About coding simple chronic anemia
The ICD-10-CM code for simple chronic anemia is D53.9 (Nutritional anemia, unspecified).
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.
Don't confuse with (Excludes1 for D53.9)
- anemia NOS (D64.9)
