On July 15, 2025, the Centers for Medicare & Medicaid Services (CMS) released the CY 2026 Outpatient Prospective Payment System (OPPS) proposed rule. The proposed rule includes a provision that would increase the reduction in OPPS payment rates to offset the lump sum payments previously paid to 340B hospitals from 0.5% to 2% and would accelerate the period of the reductions from 16 years to six years. This payment reduction would apply to most items and services and most hospitals paid under OPPS. The reduction is not limited to 340B hospitals. CMS also proposes to reduce payments under OPPS for drug administration at most off-campus hospital outpatient departments not already subject to site-neutral payments to the rate paid under the Medicare Physician Fee Schedule (PFS), representing an approximately 65% reduction in payments.
CMS is accepting comments on this proposal through September 13, 2025.
The proposed rule was published in the Federal Register on July 17, 2025 and is available here.
