Iowa mandates coverage for biomarker cancer tests, lifts prior authorization for in-network services
A new Iowa law, effective July 1, 2026, requires all state-regulated health plans to cover biomarker testing for cancer diagnosis and treatment. The law specifically prohibits prior authorization for biomarker tests when the ordering provider is in-network and the lab is in-network. For out-of-network labs, prior authorization is still permissible. This operational change requires oncology practices to verify patient plan type and network status before ordering these tests to avoid delays and denials. Update your internal lab-ordering protocols for Iowa patients to comply by the July 1 effective date.
