What state do you live in? I know in Texas we use Trailblazer Medicare and they require we put the hgb(hemoglobin) or hct(hematocrit) level on the claim in order to pay for it as of April 1, 2008.Can anyone tell me how to get Medicare to pay for a B12. I use 90772 for administration and J3420 for drug and they get denied. Medicare rep says there is a way to get paid, but won't tell me how. Any suggestions?
