ICD-10 Code D72.19 – Other eosinophilia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.19 – Other eosinophilia
What it is
D72.19 identifies eosinophilia that does not fit a more specific ICD-10-CM category. Use it when the record documents elevated eosinophils or eosinophilia, but the cause or subtype is not further defined.
Clinical signs
Clinical features vary; refer to documentation. Eosinophilia may be noted on blood testing and can occur with allergic disease, parasitic infection, medication reactions, or other inflammatory conditions.
When to use this code
Use this code when the provider documents “other eosinophilia,” “eosinophilia,” or a similar nonspecific diagnosis without a more precise category. It is also appropriate when the chart confirms eosinophilia but does not identify the underlying cause. Check documentation if a more specific diagnosis is present.
Do not use for
Do not use D72.19 when the record supports a more specific eosinophilic disorder, such as eosinophilic leukemia or organ-specific eosinophilic disease. Also avoid it if eosinophilia is only a lab finding without a documented diagnosis.
Coding tip
Code the documented eosinophilia category only after confirming that no more specific eosinophilic diagnosis applies.
