CodeDescriptionWhen to UseKey Documentation
D72.110Idiopathic hypereosinophilic syndromeUse when no underlying cause is identified for the eosinophilia and organ damage is present.
  • Eosinophil count ≥1.5 x10^9/L on two occasions at least four weeks apart
  • Exclusion of secondary causes such as parasitic infections or autoimmune diseases
D72.111Lymphocytic variant hypereosinophilic syndromeUse when clonal T-cells are identified as the cause of eosinophilia.
  • Flow cytometry showing clonal T-cells
  • Elevated serum IL-5 or TARC levels

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

  • Confirmed idiopathic nature after excluding secondary causes

Applicable To

  • Idiopathic HES

Excludes

  • Drug-induced eosinophilia (D72.12)

Clinical Validation Requirements

  • Eosinophil count ≥1.5 x10^9/L on two occasions at least four weeks apart
  • Exclusion of secondary causes such as parasitic infections or autoimmune diseases

Code-Specific Risks

  • Misclassification if secondary causes are not thoroughly excluded

Coding Notes

  • Ensure thorough documentation of exclusion of secondary causes.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Heart failure, unspecified

I50.9
Use to document cardiac involvement in HES.

Other specified respiratory disorders

J98.89
Use to document pulmonary involvement in HES.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Lymphocytic variant hypereosinophilic syndrome

D72.111
Presence of clonal T-cells and elevated IL-5 levels.

Idiopathic hypereosinophilic syndrome

D72.110
Absence of clonal T-cells.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Hypereosinophilic Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D72.110.

Impact

Clinical: Misdiagnosis of HES type., Regulatory: Non-compliance with coding standards., Financial: Potential denial of claims.

Mitigation Strategy

Thoroughly document all tests conducted to exclude secondary causes., Use templates to ensure comprehensive documentation.

Impact

Reimbursement: May lead to reduced reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases the accuracy of health data.

Mitigation Strategy

Always specify the subtype of HES based on clinical findings.

Impact

Risk of audits due to use of unspecified codes.

Mitigation Strategy

Ensure detailed documentation and use of specific codes.

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.

Specialty: Cardiology

Required Elements

  • Subjective symptoms
  • Objective lab results
  • Assessment and diagnosis
  • Plan including treatment and follow-up

Example Documentation

Patient admitted with NYHA Class III heart failure secondary to idiopathic HES.

Poor Documentation Example
Patient admitted with eosinophilia.
Good Documentation Example
Admitted with heart failure secondary to idiopathic HES (AEC 2.1 x10^9/L).
Explanation
The good example specifies the type of HES and associated conditions.
