Reading the Missouri tables

Missouri's 26,154 prescribers wrote 39,797,656 Part D claims in 2024, about $229,717 in drug cost per prescriber. A high total usually reflects specialty practice, such as cancer, rheumatology or HIV care, or vaccines: 2 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.
