Health Insurance Reimbursement Data

Nationwide

Number of anti-VHD antibody tests reimbursed in the public and private sectors

In 2024, more than 36,000 anti-VHD antibody (Ab) tests (procedure code 1740 in the Nomenclature of Medical Laboratory Procedures) were performed and reimbursed across all health insurance plans.

Between 2014 and 2019, the number of anti-VHD Ab tests increased annually by between 6% and 17%, then decreased in 2020 (-5%) due to the COVID-19 pandemic. Starting in 2021, the annual increase was more significant (20% between 2020 and 2021, 15% between 2021 and 2022, and 17% between 2022 and 2023), likely due to recent therapeutic advances (European marketing authorization for Bulevirtide in the third quarter of 2020). This increase is less pronounced between 2023 and 2024 (+7%).

Between 2014 and 2019, the annual number of reimbursed tests increased more sharply in the private sector (+87%) than in the public sector. This trend has reversed since 2020, with a larger increase in the public sector (+96%) than in the private sector (+62%). Note: Screening tests performed during hospitalization in a public facility are not included in the public sector data.
