MedCode: leaderboard
Imported by benchmarklist.com from the Vals AI MedCode run: a model reads a de-identified hospital record with its discharge summary and notes, then assigns ICD-10-CM primary and secondary diagnosis codes. Two certified coders produced the reference codes that the model's output is scored against. Percentage correct, higher is better. Source: vals.ai/benchmarks/medcode.
