multiple choice question

______ is used when two conditions could not exist together, such as an acquired and a congenital condition; it means
ot coded here.\

includes 2
includes 1
excludes 1
excludes 2

Explanation:

Identify the definition

The question asks for an ICD-10-CM coding convention/instructional note that means "not coded here" and is used when two conditions cannot exist together (such as an acquired and a congenital version of the same condition).

Analyze the options

Using the ICD-10 Instructional Notes knowledge point:

• Excludes 1: This is a pure exclusion note. It means "NOT CODED HERE!" An Excludes 1 note indicates that the code excluded should never be used at the same time as the code above the Excludes 1 note. An example of this is when two conditions cannot occur together, such as a congenital form and an acquired form of the same condition.
• Excludes 2: This means "Not included here." It indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. If documented, both codes can be billed together.
• Includes 1 / Includes 2: These are not standard ICD-10-CM instructional note terms (the standard is "Includes" notes).

Match with the correct term

The definition "not coded here" and the rule that the two conditions cannot exist together (e.g., acquired vs. congenital) perfectly matches the definition of an Excludes 1 note.

Answer:

• Includes 2
• Includes 1
• Excludes 1 (Correct answer)
• Excludes 2
