Reading the Hawaii tables

Hawaii's 5,044 prescribers wrote 4,606,315 Part D claims in 2024, about $200,001 in drug cost per prescriber. A high total usually reflects specialty practice, such as cancer, rheumatology or HIV care. 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.
