Radiologists say the proposed Medicare rebates for the upcoming National Lung Cancer Screening Program, which will be mandatory to bulk-bill, are around $100 too low.

The program starting in July 2025 will involve GPs identifying eligible patients based on smoking history and referring them for low-dose chest CT.

The government is suggesting that these CT scans attract a rebate equal to an existing bulk-billed chest CT item: $308.

However, the Australian Diagnostic Imaging Association says that CT scan rebates for the screening program should top $400.
