The total amount Medicare approved for these services in 2024. It includes what Medicare paid and what patients or their other insurance owed, such as the deductible and coinsurance.

What this does not show: Medicare-allowed amount

30-day fills

1,226 standardized 30-day fills in 2024

$2,484,956 in 2024
