Other dietary vitamin B12 deficiency anemia

What This Code Means

Low red blood cell count caused by not getting enough vitamin B12 from diet, such as in strict vegetarian or vegan diets.

Coding Tips

  • •Distinguish this from pernicious anemia (D51.0), which is due to lack of intrinsic factor, not dietary insufficiency
  • •Document dietary history and B12 levels to support this diagnosis
