Elevated blood levels of vitamin B12 are generally associated with increased amounts of proteins that carry vitamin B12 in the bloodstream or release of stored vitamin B12. The most obvious cause of an elevated vitamin B12 level is taking too much of the vitamin in the form of supplements.
What does it mean when your blood test shows High B12 Levels?
Vitamin B12 deficiency anemia due to intrinsic factor deficiency

High. An abnormally high vitamin B-12 status is anything over 900 pg/mL. This result may suggest liver or kidney problems, diabetes, or certain forms of leukemia.
There is agreement within the literature that serum vitamin B12 testing should be used to diagnose vitamin B12 deficiency in symptomatic and high-risk populations. One of the leading causes of vitamin B12 deficiency is pernicious anemia, an autoimmune disease that results in the failure to produce intrinsic factor.
Usually, excess vitamin B12 is removed in the urine. Conditions that can increase B12 level include: Liver disease (such as cirrhosis or hepatitis) Myeloproliferative disorders (for example, polycythemia vera and chronic myelogenous leukemia)
The most common cause of high B12 in the blood is due to recent ingestion or injection of supplemental vitamin B12. We don't worry about overdosing on B12 supplements because excess can be excreted in your urine. It could also be possibly from your diet if high in animal products such as meat, eggs, and shellfish.
In some people, high levels of B12 may cause gastrointestinal problems such as bloating and diarrhea. And if you have high blood pressure or poor cardiovascular health, having too much B12 may further complicate these issues. Pregnant and breastfeeding women may also need to be especially mindful of B12 levels.
Vitamin B12 deficiency anemia due to intrinsic factor deficiency. D51. 0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM D51.
Utilization Guidelines Vitamin B-12 (82607) and folate (82746) can be tested up to four times per year for malabsorption syndromes (K90. 9) or deficiency disorders (D81.
A study of elderly Americans in 2007 found that high folate blood levels for patients with normal B12 indicated lower risks of anemia and cognitive impairment. But in patients with low B12, high folate was associated with a higher risk (Morris, 2007).
Abnormally elevated B12 has been attributed many causes [5,6], e.g., myeloid blood malignancies [7,8,9], acute or chronic liver diseases [10,11,12], chronic kidney failure, autoimmune or inflammatory diseases [3], and Gaucher disease [13].
281.1 is a legacy non-billable code used to specify a medical diagnosis of other vitamin b12 deficiency anemia. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
Vitamin B12 deficiency anemia due to malabsorption with proteinuria
Hemolytic anemia caused by chemicals and toxins
Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have.
Code also note - A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
Not getting enough of certain B vitamins can cause diseases. A lack of B12 or B6 can cause anemia.
