## **What is a vitamin B-12 injection?** HCPCS code J3420 refers to an injection of vitamin B-12 (cyanocobalamin), a synthetic form of the vitamin used to treat pernicious anemia, dietary folate deficiency, and other specified B-group deficiencies
If your provider recommends them, Medicare may cover B12 shots for you
When suffering from a Vitamin B12 deficiency, injections are the most effective solution for delivering the nutrient to your body
As an intramuscular (IM) injection, B12/MIC is best administered on either the thigh muscle, or upper arm
For people who dont absorb B12 well, or those whose want to make sure beyond reasonable doubt that theyre getting an ample dose quickly, B12 shots are available via prescription, says Richard Foxx, M.D., a board-certified physician who treats hormonal disorders and nutritional deficiencies
Each mL contains 1,000 mcg cyanocobalamin
