R00-R99Primary Range
Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
This range includes codes for elevated blood pressure readings without a diagnosis of hypertension, specifically R03.0 for white coat hypertension.
Hypertensive diseases
This range includes codes for essential hypertension (I10) which may be used in conjunction with R03.0 if hypertension is confirmed.

Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R03.0 | Elevated blood pressure reading, without diagnosis of hypertension | Use when there is no prior hypertension diagnosis and ambulatory/home BP confirms normotension. |
|
| I10 | Essential (primary) hypertension | Use when hypertension is confirmed through consistent elevated BP readings in both clinic and home settings. |

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

I10 - Essential (primary) hypertension
Use when hypertension is confirmed through consistent elevated BP readings in both clinic and home settings.
Excludes
- White coat hypertension (R03.0)
Clinical Validation Requirements
- Consistent BP readings ≥130/80 mmHg in both clinic and home settings
Coding Notes
Ensure hypertension diagnosis is supported by consistent BP readings across different settings.

Z79.899Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting White Coat Hypertension to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R03.0.
Impact
Clinical: May lead to misdiagnosis of hypertension., Regulatory: Non-compliance with coding standards., Financial: Potential denial of claims due to insufficient documentation.
Mitigation Strategy
Ensure home BP readings are documented in the patient record., Verify that the diagnosis of white coat hypertension is supported by out-of-office monitoring.
Impact
Reimbursement: Incorrect coding may lead to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data reporting for hypertension prevalence.
Mitigation Strategy
Use I10 and document white coat effect, not diagnosis.
Impact
Coding R03.0 without confirming normotension via ambulatory/home monitoring.
Mitigation Strategy
Require documentation of home BP readings before coding R03.0.
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.
