| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D72.10 | Eosinophilia, unspecified | Use when eosinophilia is detected but no specific cause is identified. |
|
| D72.19 | Other eosinophilia | Use when eosinophilia is secondary to a known cause such as a drug reaction. |
|
| K20.0 | Eosinophilic esophagitis | Use when biopsy confirms eosinophilic esophagitis. |

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 elevated eosinophils
Decision Criteria
clinical Criteria
- Eosinophil count between 500-1,499/μL without organ damage.
Applicable To
- Initial workup of eosinophilia
- Transient elevation without identified cause
Excludes
- Hypereosinophilic syndrome (HES)
- Eosinophilic esophagitis
Clinical Validation Requirements
- CBC showing eosinophils 500-1,499/μL
- No organ involvement
Code-Specific Risks
- Risk of undercoding if specific cause is identified later.
Coding Notes
- Ensure no specific cause is documented before using this code.
D72.19 - Other eosinophilia
Use when eosinophilia is secondary to a known cause such as a drug reaction.
Applicable To
- Drug-induced eosinophilia
- Allergic eosinophilia
Excludes
- Eosinophilic esophagitis
- Hypereosinophilic syndrome
Clinical Validation Requirements
- Documentation of drug reaction or allergy
- IgE elevation
Coding Notes
Ensure the cause of eosinophilia is documented.
K20.0 - Eosinophilic esophagitis
Use when biopsy confirms eosinophilic esophagitis.
Applicable To
- Eosinophilic esophagitis confirmed by biopsy
Excludes
- Gastroesophageal reflux disease (GERD)
Clinical Validation Requirements
- Biopsy showing ≥15 eosinophils/HPF
- Exclusion of GERD
Coding Notes
Ensure biopsy results and exclusion of GERD are documented.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Elevated Eosinophils to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D72.10.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Thorough patient history, Detailed clinical notes
Impact
Reimbursement: May result in lower reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Use D72.19 or other specific codes when the cause is known.
Impact
Risk of audits due to use of unspecified codes when specific causes are documented.
Mitigation Strategy
Ensure documentation clearly supports the chosen code.
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.
