If my critical access hospital enrolls and participates in the 340B Program, will we have to stop participating in our group purchasing organization (GPO)?

No. Under Section 340B(a)(4)(N) of the Public Health Service Act, as amended by the Affordable Care Act, the prohibition against participation in GPO arrangements does not apply to critical access hospitals, rural referral centers, or sole community hospitals. The GPO prohibition only applies to 340B-enrolled disproportionate share hospitals, children's hospitals, and free-standing cancer hospitals.
