CPT / HCPCS Procedure Coder

Part of the [AxisMapper Medical AI Suite](https://huggingface.co/collections/AmareshHebbar/axiomapper-medical-ai-suite) — 16 domain-specific SFT datasets for fine-tuning medical LLMs.

Built by [AmareshHebbar](https://huggingface.co/AmareshHebbar) | Studio Ilios / Humanova Minds

What this dataset does

Procedure descriptions → correct CPT/HCPCS code with RVU data

Why download this

Build procedure coding assistants, verify CPT code assignments, or automate outpatient charge capture. Covers all specialties in the CMS PFS.

Dataset stats

Data format

Every row is a messages list in chat format — compatible with Unsloth, TRL SFTTrainer, LLaMA-Factory, and any OpenAI-style fine-tuning pipeline:

{
  "messages": [
    {"role": "system",    "content": "You are a ..."},
    {"role": "user",      "content": "Procedure: Percutaneous coronary intervention with drug-eluting stent, single vessel."},
    {"role": "assistant", "content": "CPT/HCPCS: 92928
Description: PCI with drug-eluting stent, single major coronary artery
Work RVU: 14.27
Source: CMS PFS 2026"}
  ]
}

Data source

CMS Physician Fee Schedule 2026 — PPRRVU nonQPP (17k procedures) → https://www.cms.gov/medicare/payment/fee-schedules/physician

All data is extracted from authoritative public sources. No LLM-generated or synthetic content.

Who should use this

Medical coders, outpatient billing teams, health IT developers, coding audit firms.

Quick start

from datasets import load_dataset

ds = load_dataset("AmareshHebbar/cpt-coder-sft")
print(ds["train"][0])

Fine-tuning example (Unsloth)

from unsloth import FastLanguageModel
from trl import SFTTrainer
from datasets import load_dataset

model, tokenizer = FastLanguageModel.from_pretrained(
    model_name="unsloth/Qwen2.5-3B-Instruct",
    max_seq_length=2048,
    load_in_4bit=True,
)

dataset = load_dataset("AmareshHebbar/cpt-coder-sft", split="train")

trainer = SFTTrainer(
    model=model,
    tokenizer=tokenizer,
    train_dataset=dataset,
    dataset_text_field="messages",
    max_seq_length=2048,
)
trainer.train()
