How should providers bill for administered or dispensed dosages with a NDC that was calculated in micrograms (mcg)?
This is a conversion issue that is drug and dosage-specific. Grams (gm) are used for topical forms of medicines as a unit of weight measurement instead of dosage. Micrograms (mcg) are a unit of measurement based on the dosage of the drug. For example: If 400 mcg of a drug was administered with a concentration of 200 mcg per milliliter (mcg/ml) and the HCPCS billing unit was calculated increments of 100 mcg, then providers should bill four HCPCS units (100 mcg x 4 = 400 mcg), but enter the NDC unit of measure as “ML” for two milliliters of the mcg concentration per milliliter (400 mcg ÷ 200 mcg/ml = 2 ml). Providers that may have additional questions about determining NDC quantity for Medi-Cal claims are advised to consult with their pharmacists. • How should providers enter NDC information for drugs that are measured in both grams (gm) and milliliters (ml) at the same time? For example, Albumin 12.5 gm = 240 ml (5% solution). Is there cross-reference in place for units of measurement o
