White Bagging Waste Calculator

1. Enter the white-bagged doses you receive a month, the share that go unused, the average value per dose, and any share credited back.
2. Enter the staff minutes each shipment takes and the loaded hourly cost of whoever handles it.
3. Read the yearly value of unused drug, the handling cost, and the total.

• Doses per year = doses received per month × 12
• Unused doses per year = doses per year × share that go unused
• Value of unused drug = unused doses × average value per dose × (1 − share credited)
• Handling cost = doses per year × staff minutes per shipment ÷ 60 × loaded cost per hour. Each dose is counted as its own shipment, because white-bagged drug comes labeled for one patient.
• Total = value of unused drug + handling cost

With the example values: 60 doses × 12 = 720 doses a year. 8% go unused, so 57.6 doses, about 58. At $4,000 a dose that is $230,400 of drug never given. Handling is 720 × 20 minutes = 240 staff hours, × $45 = $10,800. Total: $241,200. The example values are made up to show the math. They are not a benchmark.

Normally an infusion center buys the drug, stocks it, and bills the payer after the infusion. That is buy-and-bill. With white bagging, the payer requires a specialty pharmacy, often one it picks, to ship the drug to your center for one named patient. The pharmacy bills the payer for the drug, and you bill only for giving it.

The catch: that dose belongs to that patient. If the patient misses the visit, the dose changes, or the order stops, the drug usually cannot be given to anyone else. Follow your pharmacy rules and your state's rules for what can be held, returned, or must be discarded.

A 2024 Avalere survey of 35 provider organizations, funded by the National Infusion Center Association and two other provider groups, estimated unusable white-bagged drug at $35,000 to $652,000 per site per year, plus $13,000 to $67,500 in handling costs. 81% of the practices that white bag said they do it because payer contracts require it.

That is one small survey's range, and the authors caution against applying it broadly. It is not a benchmark for your center. Read the Avalere report (PDF, infusioncenter.org).

• Unused drug usually cannot go to another patient. White-bagged doses are dispensed for one named patient. Whether a dose can be held for that patient's next visit, sent back, or must be destroyed depends on the drug, the pharmacy, and your state's pharmacy rules. Follow them.
• Decide whose money "value" means. The pharmacy usually bills the payer for the drug, so much of the waste lands on the payer and sometimes on the patient as a copay for a dose never given. The handling time is yours either way.
• Count every reason a dose goes unused. No-shows and cancellations are the obvious ones. Dose changes after labs, orders that stop, and shipments that arrive late or expire add up too.
• Time a few real shipments. Receiving, checking against the order, logging, cold storage, and calling about a missing box all count. One honest week of timing beats a guess.

The buy-and-bill margin calculator shows what the same drug earns when you buy it yourself, and the no-show cost calculator covers the chair time a missed visit loses. Drug waste and no-show rate are defined in the infusion center KPI glossary, and the WeInfuse reporting guide covers where orders and visits live.
