What This Code Means
D72.18 is the ICD-10-CM diagnosis code for eosinophilia in diseases classified elsewhere. Elevated eosinophils that occur as a result of another disease or condition the patient has. D72.18 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).
D72.18 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 code requires documentation of the underlying disease causing the eosinophilia; code the primary condition as well.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D72.18 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code requires documentation of the underlying disease causing the eosinophilia; code the primary condition as well.
- •Use this when eosinophilia is secondary to conditions like parasitic infections, allergies, or malignancies.
Code First
- underlying disease, such as:
- chronic myelomonocytic leukemia (C93.1-)
