Clinical ModernBERT for ICD Coding

Automated ICD-9/10 code prediction from clinical discharge summaries using Clinical ModernBERT with label-wise attention mechanism. This model is designed for multi-label classification of the 200 most frequent ICD codes from long clinical notes (up to 4096 tokens).

Model Details

Property	Value
Base Model	Simonlee711/Clinical_ModernBERT
Architecture	Label-wise Attention + Multi-label Classifier
Number of Labels	200 (most common ICD-9/10 codes)
Max Context Length	4096 tokens
Dataset	MIMIC-III Clinical Notes
Task	Multi-label Text Classification
Language	English (Clinical)

Dataset Split

Split	Samples
Train	78,264
Validation	19,566
Test	24,458

Performance

Metric	Value
Micro F1	0.437
Macro F1	0.412
Precision	0.304
Recall	0.780
Recall@20	0.758

The high recall (0.780) makes this model suitable for clinical decision support where missing a code is more costly than over-predicting.

Usage

⚠️ Important: Before using AutoModel.from_pretrained(), you must download and import model.py to register the custom architecture with transformers.

Step 1: Download and import model.py

python

import sys
from huggingface_hub import hf_hub_download
import importlib.util

# Download model.py from the repository
path = hf_hub_download(repo_id="nikhil061307/clinical-modernbert-icd-200", filename="model.py")

# Load it as a module
spec = importlib.util.spec_from_file_location("custom_model", path)
custom_model = importlib.util.module_from_spec(spec)
sys.modules["custom_model"] = custom_model  # Register to avoid transformers internal errors
spec.loader.exec_module(custom_model)

Step 2: Use with AutoModel

python

import pickle
from transformers import AutoModel, AutoTokenizer

model = AutoModel.from_pretrained("nikhil061307/clinical-modernbert-icd-200")
tokenizer = AutoTokenizer.from_pretrained("Simonlee711/Clinical_ModernBERT")

# Download ICD codes mapping
codes_path = hf_hub_download(repo_id="nikhil061307/clinical-modernbert-icd-200", filename="top_codes.pkl")
with open(codes_path, "rb") as f:
    icd_codes = pickle.load(f)

# Inference
text = "Patient with chest pain and shortness of breath"
enc = tokenizer(text, return_tensors="pt", truncation=True, max_length=512)
out = model(**enc)

probs = torch.sigmoid(out["logits"]).squeeze()
top_k = torch.topk(probs, 5)
print("Top 5 predictions:")
for idx, prob in zip(top_k.indices, top_k.values):
    print(f"  ICD code {icd_codes[idx.item()]}: {prob.item():.4f}")

Complete Example

python

import sys
import pickle
import torch
from huggingface_hub import hf_hub_download
import importlib.util

# Step 1: Download and register custom model
path = hf_hub_download(repo_id="nikhil061307/clinical-modernbert-icd-200", filename="model.py")
spec = importlib.util.spec_from_file_location("custom_model", path)
custom_model = importlib.util.module_from_spec(spec)
sys.modules["custom_model"] = custom_model
spec.loader.exec_module(custom_model)

# Step 2: Load with AutoModel
from transformers import AutoModel, AutoTokenizer

model = AutoModel.from_pretrained("nikhil061307/clinical-modernbert-icd-200")
tokenizer = AutoTokenizer.from_pretrained("Simonlee711/Clinical_ModernBERT")

# Step 3: Download ICD codes mapping
codes_path = hf_hub_download(repo_id="nikhil061307/clinical-modernbert-icd-200", filename="top_codes.pkl")
with open(codes_path, "rb") as f:
    icd_codes = pickle.load(f)

# Step 4: Predict
text = "Patient with chest pain and shortness of breath"
enc = tokenizer(text, return_tensors="pt", truncation=True, max_length=512)
out = model(**enc)

probs = torch.sigmoid(out["logits"]).squeeze()
top_k = torch.topk(probs, 5)
print("Top 5 predictions:")
for idx, prob in zip(top_k.indices, top_k.values):
    print(f"  ICD code {icd_codes[idx.item()]}: {prob.item():.4f}")

The label-wise attention mechanism allows each ICD code to attend to the most relevant parts of the clinical note, improving multi-label performance on long documents.

Limitations & Intended Use

Intended Use: Research, clinical decision support assistance, and NLP benchmarking
Not Intended For: Autonomous clinical coding without human oversight
Data Source: Trained on MIMIC-III (de-identified US ICU data). Performance may vary on notes from different institutions, EHR systems, or non-ICU settings
Bias: May reflect coding patterns specific to MIMIC-III's patient population and clinical conventions

Requirements

pip install torch transformers
