Medical Coding Practice Test

When both the etiology (cause) and manifestation (symptom or related condition) of a disease are listed following a sub-entry term in the Alphabetic index of ICD-9-CM, it indicates that both codes should be assigned in the same sequence as listed. This is because in this context, the etiology and manifestation are closely linked and should be coded together to provide a complete picture of the disease process. This approach ensures accurate reporting and addresses all aspects of the patient's condition.

The other options are not correct:

A. Assigning the codes in reverse sequence is not appropriate when both the etiology and manifestation are listed together.

B. Combining the codes into a single code could lead to loss of specific information regarding the etiology and manifestation of the disease.

D. Using only the italicized code is not sufficient in this case because both the etiology and manifestation codes are provided for a reason, and both should be reported.
