    The study evaluates the ability of GPT models to extract OPS codes from surgical reports of meningioma resections.

  • 2

    Surgeons and professional coders achieved sufficient coding accuracy of 99-100%, while LLMs like GPT-4o scored 78-89%.

  • 3

    For optimal coding, professional coders performed best at 94%, while surgeons had a 69% error rate.

  • 4

    GPT CodeMedic outperformed GPT-4o in both sufficient and optimal coding categories.

  • 5

    Professional coders significantly surpassed LLMs in coding accuracy, highlighting the importance of human expertise.
