  1. ICD-10 M31.1 “Thrombotic Microangiopathy”, ICD-10 D59.3 “Hemolytic Uremic Syndrome”, PD Primary Diagnosis, SD Secondary Diagnosis (SD), M Munich = Medical Clinic and Policlinic IV of the Ludwig-Maximilians-University Munich; HER = Herne = Marien Hospital Herne; HL = Lubeck = University Hospital Schleswig-Holstein, Lubeck; BN = Bonn = University Hospital Bonn; F = Frankfurt am Main = University Hospital Frankfurt; KI = Kiel = University Hospital Schleswig-Holstein, Kiel; GP = Göppingen = Alb Fils Kliniken GmbH; H = Hannover = Clinic for Kidney and Hypertension Disorders; *In Hannover, one aTTP patient was coded as D59.3 PD and one as D59.3 SD; this was identified as miscoded by the study physician; In order to adequately consider these patients, one patient each was classified as M31.1 PD and M31.1 SD and thus assigned to the correct ICD-10 coding
