The paper researches the problem of concept and patient representations in the medical domain. We present the patient histories from Electronic Health Records (EHRs) as temporal sequences of ICD concepts for which embeddings are learned in an unsupervised setup with a transformer-based neural network model. The model training was performed on the collection of one million patients' histories in 6 years. The predictive power of such a model is assessed in comparison with several baseline methods. A series of experiments on the MIMIC-III data show the advantage of the presented model compared to a similar system. Further, we analyze the obtained embedding space with regards to concept relations and show how knowledge from the medical domain can be successfully transferred to the practical task of insurance scoring in the form of patient embeddings.
