Belgium's National Institute for Health and Disability Insurance (INAMI) identified €15.8 million in erroneous charges billed to the health insurance system in 2025. The figure was confirmed in the institute's annual report on its control activities.
The number of finalized control actions, however, fell to 334 in 2025, a significant decrease from the 483 actions closed in 2024. INAMI has attributed this decline to the increasing complexity of audits, which require more time and resources to complete thoroughly.
Despite the lower number of closures, the financial impact of the controls remained substantial. The recovered funds are reintegrated into the health insurance system, helping to ensure its financial sustainability. The institute continues to focus on combating fraud and incorrect billing practices among healthcare providers.
