ICD-10 Code for Eosinophilia
Also indexed as (allergic) (idiopathic) (secondary)
The ICD-10-CM code for eosinophilia is D72.10 — Eosinophilia, unspecified. This is the code the Alphabetic Index gives for eosinophilia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
D72.10 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which eosinophilia code should you use?
