Brackets used in the Alphabetic Index are used to identify ___.

Answer 20

manifestation codes

Question 21

True

Answer 25

“Unspecified” codes Use “other” code if “unspecified” does not exist.

Question 26

When can you use in Excludes1 note at the same time as the code above the Excludes1 note?

Answer 26

When the condition coded and the condition in the Excludes1 note are unrelated to each other. (This should be the only way that they exist at the same. Check w/ physician)

Answer 30

True

Question 31

When are sequela not coded before the nature or condition of the sequela?

Answer 31

When the sequela code is followed by the manifestation code in the tabular list, and title, or the code has been expanded to more characters to include manifestations.

Answer 32

A code should be assigned for both sides

If a bilateral condition is being treated on one side, and the condition that still exists on the opposite side, how should the condition be coded?

Answer 33

The bilateral code should be assigned

Question 34

If a patient is being treated for bilateral condition on one side, and the other side has previously been treated and no longer exists, how should the condition be coded?

Answer 34

Assigned the appropriate unilateral code for the side, where the condition still exists

Question 35
