I was reviewing the archive and came across a Q&A related to modifier JW. That answer states that the modifier relates only to single-use vials—a vial of liquid medication intended for parenteral administration (injection or infusion) that is meant for use in a single patient for a single case, procedure or injection. This would seem to mean that the modifier would not apply to packages for non-liquid drugs. Is that correct?
The JW modifier applies to single-dose vials, but it also applies to single-use packages for drugs and biologicals that would not be dispensed in liquid form. This is for something such as skin substitutes or other single-use products that are applied or implanted and not infused.
