Reading the Maine tables

Maine's 7,378 prescribers wrote 8,010,923 Part D claims in 2024, about $195,777 in drug cost per prescriber. A high total usually reflects specialty practice, such as cancer, rheumatology or HIV care, or vaccines: 3 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.
