| Challenge: | Existing benchmarks assess only the final answer with a wide numerical tolerance, overlooking systematic reasoning failures and potentially causing serious clinical misjudgments. |
| Approach: | They propose a new step-by-step evaluation pipeline that assesses formula selection, entity extraction, and arithmetic computation. |
| Outcome: | The proposed method improves the accuracy of large language models on medical benchmarks from 16.35% to 53.19%. |

| Challenge: | Clinical procedure coding is an extreme multi-label classification problem . CPTCoder predicts standardized medical procedure codes from clinical text . |
| Approach: | a new human-in-the-loop system predicts standardized medical procedure codes from clinical text. |
| Outcome: | CPTCoder outperforms baseline system by 12 and 5 points in a clinical procedure classification problem. |
