Are you also charging for the admin fee? At least we can get the pmt for that, plus the god-awful reimbursement for the B12. We are fast getting to the point of having our pts who want B12's for less than medically necessary DX's pay out of pocket. We also will have them purchase the meds thru their pharmacies via RX, and we keep it here for administration (with each pt's name on the vials). We do this with testosterone for the guys and it works great! We're a small practice and can't keep taking the beating on these low allowables, so we get the pts to share. By the way, we have been getting Medicare pmt for B12's on same day as OV, using modifiers and proper ICD-9's. Maybe it's the difference in carriers.
