I’m not able to find standards for coding if a drug is used for multiple patients in batch processing under the hood.
For instance: Drug X comes in a 500mg single dose vial. HCPCS description says 100mg/unit or 5 units per SDV. Say you batch process two IV’s under the hood with a single entry into an SDV. Common practice in high volume hospital pharmacy IV rooms.
But say the POS is an office setting: Pt. #1 gets 150mg, Pt. #2 gets 250mg. Waste is 100mg. (150+250+100=500mg or 5 units) I can see Pt. #2 could be billed for 4 units.
But does Pt. #1 get billed for 2 units, 1 unit, or 1.5 units? Then does Pt. #2 get billed for 4 units or 3.5 units? If you round the 150mg to 2 units and the 250mg+100mg waste to 4 units, you just billed 6 units for a vial that only contains 5 units.
The 837p SV104 segment allows decimal places. 837P version 5010:Field allows a decimal point in SV104.The field length of eight digits does not include the decimal point. If a decimal is used, the maximum number of digits allowed to the right of the decimal is three. Source:https://www.optum360coding.com/uploa…E%20Sample.pdf
