Reading the Louisiana tables

Louisiana's 20,790 prescribers wrote 30,157,903 Part D claims in 2024, about $231,901 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.
