Most of these Medicare Part D claims are vaccines, 100% of the cost of the top drugs
24 Medicare Part D claims for 24 beneficiaries, against an average of 794 among the 463 providers of this specialty who prescribed in Part D. Brand-name drugs were 96% of claims.
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.
