Momentum Health to Administer Bonitas from June 2026

In Short

• Momentum Health will take over administration of Bonitas Medical Fund on 1 June 2026.
• Medscheme’s 43-year administration partnership with Bonitas ends on 31 May 2026.
• The move is set to shift administrator market share, with Momentum expected to rise from 22% to 30%.

What Happened

Momentum Health will start administering the Bonitas Medical Fund from 1 June 2026. Bonitas is one of South Africa’s largest medical schemes, which are member-funded health cover plans that pay for healthcare claims.

The agreement ends Medscheme’s long-running administration contract with Bonitas on 31 May 2026. Administration is the behind-the-scenes work, like handling member onboarding, claims processing, provider payments, call centres, and compliance reporting.

Momentum expects the Bonitas deal to add more than 750,000 beneficiaries to its administration base. That would increase its medical scheme administration market share from 22% to 30%, positioning it as the second-largest administrator behind Discovery Limited.

The Bonitas shift was reported alongside Momentum Group’s interim results for the six months to December 2025. The group said normalised headline earnings rose 8% to R3.7 billion, and it declared a dividend of 110 cents per share, up 29%.

Why It Matters

This is a major supplier switch in a heavily regulated part of the healthcare industry. When a large medical scheme changes administrators, it can affect service levels, claims turnaround times, member communications, and the tech systems used by brokers and healthcare providers.

For Momentum, the deal strengthens its scale in health administration, which is a volume business where larger books can spread operating costs across more members. For Medscheme, losing a large account highlights how competitive scheme administration has become, even for incumbents.

The transition timeline also matters. With a start date in June 2026, there is a long runway for data migration, member record transfers, and integration planning, which are common failure points in large healthcare admin moves.
