Question

Quizplus · Accepted Answer

A valid principal diagnosis code must represent the main reason for the patient's encounter and is typically related to a disease or illness. Option A is a valid code, but it represents the outcome of delivery, not a disease or illness. Option C represents an external cause of injury or poisoning and is not a valid principal diagnosis code. Option D is a code for a specific type of tumor, not a principal diagnosis code. Option B is a valid code for a single live birth in a hospital, which could be the reason for a patient's encounter.
