According to ICD-10-CM guidelines, what is the default code selection for hemiparesis affecting the right side of the body?

1. Dominant

2. Non-Dominant

3. Both Dominant and non-dominant

4. You are unable to code it

The correct answer is: Dominant

The default code selection for hemiparesis affecting the right side of the body is classified as "dominant." This is because, in most individuals, the left hemisphere of the brain controls the right side of the body, and the left hemisphere is typically where the dominant language and motor function centers reside. Therefore, when coding for hemiparesis that affects the right side, it is accurate to assign it to the dominant side. In contrast, codes for hemiparesis affecting the left side of the body would typically be considered non-dominant, as the right hemisphere, which controls the left side, is usually not the dominant part of the brain for language in most individuals. The guidelines specify this default coding to ensure consistency and accuracy in charting and reporting, which is crucial for proper reimbursement and medical record-keeping. The other options do not apply in this case. Selecting both dominant and non-dominant would create ambiguity in the coding process, and indicating that it cannot be coded lacks clarity. Therefore, understanding that hemiparesis affecting the right side of the body defaults to being classified as dominant is essential for accurate coding practices.
