Vitamin B12 Absorption Study With Intrinsic Factor Cpt Code
Vitamin B12 is a crucial nutrient for the human body. It plays a vital role in the formation of red blood cells, DNA synthesis, and proper nerve function. However, the human body cannot produce vitamin B12 on its own, and it must be obtained from external sources such as food and dietary supplements.
Once vitamin B12 is consumed, it needs to be absorbed by the body. The absorption process depends on the presence of a protein called intrinsic factor, which is produced by the stomach. Intrinsic factor binds to vitamin B12 and helps it to be absorbed in the small intestine.
The Importance of Vitamin B12 Absorption Study
Some people may have difficulty absorbing vitamin B12 due to a lack of intrinsic factor. This condition is known as pernicious anemia. Additionally, certain medications, such as proton pump inhibitors and metformin, can interfere with vitamin B12 absorption. Therefore, it is essential to measure the level of vitamin B12 in the blood to identify any deficiencies and provide proper treatment.
A vitamin B12 absorption study is a diagnostic test that measures the amount of vitamin B12 absorbed by the body. This test is conducted by injecting a small amount of radioactive vitamin B12 into the patient's bloodstream. The patient's urine is then collected and tested to determine the amount of radioactive vitamin B12 that was absorbed by the body.
The CPT Code for Vitamin B12 Absorption Study with Intrinsic Factor
The Current Procedural Terminology (CPT) code for vitamin B12 absorption study with intrinsic factor is 78290. This code includes the injection of radioactive vitamin B12 and the collection and analysis of the patient's urine over a specified period to determine the amount of vitamin B12 absorbed by the body.
It is important to note that this test is not covered by all insurance plans. Patients should check with their insurance provider to determine if the test is covered and what their out-of-pocket expenses may be.
Conclusion
Vitamin B12 is an essential nutrient that plays a crucial role in the human body. A vitamin B12 absorption study with intrinsic factor can help diagnose any deficiencies and provide proper treatment. The CPT code for this test is 78290, but it is important to check with your insurance provider to determine coverage and costs. Proper diagnosis and treatment of vitamin B12 deficiency can help prevent serious health issues such as pernicious anemia.
