospitalisation or procedure will not be covered — before you even walk through the hospital door — is stressful and can lead to harmful delays in care. Here is what you need to know about your rights and how to challenge a pre-auth denial.

What Is Pre-Authorisation?

Pre-authorisation is a process where a medical scheme reviews a planned hospitalisation, surgical procedure, or high-cost treatment before it takes place. The scheme's clinical team assesses whether the procedure is:

• Clinically appropriate for your diagnosed condition
• Being performed at an appropriate level of care
• Medically necessary (not cosmetic or elective in the luxury sense)
• Covered under your plan's benefits

Most schemes require pre-auth for:

• All elective hospital admissions
• Major surgical procedures
• Planned diagnostic procedures (e.g., MRI, CT scan, colonoscopy)
• Oncology treatment initiation
• Mental health admissions
• Rehabilitation admissions

Emergency admissions do not require pre-authorisation. If you go to an emergency department with a life-threatening or acute condition, the scheme must cover emergency stabilisation — pre-auth cannot be required for a genuine emergency.

Why Do Schemes Deny Pre-Authorisation?

Medical necessity not established: The scheme's clinical reviewers do not agree that the procedure is warranted at this time. They may request additional clinical documentation before approving.

Insufficient documentation: The referring specialist has not submitted enough clinical information. The scheme may not deny outright but request more — which is effectively a delay.

Procedure not covered on your plan: Some procedures are explicitly excluded (e.g., fertility treatment, certain cosmetic reconstructions) or require an upgraded plan.

Out-of-network provider: You have requested pre-auth for a hospital or surgeon not on the scheme's Designated Service Provider (DSP) list. The scheme may refuse pre-auth or offer to fund at a reduced rate.

Benefit exhaustion: You have reached your annual hospitalisation limit (this is uncommon but can apply on very basic plans — and does not apply to PMBs).

Alternative treatment proposed: The scheme agrees you need treatment but proposes a less invasive or less expensive option first.

Pre-Authorisation and PMBs

A crucial point: if the procedure or hospitalisation is for a Prescribed Minimum Benefit (PMB) condition, the scheme cannot refuse pre-authorisation on the basis of cost or plan level. They may manage the setting of treatment (e.g., requiring use of a DSP) but they cannot deny the treatment itself.

If the scheme denies pre-auth for a PMB procedure, they are potentially in breach of the Medical Schemes Act 131 of 1998. This is a strong basis for a formal complaint to the CMS.

How to Appeal a Pre-Authorisation Denial

Step 1 — Request the denial in writing

The scheme must provide a written reason for the pre-auth denial. Do not accept a verbal "no" — insist on written documentation detailing the clinical or administrative reason.

Step 2 — Work with your doctor

Your specialist must submit a comprehensive motivation. This should include:

• The specific diagnosis (ICD-10 code)
• Clinical findings supporting the need for the procedure
• Why conservative or alternative management is insufficient
• The clinical risk of delaying treatment
• Reference to any relevant PMB DTP if applicable

Step 3 — Submit a formal written appeal

Address the appeal to the scheme's clinical review team and principal officer. Include:

• Member details and claim/pre-auth reference
• Doctor's motivation letter and supporting clinical records
• Clear statement of why the denial is incorrect
• PMB reference if applicable (cite the Medical Schemes Act and the specific DTP)

Request a peer-to-peer review — where your specialist speaks directly with the scheme's medical reviewer. This process often resolves clinical disputes more quickly than a paper appeal.

Step 4 — Urgent appeals

If the pre-auth denial creates a risk to your health — for example, a cancer procedure is delayed, or a cardiac procedure is needed urgently — you can escalate immediately to the CMS and request urgent intervention. The CMS can expedite investigations where health risk is evident.

Step 5 — CMS complaint

For non-urgent cases: if the scheme does not resolve the matter within 30 days, file a complaint at medicalschemes.com.

What Happens if You Proceed Without Pre-Auth?

For elective procedures: the scheme may reduce payment significantly or decline altogether. This leaves you with a large hospital bill.

For emergency admissions: schemes cannot penalise you for failing to obtain pre-auth for a genuine emergency. Cover PMB emergency care must be provided.

If you believe your admission was clinically urgent but the scheme classified it as elective, document this carefully in your appeal. Include the emergency department records, the admission notes, and your doctor's statement about the urgency of admission.

Practical Tips

• Call your scheme as soon as a hospitalisation is planned — even if you have a few weeks before the procedure
• Ask the treating specialist's rooms to handle pre-auth submission — most do this routinely
• If pre-auth is denied, ask specifically whether additional documentation would lead to reconsideration
• Keep the pre-auth approval number once approved — and confirm in writing what is covered (the facility, the procedure, and the treating clinician)
• A "conditional approval" with exclusions is not a full approval — clarify what is and is not covered before proceeding
