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.
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.
The ICD-10-GM consists of two parts:
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 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.
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.
