ICD10GM

ICD-10-GM is the German modification of the International Classification of Diseases, 10th Revision (ICD-10). It serves as the official diagnosis coding system in Germany for clinical documentation, health statistics, billing, and research. The modification adds country-specific codes and revisions to reflect German clinical practice, terminology, and administrative needs, while remaining compatible with the ICD-10 framework to support national reporting and reimbursement workflows, including the German diagnosis-related groups (G-DRG) system.

Versions of ICD-10-GM are released regularly to incorporate new medical knowledge and coding refinements. They are maintained and distributed by the German Institute for Medical Documentation and Information (DIMDI) and are used by hospitals, clinics, physicians, epidemiologists, and health authorities across Germany. In daily use, ICD-10-GM codes are typically used together with the German Procedure Classification (OPS) to code procedures, with the combination supporting national health statistics and DRG-based payments.

ICD-10-GM is aligned with ICD-10 but is not identical to ICD-10-CM used in the United States. The German modification includes terms and code changes tailored to the German health system, enabling standardized morbidity coding while preserving international comparability where possible. It forms the basis for epidemiological research, quality measurement, and health system planning in Germany.
