In a significant move, Discovery Health Medical Scheme (DHMS) has announced it will absorb the full financial impact of a major administrative error that saw thousands of its members overpay for medication claims throughout 2025. The glitch, attributed to a system-wide processing fault, incorrectly calculated members’ co-payments and out-of-pocket expenses for prescription medication at network pharmacies.
The scheme confirmed that approximately 16,500 principal members—affecting an even larger number of dependants—will receive refunds for overpayments made between 1 January 2025 and 31 December 2025. The total amount to be repaid runs into several million rands, with individual refunds varying based on each member’s claim history.
The Glitch: How Members Were Overcharged
According to a statement from Dr. Ryan Noach, CEO of Discovery Health, the error stemmed from a “technical failure in the claims adjudication engine.” The system failed to correctly apply the scheme’s rules and benefits for certain chronic and acute medications purchased at retail pharmacies. Instead of charging members the accurate, lower co-payment as stipulated in their plans, the system defaulted to a higher, incorrect tariff.
“In essence, for a subset of medication claims, members were charged an out-of-pocket amount that was not in line with their plan benefits. This was our error, and we take full responsibility,” Dr. Noach stated.
The issue was identified through internal auditing processes and a noticeable increase in member queries to the client service centre regarding higher-than-expected pharmacy bills.
The Resolution: Full Refunds and System Fix
Discovery Health has pledged a full, automatic refund process. Affected members do not need to apply or submit any paperwork.
- The scheme will calculate each member’s total overpayment for the 2025 period.
- Refunds will be processed via Electronic Funds Transfer (EFT) directly into the bank account linked to the member’s Discovery profile.
- Members are expected to begin receiving communications from the scheme starting next week, detailing the exact refund amount and the timeline for payment, which is slated for completion by the end of March 2026.
- The underlying system fault has been identified and permanently resolved, according to the scheme’s technical teams.
Leadership Accountability and Regulatory Scrutiny
“This proactive repayment initiative is the right and ethical course of action. Our members trust us to manage their healthcare funding accurately, and we have fallen short of that standard in this instance. We sincerely apologise for the distress and inconvenience this has caused,” Dr. Noach said.
The Council for Medical Schemes (CMS) has been notified of the error and the refund plan. The CMS is expected to monitor the repayment process closely. Industry analysts suggest this move by Discovery, South Africa’s largest open medical scheme, is likely aimed at mitigating regulatory penalties and maintaining member trust in a highly competitive environment.
What Members Should Do
Discovery advises all members to:
- Ensure their banking details are up to date on the Discovery website or app.
- Be on the lookout for official communication (via SMS, email, or the Discovery portal) regarding their specific refund.
- Contact the Discovery Client Service Centre only if they have not received communication by the end of February 2026, suspect they were affected, but have changed their bank details recently.
The scheme has set up a dedicated FAQ section on its website to address member concerns about the refund process. This incident highlights the critical importance of robust systems in healthcare financing and the potential financial impact of administrative errors on consumers.
