What 8.4 million claims reveal about how healthcare really works in Nigeria
An analysis of anonymised Medismarts data shows how decisions, payments, and care delivery are becoming more structured across Nigeria’s health system
Most conversations about healthcare in Nigeria focus on what people can see — hospitals, doctors, equipment, and access. But another part of the system plays an equally important role, even though it is less visible.
Every hospital visit triggers a series of decisions behind the scenes. Eligibility has to be confirmed. Treatments must be approved. Claims are submitted, reviewed, and eventually paid. For years, many of these steps have depended on manual processes, which often lead to delays, inconsistencies, and limited visibility into how the system functions.
Using anonymised data from over 8.4 million claims processed across its platform, Medismarts provides a clearer view of what is happening within Nigeria’s healthcare system. The data shows not just how care is delivered, but how it is financed, approved, and sustained.
Between 2024 and 2025, total claims processed increased from 6.32 million to 8.43 million, a 33.3% rise in activity within one year. At the same time, the average time to process claims dropped from 80.9 days to 56.3 days. This means that even as more people used the system, the system became faster.
That combination points to something important. It suggests that improvements are not just happening at the surface level but also within the structure of how healthcare decisions are made.
What the data reveals about care, cost, and coordination
When healthcare data is viewed at scale, patterns emerge.
Malaria remains the most common diagnosis, accounting for over 60% of recorded cases. Upper respiratory infections follow, while hypertension continues to appear as a growing concern. Among children between 0 and 5 years old, malaria alone accounts for more than 400,000 cases in a single year.
