Question 16

When a code assignment specifically identifies a chromosomal abnormality, manifestations that are an inherent component should be coded separately.

Accepted Answer

When a code assignment specifically identifies a chromosomal abnormality, manifestations that are an inherent component of the abnormality should not be coded separately, as they are considered to be included within the code for the chromosomal abnormality.

Question 17

Which of the following conditions would not be reported with code Q65.8?

Accepted Answer

Congenital dislocation of the right hip is reported with a specific code, Q65.2, not with the general code Q65.8, which is for other congenital deformities of the hip.
