ICD-10 Code D72.111 – Lymphocytic Variant Hypereosinophilic Syndrome [LHES] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.111 – Lymphocytic Variant Hypereosinophilic Syndrome [LHES]
What it is
D72.111 identifies lymphocytic variant hypereosinophilic syndrome, a form of hypereosinophilic syndrome driven by abnormal lymphocyte activity. It is used when eosinophilia is linked to this specific variant.
Clinical signs
Clinical features vary; refer to documentation. Typical findings in hypereosinophilic syndromes may include persistent eosinophilia and organ involvement, but you should code only when the lymphocytic variant is clearly documented.
When to use this code
Use D72.111 when the provider documents lymphocytic variant hypereosinophilic syndrome or LHES. Apply it for confirmed diagnoses, including encounters focused on evaluation, monitoring, or management of this specific subtype. If the record only says eosinophilia or hypereosinophilic syndrome without the variant, check documentation.
Do not use for
Do not use this code for nonspecific eosinophilia, allergic conditions, or hypereosinophilic syndrome without documented lymphocytic variant. If the subtype is not stated, do not assume LHES.
Coding tip
Code the documented subtype exactly; if LHES is not explicitly named, query the provider.
