| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I10 | Essential (primary) hypertension | Use when hypertension is diagnosed without heart or kidney involvement. |
|
| I11 | Hypertensive heart disease | Use when hypertension is documented with heart disease. |
|
| I12 | Hypertensive chronic kidney disease | Use when hypertension is documented with chronic kidney disease. |

Decision Criteria
clinical Criteria
- Diagnosis of hypertension without secondary causes
Applicable To
- High blood pressure
- Primary hypertension
Clinical Validation Requirements
- Blood pressure readings consistently over 130/80 mmHg on two separate visits
Code-Specific Risks
- Misclassification if secondary causes are present
Coding Notes
- Ensure no secondary causes are present before using I10.
I11 - Hypertensive heart disease
Use when hypertension is documented with heart disease.
Applicable To
- Hypertension with heart failure
Excludes
- Heart failure without hypertension (I50.-)
Clinical Validation Requirements
- Echocardiogram showing heart failure
- BNP > 400 pg/mL
Coding Notes
Document the type of heart failure and its relation to hypertension.
I12 - Hypertensive chronic kidney disease
Use when hypertension is documented with chronic kidney disease.
Applicable To
- Hypertension with CKD
Excludes
- CKD without hypertension (N18.-)
Clinical Validation Requirements
- eGFR <60 mL/min/1.73m²
- Proteinuria >300 mg/day
Coding Notes
Document the stage of CKD and its relation to hypertension.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting High Blood Pressure to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I10.
Impact
Clinical: Inaccurate clinical picture., Regulatory: Potential audit issues., Financial: Loss of reimbursement for related conditions.
Mitigation Strategy
Always link hypertension to heart or kidney conditions when present.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Confirm no secondary causes before using I10.
Impact
Failure to document and code complications linked to hypertension.
Mitigation Strategy
Implement thorough documentation practices linking hypertension to all related conditions.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
