Japan's Ministry of Health, Labor, and Welfare has approved Fujifilm Healthcare's AI algorithm for chest x-ray analysis CXR-AID for reimbursement. The algorithm is based on AI software developer Lunit's Insight CXR.
The reimbursement will be provided under the ministry's "Imaging Diagnosis Reimbursement Class 3" category, Lunit said. The clearance has prompted the Japan Radiological Society (JRS) to release a guideline that outlines AI implementation in hospitals and a list of medical AI software eligible for health insurance reimbursement, according to the firm.
![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
