The spread

1.8× estimated

Medicare paid 1.8× what pharmacies pay.

Part D averages every strength and form sold under “Nabumetone” into one figure, so it is not specific to this NDC.

Cost-plus estimate

$9.42 estimated

$3.84 + $0.58 (15%) + $5.00 fee per fill = $9.42

This is a model, not a price any pharmacy quoted. Shipping is not included. For a pack this cheap, the $5.00 fee is most of the estimate. How it is worked out
