Claim Denied Due to Medical Scheme Waiting Period

Receiving a medical scheme claim denial because of a waiting period — particularly when you are dealing with an acute health crisis — is one of the most frustrating experiences a new scheme member can face. Understanding which waiting periods are legal, which are not, and how to challenge an unfair one can make a significant difference.

Types of Waiting Periods in South African Medical Schemes

The Medical Schemes Act 131 of 1998 allows medical schemes to impose waiting periods under specific conditions. There are two main types:

General waiting period: A 3-month period from the date of scheme membership during which no benefits are payable for any condition (except emergency care and PMB emergency conditions). This applies to new members who join without evidence of prior continuous scheme membership.

Condition-specific waiting period: A 12-month period from the date of scheme membership during which the scheme will not pay for treatment related to a condition the member had before joining. This applies to pre-existing conditions.

Late-joiner penalty: Members who join a medical scheme for the first time after the age of 35, or who have had a break in scheme membership, may be subject to a late-joiner penalty — an additional premium loading applied permanently. This is separate from a waiting period but adds cost.

What Waiting Periods Cannot Cover

Here is the critical limit on waiting periods that most members are unaware of:

Waiting periods cannot exclude Prescribed Minimum Benefits (PMBs).

This means: even if you are in your general waiting period or condition-specific waiting period, your medical scheme must cover:

• Emergency medical conditions (life-threatening situations requiring immediate care)
• PMB-defined diagnosis-treatment pairs (the 270 defined DTPs)
• Chronic Disease List (CDL) conditions (only for the defined CDL medicines/treatment where the condition was pre-existing)

If your scheme denied a claim citing a waiting period, and the treatment falls within a PMB, that denial is unlawful.

What Counts as a "Pre-Existing Condition"?

A pre-existing condition is any health condition that existed before the date you joined the scheme — even if it was undiagnosed but symptoms were present. Medical schemes may ask for a medical questionnaire or access to medical records to identify pre-existing conditions.

Common disputes arise around conditions like:

• Hypertension (often asymptomatic but detectable before joining)
• Diabetes management
• Back and joint conditions
• Mental health history
• Cancer (if diagnosis preceded membership)

Importantly, schemes cannot refuse membership based on pre-existing conditions — they can only impose a waiting period.

How Late-Joiner Penalties Work

Members who join a scheme for the first time after age 35 (or who have had a gap in membership of more than 3 consecutive months) may be classified as "late joiners." The penalty depends on the number of years the member was not a scheme member after age 35:

• 1–4 years uninsured: 5% loading
• 5–14 years: 25% loading
• 15–24 years: 50% loading
• 25+ years: 75% loading

The loading is applied as an additional percentage on top of the standard premium. It is a permanent surcharge. Late-joiner penalties are permitted by law but must be disclosed clearly at time of joining.

How to Challenge a Waiting Period Denial

Step 1 — Determine if the denied treatment is a PMB

If it is (emergency, DTP, or CDL condition) — the waiting period cannot apply. This is your strongest ground for appeal.

Step 2 — Request written confirmation of the waiting period applied

The scheme must tell you:

• Which type of waiting period applies (general or condition-specific)
• The start and end dates of the waiting period
• Which condition the condition-specific period relates to

Step 3 — Check your prior scheme membership

If you were continuously a member of another scheme before joining, you may be entitled to a reduced or waived waiting period. Produce a certificate of continuous membership from your previous scheme (most schemes issue these on request). Submit this to your new scheme to have the waiting period reduced or removed.

Step 4 — Submit a formal appeal

Write to the scheme's principal officer or complaints department. State:

• That the denied treatment is a PMB (if applicable) — and therefore the waiting period cannot apply
• That you have been a continuous scheme member and the waiting period should be waived (include certificate of continuous membership)
• Any other factual error in the scheme's application of the waiting period

Step 5 — CMS complaint

If the scheme does not resolve the matter within 30 days:

• File a complaint at medicalschemes.com
• Email: complaints@medicalschemes.com

The CMS has authority to direct schemes to waive or reduce waiting periods that are improperly applied, and to compel payment for PMB claims denied during waiting periods.

Practical Tips

• When changing schemes, always request a certificate of continuous membership from your outgoing scheme
• Never have a gap of more than 3 months between scheme memberships if you can avoid it
• If joining a new employer's scheme, check whether the employer scheme waives waiting periods for employees who transfer from another scheme
• Document any emergency or PMB treatment received during a waiting period — these cannot be denied regardless of when they occur
