D51.9

Billable

Vitamin B12 deficiency anemia, unspecified

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A condition where the body doesn't have enough vitamin B12, leading to a shortage of healthy red blood cells. The specific cause is not documented or identified.

Coding Tips

  • Query the provider if the cause is known (pernicious anemia, dietary deficiency, malabsorption) as more specific codes exist
  • Verify if this is due to medications, dietary restrictions, or gastrointestinal conditions that should be coded separately
