How it Works
MedCodER is an AI medical coding software that uses a combination of natural language processing (NLP) and machine learning to extract disease diagnoses, supporting evidence, and associated ICD-10 codes from medical records.
The software starts by using a Large Language Model (LLM) to extract disease diagnoses, supporting evidence text, and associated ICD-10 codes. This is done by asking the LLM to generate structured JSON output of these entities from the medical record.

The LLM is specifically GPT-4, which outperformed other commercial and open LLMs on the US medical licensing exams dataset (MedQA) in the HELM leaderboard.
To mitigate potential hallucinations, the software implements additional verification steps, such as fuzzy matching to replace extracted terms with their exact or closest match from the medical record.
The extracted diagnoses are then used in a retrieval step to generate a candidate set of ICD-10 codes through semantic search between the extracted diagnoses and the descriptions of valid ICD-10 codes.
This approach reduces the number of potential codes to a more manageable set, making it easier to select the correct ICD-10 code.
MedCodER's retrieval step uses a ranked list of ICD-10 codes directly mapped to specific diagnoses, enhancing interpretability.
Here's a summary of MedCodER's steps:
- Step 1: Disease Diagnoses, Supporting Evidence & ICD-10 Code Extraction
- Step 2: ICD-10 Retrieval Augmentation
- Step 3: Re-ranking Step (error mitigation for generated ICD-10 codes)
MedCodER outperforms state-of-the-art deep learning and generative AI based solutions for automatic ICD-10 coding, significantly enhancing ICD-10 coding performance while remaining interpretable.

Error Analysis
MedCodER's error analysis revealed some surprising limitations, but also a promising solution. Even when the extracted disease diagnosis is incorrect, the codes are often very close.
One of the main issues with MedCodER is its reliance on prompting and retrieval approaches for ICD-10 coding. However, the tool can overcome these shortcomings due to its re-ranking capability.
MedCodER's error analysis highlighted the importance of contextual analysis in medical coding. This involves analyzing physician notes, lab results, and other documentation to assign accurate codes.
For example, if a physician documents a patient's diagnosis and treatment, a basic tool might only detect specific keywords and apply generic codes. However, an advanced AI tool with contextual analysis can recognize the interplay between conditions and apply the correct combination codes.

Medical coding involves identifying disease entities from medical records, which is a form of Named Entity Recognition (NER) in biomedical NLP. Domain-specific models like BioBERT have achieved high F1 scores on benchmark datasets, but recent advancements like UniNER and GLiNER have shown competitive zero-shot performance on the NCBI Disease corpus.
A robust AI tool should analyze physician notes, lab results, and other documentation to assign accurate codes, rather than relying solely on keyword spotting. For instance, an AI tool with contextual analysis capabilities would recognize the interplay between diabetes and hypertension and apply the correct combination codes.
To evaluate the efficacy of retrieval and re-ranking on ICD coding performance, an ablation study was conducted. The results show that re-ranking the combined set of prompted and retrieved ICD-10 codes outperforms using either method alone.
Here's a breakdown of the variations of MedCodER used in the study:
The results of the ablation study demonstrate the importance of re-ranking in ICD coding performance.
