- WBC >50 x10³/μL
- Toxic granulation
- No splenomegaly
- Recent infection or trauma
Code-Specific Risks
- Confusing with chronic neutrophilic leukemia
Coding Notes
- Ensure documentation specifies the reactive nature of the leukocytosis.
D72.819 - Elevated white blood cell count, unspecified
Use when the cause of elevated WBC is unspecified.
Excludes
- Leukemoid reaction (D72.823)
Clinical Validation Requirements
- WBC 11-25 x10³/μL
- No documented cause
- Transient elevation
Coding Notes
Avoid using when specific causes are documented.
D47.1 - Chronic neutrophilic leukemia
Use for chronic neutrophilic leukemia confirmed by molecular testing.
Applicable To
- Chronic neutrophilic leukemia with CSF3R mutation
Excludes
- Reactive neutrophilia (D72.823)
Clinical Validation Requirements
- WBC >25 x10³/μL persistent >3 months
- Splenomegaly
- CSF3R mutation
Coding Notes
Ensure molecular testing is documented.

T45.1X5ADocumentation & Coding Risks
Avoid these common documentation and coding issues when documenting Neutrophilic Leukocytosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D72.823.
Impact
Clinical: May lead to inappropriate treatment., Regulatory: Non-compliance with coding guidelines., Financial: Potential for claim denials.
Mitigation Strategy
Thorough clinical documentation., Regular coding audits.
Impact
Reimbursement: May affect DRG assignment and reimbursement., Compliance: Non-compliance with coding specificity requirements., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Use D72.823 for leukemoid reaction if reactive causes are documented.
Impact
Using unspecified codes when specific codes are applicable.
Mitigation Strategy
Regular training on coding specificity.
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.
