ICD-10-CM Code D51.0
Vitamin B12 deficiency anemia due to intrinsic factor deficiency

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

D51.0 is a billable ICD code used to specify a diagnosis of vitamin B12 deficiency anemia due to intrinsic factor deficiency. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code D510 is used to code Pernicious anemia

Pernicious anemia (also known as vitamin B12 deficiency anemia, Biermer's anemia, Addison's anemia, or Addison–Biermer anemia) is one of many types of the larger family of megaloblastic anemias. One way pernicious anemia can develop is by loss of gastric parietal cells, which are responsible, in part, for the secretion of intrinsic factor, a protein essential for subsequent absorption of vitamin B12 in the ileum.
