ICD-10 Coding

The AAAAI is your source for ICD-10 information and resources. The ICD-10 system is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD), a medical classification list by the World Health Organization. It expanded the 14,000 diagnoses codes, available in ICD-9, to more than 60,000 available in ICD-10.

Review the diagnoses codes available here for the practicing allergist / immunologist, and check back often. New coding questions and answers will be posted soon.
