About coding nutritional deficiency anemia
The ICD-10-CM code for nutritional deficiency anemia is D53.9 (Nutritional anemia, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D53.9.
Within D53, choose D53.9 (Nutritional anemia, unspecified) only when documentation doesn't support a more specific option: protein deficiency anemia (D53.0), other megaloblastic anemias, not elsewhere classified (D53.1), Scorbutic anemia (D53.2) and other specified nutritional anemias (D53.8).
Don't report D53.9 together with the conditions in its Excludes1 note: anemia NOS (D64.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
