Question

multiple choice question

the use of ______ in the alphabetic index around a code means that it cannot be the first-listed code in coding the diagnostic statement.

italics
brackets
bolded text
parentheses

Explanation:

Identify the convention for sequencing codes

Using the ICD-10 Conventions and Alphabetic Index knowledge points:
In ICD-10-CM coding, punctuation marks and formatting styles serve as critical instructional conventions. When a code appears in the Alphabetic Index, specific formatting indicates sequencing rules.

Analyze the meaning of brackets

Using the ICD-10 Conventions knowledge point:

• Brackets \([ ]\) are used in the Alphabetic Index to identify manifestation codes.
• A code enclosed in brackets in the Alphabetic Index represents a manifestation of an underlying disease.
• According to the etiology/manifestation convention, the underlying disease code must be sequenced first, followed immediately by the manifestation code.
• Therefore, a code enclosed in brackets can never be designated as the principal or first-listed diagnosis.

Evaluate other options

Using the ICD-10 Conventions knowledge point:

• Italics are used in the Tabular List to identify manifestation codes, but the question specifically asks about the punctuation mark used around a code in the Alphabetic Index.
• Parentheses \(( )\) enclose nonessential modifiers, which do not affect the code selection or sequencing.
• Bolded text is used for main terms and codes in the Tabular List but does not restrict sequencing.
• Thus, brackets is the correct term.

Answer:

• italics
• brackets (Correct answer)
• bolded text
• parentheses
