Why is CMS proposing to cut 340B hospital drug payments again?

CMS wants to reduce 340B Medicare outpatient drug reimbursement from ASP plus 6% to ASP minus 33.4% for 2027, using a hospital acquisition cost survey it says now supports the change. The proposal would shift billions within OPPS, lowering beneficiary drug cost sharing but likely hurting safety-net hospitals while boosting non-drug outpatient payments.
