Icd-10 encryption

• On a large number of medical documents, the diagnoses of a patient mentioned herein must be transmitted in encrypted form to the respective health insurance companies since 01.01.2000. The encryption must be carried out according to § 295 and § 301 of the fifth book of the German Social Security Code (Sozialgesetzbuch) in accordance with the current version of the International Statistical Classification of Diseases and Related Health Problems (ICD-10-SGB V). For this reason, the diagnosis keywords of this encyclopedia have been assigned the corresponding ICD-10 digits.
• The official, German-language edition of the ICD-10-SGB V (10th Revision Volumes I to III) from the German Institute for Medical Documentation and Information was used for the coding. Only the first 4 digits may be transmitted to the health insurance companies (e.g. L30.9), whereby the dot between the first 3 characters and the 4th character is not regarded as a digit. In the original version of the ICD-10-SGB V, some diagnoses only consist of three ICD-10 digits (e.g. A46.). The 4th digit was filled with an "x", following the WHO proposal. Some of the frequent and important dermatological-allergological diagnoses are unfortunately not sufficiently classified in the ICD-10-SGB V. The official catalogue often does not do justice to the comprehensive, interdisciplinary complexity of dermatology and its different diagnoses. These deficits have been compensated in an exemplary manner by the efforts of the working group "Dermatologischer Diagnosenkatalog" (DDK) e.V. (Dermatological Diagnostic Catalogue) under the patronage of the German Dermatological Society. The DDK has established a dermatological diagnosis catalogue from which the subject-specific, differentiated dermatological diagnoses can be taken.
• In the review of this encyclopedia the repetition of some ICD-10 digits has to be noted. On the one hand it is caused by the parallel coding of synonyms of dermatological diagnoses, on the other hand repetition figures result from the assignment of the same ICD-10 figures to different dermatological diagnoses. For verification when applying the ICD-10 digits for a defined diagnosis, it is recommended to first search for the diagnosis super-group in the alphabetical part (volume III) of the official edition of the ICD-10-SGB V in order to then find the appropriate diagnosis sub-group in the systematic part (volume I). In the coding of tumor diagnoses, the 4th digit was replaced in most cases by a variable in the form of the letter "M" or "L" so that the same tumor diagnosis of different anatomical localization does not have to be listed individually. The coding of the letters "M? or "L? can be taken from the localization key mentioned below. Please note the different meaning of the number "8" as the 4th digit in the L-key. For the chapters D03 and D04, the digit "8" as 4th digit has a different meaning than for the chapters C43 and C44 (regulation of the ICD-10-SGB V).

Notice! In the Federal Republic of Germany, the ICD-10-GM (GM = German Modification) is currently the binding coding basis.
