What This Code Means
D52.0 is the ICD-10-CM diagnosis code for dietary folate deficiency anemia. A type of anemia caused by not getting enough folate (a B vitamin) from food, resulting in insufficient red blood cells. D52.0 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 nutritional anemias (d50-d53).
D52.0 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.
Document the dietary cause clearly to distinguish from drug-induced or other causes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D52.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the dietary cause clearly to distinguish from drug-induced or other causes
- •Consider coding any underlying nutritional deficiency or dietary condition that contributed to the folate deficiency
