To provide for substantial reductions in the price of prescription drugs for Medicare beneficiaries.

Prescription Drug Fairness Act - Allows any qualified pharmacy to enter into an agreement with the Secretary of Health and Human Services to enable the pharmacy to sell covered outpatient drugs to Medicare beneficiaries (under title XVIII of the Social Security Act) at a reduced price. Requires such an agreement to: (1) entitle the participating pharmacy to purchase any covered outpatient drug listed on the Federal Supply Schedule of the General Services Administration at the participating pharmacy discount price for that drug; and (2) permit the participating pharmacy to purchase under this Act as much of a covered outpatient drug as it sells to Medicare beneficiaries. Sets forth guidelines for determining the participating pharmacy discount price and a special rule for Medicare beneficiaries enrolled in a hospice program. Directs the Secretary to: (1) administer this Act in a manner that uses existing methods of obtaining and distributing drugs to the maximum extent possible, consistent with efficiency and cost effectiveness; and (2) report to the Congress annually regarding the effectiveness of this Act in protecting Medicare beneficiaries from discriminatory pricing by drug manufacturers, along with any appropriate legislative recommendations to further reduce the cost of covered outpatient drugs to such beneficiaries.
