| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| O13.1 | Gestational hypertension without significant proteinuria, first trimester | Use when gestational hypertension is diagnosed in the first trimester without proteinuria. |
|
| O14.0 | Pre-eclampsia | Use when hypertension is accompanied by proteinuria or end-organ dysfunction. |

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
- BP readings and absence of proteinuria
Applicable To
- Gestational hypertension diagnosed in the first trimester
Excludes
- Pre-eclampsia (O14.-)
Clinical Validation Requirements
- BP ≥140/90 mmHg on two occasions at least 4 hours apart after 20 weeks
- No significant proteinuria
Code-Specific Risks
- Misclassification if proteinuria is present
Coding Notes
- Ensure documentation specifies absence of proteinuria and trimester of diagnosis.
O14.0 - Pre-eclampsia
Use when hypertension is accompanied by proteinuria or end-organ dysfunction.
Applicable To
- Gestational hypertension with proteinuria
Excludes
- Gestational hypertension without proteinuria (O13.-)
Clinical Validation Requirements
- BP ≥140/90 mmHg with proteinuria ≥300 mg/24h
- May include symptoms like headaches, visual changes
Coding Notes
Document proteinuria and any severe features like HELLP syndrome.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Weeks of gestation
Z3A.XXDifferential 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 Pregnancy-Induced Hypertension to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code O13.1.
Impact
Clinical: Impacts clinical decision-making and monitoring., Regulatory: Non-compliance with coding guidelines., Financial: Potential for incorrect DRG assignment.
Mitigation Strategy
Always document gestational age with Z3A.XX codes.
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient care metrics.
Mitigation Strategy
Use O14.X if proteinuria ≥300 mg/24h is documented.
Impact
Using O13 instead of O14 when proteinuria is present.
Mitigation Strategy
Implement regular training sessions on hypertension coding.
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.
