The spread

5.5× estimated

Medicare paid 5.5× what pharmacies pay.

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

Cost-plus estimate

$5.76 estimated

$0.66 + $0.10 (15%) + $5.00 fee per fill = $5.76

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
