GPO Prohibition

Definition

The GPO Prohibition is established in the 340B statute and applies to disproportionate share hospitals (DSH), children’s hospitals (PED), and free-standing cancer hospitals (CAN). These entities are prohibited from purchasing covered outpatient drugs through GPOs or GPO-like arrangements as a condition of 340B program participation.

Upon enrollment in the 340B program, an authorizing official from these hospital types must attest to compliance with the GPO Prohibition. This attestation is repeated during annual recertification. Compliance requires that covered outpatient drugs be purchased through 340B accounts, not GPO accounts.

The GPO Prohibition is one of the most common compliance issues for hospital-type covered entities. Violations can occur when purchasing systems are not correctly configured, when new drugs are added to formularies without proper account assignment, or when staff are not adequately trained on the prohibition. HRSA evaluates GPO Prohibition compliance during audits.
