What This Code Means
D72.110 is the ICD-10-CM diagnosis code for idiopathic hypereosinophilic syndrome [ihes]. A rare disorder characterized by persistently elevated eosinophils in the blood that causes organ damage, with no identifiable secondary cause. D72.110 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering other disorders of blood and blood-forming organs (d70-d77).
D72.110 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28, V24, ESRD, or RxHCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
IHES is a diagnosis of exclusion; ensure secondary causes of hypereosinophilia have been ruled out before coding this.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D72.110 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •IHES is a diagnosis of exclusion; ensure secondary causes of hypereosinophilia have been ruled out before coding this.
