-
Section Includes Notes:
Includes
Includes notes further define, or give examples of, conditions included in the section. - Diseases generally recognized as communicable or transmissible

-
Section Type-1 Excludes:
Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here." - Certain localized infections - see body system-related chapters
