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

Primary ICD-10-CM Codes for nitric oxide
Decision Criteria
clinical Criteria
- Echocardiographic evidence of pulmonary hypertension
Applicable To
- Idiopathic pulmonary arterial hypertension
Excludes
- Pulmonary hypertension due to left heart disease (I27.2)
Clinical Validation Requirements
- Echocardiographic evidence of pulmonary hypertension
- Hypoxemia unresponsive to 100% O₂
Code-Specific Risks
- Ensure echocardiographic evidence is documented.
- Avoid use if left heart disease is present.
Coding Notes
- Ensure primary condition is documented before coding for nitric oxide therapy.
P29.3 - Persistent fetal circulation
Use for neonates with persistent fetal circulation treated with inhaled nitric oxide.
Applicable To
- Persistent pulmonary hypertension of the newborn (PPHN)
Excludes
- Congenital heart defects (Q20-Q28)
Clinical Validation Requirements
- Oxygenation index (OI) ≥25
- PaO₂ <60 mmHg on 100% FiO₂
Coding Notes
Document gestational age and response to therapy.
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 Nitric Oxide to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I27.0.
Impact
Clinical: Misrepresentation of patient condition., Regulatory: Non-compliance with coding standards., Financial: Denial of claims and potential audits.
Mitigation Strategy
Use FeNO testing codes only for asthma-related diagnoses.
Impact
Reimbursement: Denial of claims leading to loss of revenue., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of services provided.
Mitigation Strategy
Always append modifier -25 to E&M codes when billing with CPT 95012.
Impact
Lack of documentation for oxygenation index and PaO₂ levels.
Mitigation Strategy
Ensure all clinical criteria are documented before billing.
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.
