| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D70.1 | Chronic congenital neutropenia | Use for patients with confirmed congenital neutropenia, typically diagnosed in childhood. |
|
| D70.8 | Other neutropenia | Use when neutropenia is secondary to drug exposure, confirmed by clinical documentation. |
|
| D70.9 | Unspecified neutropenia | Use when the specific cause of neutropenia is not determined. |
|
| P61.5 | Transient neonatal neutropenia | Use for neonates with transient neutropenia, typically resolving without intervention. |

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

Essential facts and insights about Neutrophil Disorders
Primary ICD-10-CM Codes for neutrophils
Decision Criteria
clinical Criteria
- Genetic confirmation of congenital neutropenia
Applicable To
- Kostmann syndrome
Excludes
- Cyclic neutropenia (D70.4)
Clinical Validation Requirements
- Serial CBCs showing ANC <500 x3 episodes
- Genetic testing confirming congenital origin
Code-Specific Risks
- Misclassification if genetic testing is not confirmed
Coding Notes
- Ensure genetic confirmation to avoid misclassification.
D70.8 - Other neutropenia
Use when neutropenia is secondary to drug exposure, confirmed by clinical documentation.
Applicable To
- Drug-induced neutropenia
Excludes
- Neutropenia due to infection (B95-B97)
Clinical Validation Requirements
- Documentation of drug exposure
- ANC drop ≥50% from baseline
Coding Notes
Ensure drug exposure is clearly documented to support coding.
D70.9 - Unspecified neutropenia
Use when the specific cause of neutropenia is not determined.
Excludes
- Neutropenia due to chemotherapy (D70.8)
Clinical Validation Requirements
- Two CBCs 24h apart showing ANC <1500
Coding Notes
Avoid using D70.9 when more specific codes are applicable.
P61.5 - Transient neonatal neutropenia
Use for neonates with transient neutropenia, typically resolving without intervention.
Clinical Validation Requirements
- Neonatal CBC showing transient ANC drop
Coding Notes
Ensure documentation specifies transient nature.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Neutrophil Disorders to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D70.1.
Impact
Clinical: Inaccurate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential for denied claims
Mitigation Strategy
Always document the specific drug and its temporal relationship to neutropenia.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces data specificity and quality.
Mitigation Strategy
Use specific codes like D70.8 when the cause is known.
Impact
Overuse of D70.9 can trigger audits.
Mitigation Strategy
Use specific codes whenever possible and ensure documentation supports code choice.
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.
