Dose Rounding to Whole Vials

Rounds an ordered dose to whole vials within a policy threshold.

Open the tool → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.

Example

Dose ordered in
mg/kg
Ordered dose
5
Weight
84 kg
Vial size 1
100 mg
Rounding threshold
10 %

Result: Rounded dose 400 mg (-4.8% from 420 mg): 4 × 100 mg, nothing discarded. As ordered, 420 mg uses 5 × 100 mg, discarding 80 mg (bill the discarded amount with the JW modifier).

The tool opens with these values already filled in. Replace them with your own.

HOPA position statement (Fahrenbruch et al., J Oncol Pract 2018;14(3):e130-e136): rounding biologic and cytotoxic anticancer agents within 10% of the ordered dose is acceptable for routine care; each institution sets its own policy. Read the source ↗
