ICD-10 Code D72.118 – Other hypereosinophilic syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.118 – Other hypereosinophilic syndrome
What it is
Use this code for a hypereosinophilic syndrome that does not fit a more specific ICD-10-CM description. It indicates persistent eosinophilia with organ involvement or risk of damage, as documented by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Common findings include eosinophilia with possible skin, lung, heart, gastrointestinal, or neurologic involvement, but the exact presentation depends on the subtype and affected organ systems.
When to use this code
Assign D72.118 when the provider documents other hypereosinophilic syndrome and does not specify a different eosinophilic disorder. Use it for confirmed cases in which the record supports a hypereosinophilic syndrome diagnosis, even if the involved organ system is also coded separately.
Do not use it for isolated eosinophilia without a syndrome diagnosis. Check documentation if the note only mentions eosinophil elevation, suspected disease, or a different named eosinophilic condition.
Do not use for
Do not use this code for simple eosinophilia, allergic disease, or eosinophilic conditions with a more specific ICD-10-CM code. If the diagnosis is unclear or not confirmed, check documentation.
Coding tip
Code the syndrome only when the provider clearly documents hypereosinophilic syndrome; otherwise, query or code the documented eosinophilia diagnosis.
