Instead of fine-tuning the model - a MedFound-Llama3-8B variant - they extracted hidden states from five transformer layers and trained lightweight linear probes on top. The combined probe, drawing on both discharge notes and serialized structured variables, hit 87.69% strict accuracy and 91.45% medical accuracy, beating single-modality probes and both an XGBoost baseline and a purpose-built clinical coding model called PLM-ICD. A 2-million-parameter adapter then transferred that capability to the older MIMIC-III dataset using only 5% of target labels.\n\nThe practical upside here is efficiency: clinical AI teams spend enormous resources fine-tuning models for every new data format or hospital system. If frozen embeddings can already separate diagnostic categories linearly - and the paper shows they get better at it in deeper layers - that cuts the adaptation cost substantially. The cross-dataset transfer result is the most useful finding, because real-world EHR systems are notoriously heterogeneous.\n\nAutomatic ICD coding has been a target for machine learning for over a decade with incremental gains; this paper's contribution is less about raw accuracy and more about showing that a shared representation space might replace a patchwork of task-specific models - a meaningful efficiency claim, if it holds outside controlled academic datasets.","[\"ai\",\"clinical-nlp\",\"ehr\",\"icd-coding\"]","2026-06-30T04:00:00.000Z","2026-06-30T05:23:37.736Z","2026-06-30T05:23:49.377Z","published",null,[],"https:\u002F\u002Fcdn.xyz.onl\u002Farticle-images\u002Ffrozen-medical-llms-can-predict-diagnoses-across-ehr-modalities.webp","ai",[25,27,28,29],"clinical-nlp","ehr","icd-coding",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.28798",0,{"sections":36},[37,41,46,51,56,61,66,71,76,81,86,90,95,100],{"name":38,"slug":25,"count":39,"latest_published_at":40},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":87,"slug":88,"count":84,"latest_published_at":89},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
