Code Description

ICD-10 D51.3 is a billable code used to indicate a diagnosis of other dietary vitamin b12 deficiency anemia.

Key Diagnostic Point:

Other dietary vitamin B12 deficiency anemia is a type of anemia that occurs due to insufficient dietary intake of vitamin B12, which is essential for the production of red blood cells and proper neurological function. This condition can arise from various dietary habits, particularly in individuals who follow strict vegetarian or vegan diets, as vitamin B12 is primarily found in animal products. Symptoms may include fatigue, weakness, pale skin, and neurological issues such as numbness or tingling in the extremities. Diagnosis typically involves blood tests to measure vitamin B12 levels, complete blood count (CBC), and possibly methylmalonic acid levels. Treatment usually consists of dietary modifications to include vitamin B12-rich foods or supplementation, either orally or via intramuscular injections, depending on the severity of the deficiency. Regular monitoring of vitamin B12 levels is essential to ensure effective management and prevent complications associated with prolonged deficiency.
