Reading the South Dakota tables

South Dakota's 4,109 prescribers wrote 4,942,049 Part D claims in 2024, about $171,515 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.
