Final answer:
In ICD-10, the 'Excludes' note is used to indicate that an entry is not part of the preceding code, with 'Excludes1' and 'Excludes2' designating specifics of non-inclusion.
Step-by-step explanation:
The convention used in ICD-10 to indicate that an entry is not classified as part of the preceding code is C) Excludes. This convention is critical for ensuring diagnostic codes are used correctly. The ICD-10 uses two types of excludes notes: 'Excludes1' and 'Excludes2'. 'Excludes1' indicates that the condition excluded is not part of the condition represented by the code, and cannot be used at the same time. 'Excludes2' indicates that the conditions excluded are not part of the condition it is excluded from, but a patient could potentially have both conditions at the same time, therefore it would be acceptable to use both codes concurrently if this is the case.
