Final answer:
The correct answer is B. history of hypertension.
Step-by-step explanation:
The correct answer is B. history of hypertension.
A "history of" code is assigned when a patient has a past medical condition or illness that is no longer present but may have an impact on their current or future health. In this case, a history of hypertension indicates that the patient had high blood pressure at some point in the past, but it does not necessarily mean that they currently have it. Assigning a history of code helps healthcare providers have a complete picture of the patient's medical history and make informed decisions about their care.
