D63.8 ICD-10-CM Code: Anemia in other chronic diseases classified elsewhere

D63.8 is the ICD-10-CM diagnosis code for anemia in other chronic diseases classified elsewhere. Low red blood cell count that develops as a complication of other chronic diseases not specifically listed elsewhere. D63.8 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 aplastic and other anemias and other bone marrow failure syndromes (d60-d64).

D63.8 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.

Code the underlying chronic disease first, then this anemia code as a secondary manifestation.
