Hypertension secondary to endocrine disorders

This code represents high blood pressure that is directly caused by an underlying endocrine system dysfunction. This includes conditions where hormone imbalances, such as those originating from the adrenal glands, thyroid, or pituitary, lead to sustained elevated blood pressure.

Use this code when documentation clearly links hypertension to a specific endocrine disorder, such as hyperthyroidism, Cushing's syndrome, pheochromocytoma, or primary hyperaldosteronism. The physician's diagnostic statement should explicitly state the secondary nature of the hypertension due to the endocrine condition.

• Always code the underlying endocrine disorder first, followed by this code, to accurately reflect the etiology.
• Do not use this code for essential (primary) hypertension or hypertension due to non-endocrine causes.
• Ensure the medical record explicitly states the causal relationship between the endocrine disorder and the hypertension.
