What This Code Means
D72.10 is the ICD-10-CM diagnosis code for eosinophilia, unspecified. An elevated number of eosinophils (a type of white blood cell) in the blood without a known cause. D72.10 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).
D72.10 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This is an unspecified eosinophilia code; use only when the cause cannot be determined or documented.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D72.10 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
