Eliminates the requirement that hospitals enrolled in the 340B program report the National Drug Code numbers for drugs administered by a physician if the state is precluded from seeking a rebate on such drugs because they were purchased at a discount under the 340B program.

Removes the exclusion that prohibited covered entities added to the 340B program under the Patient Protection and Affordable Care Act from purchasing drugs for a rare disease or condition as covered outpatient drugs.

Treats a facility or organization that is eligible for the 340B program as satisfying any geographic location requirements in relation to a hospital or a critical access hospital for purposes of determining provider-based status under Medicare.
