Question

When two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition, what note is used in ICD-10-CM

Answer 1

In ICD-10-CM, a note is used to distinguish between conditions that cannot occur together by indicating the use of additional codes for further specification.

Step-by-step explanation:

In ICD-10-CM, when two conditions cannot occur together, a note is used to distinguish between them. Specifically, the note 'Use additional code' is used to indicate that additional codes should be used to further specify the condition. This helps to differentiate between conditions that may have similar characteristics but are distinct from each other.
