The International Statistical Classification Of Diseases And Related Health Problems, 10th revision, German Modification (ICD-10-GM) is the official classification for the encoding of diagnoses in inpatient and outpatient medical care in Germany.
The currently valid version is ICD-10-GM 2019.

ICD-10-GM is available in various versions and formats in German language and is updated annually. The currently valid version is effective from the beginning until the end of a calendar year. In the case of corrections during this period of validity you will be informed by our Newsletter DIMDI News.

Official diagnostic classification

DIMDI publishes the ICD-10-GM on behalf of the Federal Ministry of Health; it is in the public domain. Its use in inpatient care is laid down in § 301 Volume V of the German Social Security Code (SGB V) and in outpatient care is laid down in § 295 SGB V.Please edit this content section.

Structure of ICD-10-GM

The ICD-10-GM consists of two parts:

  • Tabular list: consisting of the hierarchically ordered list of codes together with supplementary information: The preface contains instructions on the encoding process and a commentary on the most important changes compared to the previous version. The appendix contains a morphology of neoplasms and some assessment procedures for the identification of functional impairments.
  • Alphabetical Index with a comprehensive compilation of encoded diagnoses from the terminology used in inpatient and outpatient medical care. Until the publication of the 2004 version of the ICD-10-GM, it was referred to as the ICD-10 Thesaurus of Diagnostic Terms.

Far wider than the instructions within ICD-10-GM is the comprehensive system of rules pertaining to ICD-10-WHO. It contains general information about the structure and use of ICD-10 as well as general rules and directives for the encoding of diseases. This basic information also applies to ICD-10-GM. However, priority is given to section-specific encoding guidelines.

ICD-10-GM as the basis for remuneration and financing systems

ICD-10-GM forms an important basis for the G-DRG and PEPP case-based fixed sum payment systems. Both are provided by InEK (Institute for the Hospital Remuneration System) on behalf of the self-governing partners of the German health care (the unified decision-making body of payer and provider corporatist constituencies) and are used in inpatient care. The reimbursement of outpatient care based on the German Uniform Assessment Standard (EBM) and the morbidity-based risk structure equalisation fund require diagnoses encoded in accordance with ICD-10-GM, as well.

Proposal procedure for ICD-10-GM and OPS

ICD-10-GM is maintained and updated in an elaborate process. At present, this is based on a proposal procedure conducted annually under the lead management of the DIMDI.

ICD-10-GM as an adaptation of ICD-10-WHO

ICD-10-GM is an adaptation of ICD-10-WHO, the World Health Organisation's "International Statistical Classification of Diseases and Related Health Problems" translated into German by the DIMDI (the number 10 refers to the 10th revision of the classification, GM means "German Modification"). It is part of the group of international health-related classifications. Until 2003, ICD-10-GM was known as ICD-10-SGB-V; SGB V stands for "Volume V of the German Social Security Code".

ICD-10-GM is a version adapted to the specific requirements of the German health care system. In structure and design, it corresponds to the VAS (Tabular List of inclusions and four-character subcategories) of the German language version of the ICD-10-WHO. From 1 January 2000, the classification has been used for the encoding of diagnoses in inpatient and outpatient health care (§§ 295 and 301 SGB V), particularly as part of the G-DRG (German Diagnosis Related Groups) payment system.
