Most of these Medicare Part D claims are vaccines, 100% of the cost of the top drugs

Most prescribed

Pharmacies often give vaccines under a standing order that names one clinician, and CMS counts every such claim under that clinician's NPI. These claims are therefore not a measure of this clinician's own prescribing.
