Question

Quizplus · Accepted Answer

Diagnosis code Z79.4 is used to describe a patient who routinely takes insulin, regardless of the duration of use. It does not specify a minimum duration of use, so choices B and C are incorrect. Choice D is incorrect because it specifies "any patient," when the code only applies to patients who regularly use insulin.
