Other secondary hypertension

This code signifies elevated blood pressure that is a direct consequence of an underlying, identifiable medical condition, excluding those specified as renovascular, endocrine, or other specific types of secondary hypertension. It indicates that the hypertension is not primary (essential) but rather a symptom or complication of another disease process.

Use this code when documentation clearly links hypertension to a secondary cause not otherwise classified, such as hypertension due to neurological disorders, acute stress, or certain medications. The physician's notes should explicitly state the secondary nature of the hypertension and the specific underlying condition.

• Always code the underlying condition first, followed by this code to indicate the secondary hypertension.
• Distinguish carefully from essential hypertension (I10) and other specified secondary hypertensions (e.g., I15.0, I15.1, I15.2).
• Ensure the medical record clearly identifies the specific "other" secondary cause; avoid using this code without a documented etiology.
