Belgian National Institute for Health and Disability Insurance (INAMI-RIZIV) has issued an agreement document on March 17, 2020, providing principles for billing and funding the Coronavirus (COVID-19) Detection Tests. Previously in Protocol for Hospitals on March 10, 2020, it was outlined that COVID-19 tests performed outside the National Reference Center for Respiratory Pathogens at UZ Leuven have no specific nomenclature codes, and no reimbursement was provided, therefore, was paid by patients. The new agreement clarifies principles for reimbursement, but the invoicing for the tests still on hold.
