Harvard Pilgrim has developed a new medical policy for Vitamin B12 screening and testing. Effective for dates of service beginning October 1, 2016, Harvard Pilgrim does not consider routine vitamin B12 screening and testing in healthy, asymptomatic adults medically necessary and will not offer reimbursement for this testing in these cases.
Harvard Pilgrim will offer coverage of medically necessary vitamin B12 screening and testing for members who are clinically symptomatic or considered high-risk for deficiency due to certain medical conditions. For a complete list of the conditions in which vitamin B12 screening and testing is considered medically necessary, please refer to the Vitamin B12 Screening and Testing Medical Policy.
In addition, Harvard Pilgrim considers the testing of methylmalonic acid (MMA) medically necessary for the diagnosis of vitamin B12 deficiency when vitamin B12 levels are borderline-low or low.
However, the testing of holo-transcobalamin as a marker of vitamin B12 is considered investigational/experimental.
