ICD 10 codes are important for several reasons:

- A letter that indicates the chapter of the classification (e.g., A for certain infectious and parasitic diseases, B for neoplasms, C for diseases of the blood and blood-forming organs, etc.)
- Two digits that indicate the category of the diagnosis (e.g., A00 for cholera, B20 for HIV disease resulting in infectious and parasitic diseases, C81 for Hodgkin lymphoma, etc.)
- A decimal point followed by one or more digits that indicate the subcategory or specificity of the diagnosis (e.g., A00.0 for cholera due to Vibrio cholerae 01, biovar cholerae, B20.1 for HIV disease resulting in tuberculosis, C81.0 for nodular lymphocyte predominant Hodgkin lymphoma, etc.)
- Optionally, an extension character that indicates additional information such as laterality, severity, or episode of care (e.g., A00.0A for cholera due to Vibrio cholerae 01, biovar cholerae with dehydration, initial encounter; B20.11 for HIV disease resulting in pulmonary tuberculosis with multidrug-resistant tuberculosis; C81.00 for nodular lymphocyte predominant Hodgkin lymphoma unspecified site)
