Final answer:
The statement is false; an 'Excludes1' note indicates mutually exclusive codes, whereas an 'Excludes2' note allows coding both conditions together if the patient has them simultaneously.
Step-by-step explanation:
The statement that 'Excludes1 note is more optional while Excludes2 note is mandatory' is false. In the context of medical coding, particularly with the International Classification of Diseases (ICD), an 'Excludes1' note indicates that the codes should never be used together because they are mutually exclusive. On the other hand, an 'Excludes2' note indicates that the conditions excluded are not part of the condition it is excluded from but a patient may have both conditions at the same time, and it is permissible to code them together if the patient does indeed have both conditions.
