Question

multiple choice question

the order of the codes must be the same as shown in the alphabetic index: the ____ comes first, followed by the ____ code.

etiology; manifestation
category; subcategory
manifestation; etiology
code; category

Explanation:

Identify the core coding convention

The question asks about the sequencing rule for dual coding in medical classification systems like ICD-10-CM. Specifically, it refers to the mandatory sequencing rule when a condition has both an underlying cause and multiple body system manifestations. This is governed by the Etiology Manifestation Convention.

Analyze the sequencing rule

Under the Etiology Manifestation Convention, ICD-10-CM requires the underlying condition (the etiology) to be sequenced first, followed by the manifestation code. In the Alphabetic Index, these are often displayed together, with the manifestation code listed second in brackets, indicating it can never be designated as the principal or first-listed diagnosis.

Match with the options

The prompt states: "the ______ comes first, followed by the ______ code."

• First blank: etiology
• Second blank: manifestation

This matches the first option: "etiology; manifestation".

Answer:

• etiology; manifestation (Correct answer)
• category; subcategory
• manifestation; etiology
• code; category
