Reading the Delaware tables

Delaware's 4,475 prescribers wrote 5,223,073 Part D claims in 2024, about $213,165 in drug cost per prescriber. A high total usually reflects specialty practice, such as cancer, rheumatology or HIV care, or vaccines: 1 of the 50 largest totals are mostly vaccines, which pharmacies often bill under a standing order naming one clinician. These are billing tables, not quality ratings. PlainDoctor does not rank named prescribers by opioid share; the state's opioid figures above come from CMS's own totals.
