Code	Description	When to Use	Key Documentation
I15.0	Renovascular hypertension	Use when hypertension is due to renal artery stenosis.	Renal artery stenosis >70% on angiography BP >140/90 with abdominal bruit
I15.1	Hypertension secondary to other renal disorders	Use when hypertension is due to a specific renal disorder other than stenosis.	Documented renal disorder causing hypertension
I15.2	Hypertension secondary to endocrine disorders	Use when hypertension is due to an endocrine disorder.	Elevated aldosterone/renin ratio Hypokalemia

Documentation & Coding Risks

Avoid these common issues when documenting Secondary Hypertension.

Failing to specify the underlying cause of hypertension.

Impact

Clinical: May lead to inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims or reduced reimbursement.

Mitigation

Ensure thorough documentation of the patient's condition., Use specific ICD-10 codes that reflect the underlying cause.

Coding secondary hypertension as essential hypertension

Impact

Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data affecting patient care and research.

Mitigation

Ensure documentation specifies the underlying cause of hypertension.

Incorrect coding of hypertension

Impact

Risk of coding secondary hypertension as primary due to lack of documentation.

Mitigation

Ensure all documentation specifies the underlying cause of hypertension.
