Coding notes (synonyms, inclusions, etc.) contain valuable information. Unlike other apps, this app includes and searches the coding notes (as well as all other content)!

The following details are displayed for each ICD code in the app: (see screenshots)

• ICD code and text
• ICD chapter, group, and subgroup
• Reporting requirements (physician/laboratory)
• Age/gender restrictions

• Frequency in outpatient/inpatient settings

• Reference to the German Medical Devices Catalogue: Indication groups (AT, ST1, etc.) separated by:

- Special prescription needs

- Long-term medical device needs
• Reference to morbidity-related factors Risk adjustment (disease, HMG, DXG)

• Coding instructions (includes/excludes and even definitions)

each at the group/3-digit or end-digit level

What is ICD-10?

The International Classification of Diseases, German Modification (ICD-10-GM) is the official classification for diagnoses in outpatient and inpatient care in Germany and serves to code diseases and causes of death.

The ICD-10-GM is a German-adapted version of the WHO ICD-10.

The Federal Institute for Drugs and Medical Devices (BfArM) publishes the ICD-10-GM on behalf of the Federal Ministry of Health. Its use is governed by Section 301 of the German Social Code, Book V (SGB V), and by Section 295 of the SGB V, both for inpatient and outpatient care.
