At the August 2015 WG2 meeting the form was discussed.
Requested: Clarification of the BUS:
Request: Definity (Perflutren Lipid Spheres) injectable suspension is an ultrasound contrast agent. Definity is supplied as a single use 2ml clear glass vial containing clear liquid in packages of 4 and 16. Before administration, Definity must be activated by shaking the vial for 45 minutes using a Vialmix apparatus. The PI does not indicate how much volume is yielded after activation of Definity. Labeling indicates that the product is supplied in 2ml vials. The outer package shows a 1.5ml volume before activation. The SPL portion of DailyMed shows that the product comes in 1.5ml vhttp://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=8ab9c79c-1b5c-4e86-899c-cc74686f070a#S11.
Why Needed: Looking for compendia to agree on primary package size: 1.5 or 2ml?

Outcome Anticipated: Per BUS section 5.2.2: Injectables that are liquid filled vials, must be billed as the total number of ML dispensed. If a manufacturer has labeled a product for the quantity to dispense (i.e. excluding theoverfill), the reported quantity for dispensing should be total number of milliliters. FAQ 7.28 indicates that Lucentis PS was based on the dispensed volume and not the total volume (with overfill). However, in the case of Definity it is not clear what the activated volume is.
Discussion: Via email discussion prior to the TG call:
I would like to confirm the BU=ml and PS=8 for 11994001104 DEFINITY 1.1 MG/ML VIAL
And BU=ml and PS=32 for 11994-0011-16 DEFINITY 1.1 MG/ML VIAL
http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=8ab9c79c-1b5c-4e86-899c-cc74686f070a
Some compendia had as 1.5ml and some as 2ml. One had listed as 1.5 based on what DailyMed has on Ingredients and Appearance section under packaging.

However the prescribing information does not mention the 1.5 mL

Discussion by Product Review and BU Exceptions TG call of July 28, 2015:
This came from a customer inquiry. It is not a widely used pharmacy product—more of a diagnostic agent. Since 2 mL is predominately shown and not the 1.5 mL, a motion was made and seconded that this is a BU=mL with a vial quantity of 2 mLs per section 5.2.2 of the BUS. The motion carried. The task group recommends a new FAQ be added to the BUS to clarify.
NDC (11994-011-01), vial (2mL x 1 = 2 mL)
NDC (11994-011-04), 4 vial kit (2mL x 4 = 8 mL)
NDC (11994-011-16), 16 vial kit (2mL x 16 = 32mL)
(Note to the Application of the BU TG: This decision was primarily based on what was predominately displayed on the label. The pharmacist would see 2mL and not 1.5 mL.)
At this meeting, a motion was made and seconded to classify the BU=mL with a vial quantity of 2 mL per Section 5.2.2 of the BUS.
NDC (11994-011-01), vial (2mL x 1 = 2 mL)
NDC (11994-011-04), 4 vial kit (2mL x 4 = 8 mL)
NDC (11994-011-16), 16 vial kit (2mL x 16 = 32mL)
The motion carried without opposition.
