| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I10 | Essential (primary) hypertension | Use when hypertension is diagnosed without heart or kidney involvement. |
|
| I11.0 | Hypertensive heart disease with heart failure | Use when hypertension is documented with heart failure. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Decision Criteria
clinical Criteria
- Two separate BP readings >140/90 mmHg
documentation Criteria
- Document absence of heart or kidney disease
Applicable To
- High blood pressure
Clinical Validation Requirements
- Two separate BP readings >140/90 mmHg
- Absence of heart or kidney disease
Code-Specific Risks
- Misclassification with secondary hypertension
Coding Notes
- Ensure two separate elevated readings before coding.
I11.0 - Hypertensive heart disease with heart failure
Use when hypertension is documented with heart failure.
Applicable To
- Hypertension with heart failure
Excludes
- Hypertensive heart and chronic kidney disease (I13.-)
Clinical Validation Requirements
- Documentation of heart failure due to hypertension
Coding Notes
Sequence I11.0 before heart failure codes.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Heart failure
I50.-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 Arterial Hypertension to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I10.
Impact
Clinical: Ambiguous diagnosis, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials
Mitigation Strategy
Specify BP readings, Confirm diagnosis with criteria
Impact
Reimbursement: Incorrect reimbursement for non-chronic condition, Compliance: Non-compliance with ICD-10 guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Use R03.0 for transient or single elevated BP readings.
Impact
Failure to document causality between hypertension and heart/kidney disease
Mitigation Strategy
Ensure clear documentation linking hypertension to comorbid 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.
