What ICD-9-CM code corresponds to benign hypertension in a patient being evaluated for cataract surgery?

1. 401.1

2. 290.0

3. 378.1

4. 790.5

The correct answer is: 401.1

The code that corresponds to benign hypertension is 401.1. Benign hypertension is considered a less severe form of hypertension, as opposed to malignant hypertension, which requires more aggressive treatment and intervention. In the context of a patient undergoing evaluation for cataract surgery, it's important to document any pre-existing conditions, including benign hypertension, to ensure proper perioperative management and risk assessment. The other codes do not appropriately represent benign hypertension. For instance, 290.0 would imply a diagnosis related to dementia, which is not relevant in the case of cataracts. Similarly, 378.1 refers to other specified disorders of the eye muscle, which again does not align with hypertension, and 790.5 indicates abnormal blood pressure readings, not specifically benign hypertension. Therefore, 401.1 is the most accurate and specific code in this scenario.
