January 1, 2026 brings the biggest shift in specialty drug economics in years. Medicare's first-ever negotiated drug prices take effect, including Stelara (66% reduction) and Enbrel (67% reduction).[1] Combined with the new $2,100 Part D out-of-pocket cap[2] and growing biosimilar competition (Stelara biosimilars now offer 80-90% discounts[3]), practices managing infusions and injections face significant changes to acquisition costs, reimbursement, and patient affordability.
Before looking ahead to 2026, it's worth understanding the 2025 landscape. Pharmaceutical manufacturers raised list prices on more than 250 branded drugs in January 2025, according to data from healthcare research firm 3 Axis Advisors reported by Reuters.[4] The median price increase was 4.5%, consistent with recent years and well below the 9% median increases seen a decade ago.[4]
Notable increases that affected specialty practices in 2025:
What this meant for practices: For buy-and-bill drugs, list price increases affect inventory carrying costs and may create a temporary margin gap before ASP-based reimbursement adjusts (typically a 2-quarter lag).[5]
Nine biosimilar versions of Stelara (ustekinumab) have now launched in the U.S. market, with list price discounts ranging from 5% to 90% below the reference product.[3] All approved Stelara biosimilars became interchangeable with the reference product as of April 2025, when Amgen's Wezlana exclusivity period ended.[3] This creates significant opportunities, and complexity, for practices managing IBD, psoriasis, and psoriatic arthritis patients.
What this means for practices: Lower acquisition costs for ustekinumab biosimilars could improve buy-and-bill margins for GI and rheumatology practices. However, formulary placement varies significantly by PBM.[3] Practices should verify biosimilar coverage with each payer and consider the implications for both IV (loading dose) and subcutaneous (maintenance) administration routes.
This is the headline for 2026. The Inflation Reduction Act authorized Medicare to negotiate prices for high-spend drugs, and those negotiated Maximum Fair Prices take effect January 1, 2026.[1] Two of the 10 drugs in this first round—Stelara and Enbrel, are commonly administered via infusion or injection in specialty practices.
CMS estimates that if these negotiated prices had been in effect in 2023, Medicare would have saved $6 billion across all 10 drugs.[1] Medicare beneficiaries using these drugs are projected to save $1.5 billion in out-of-pocket costs when prices take effect in 2026.[1] Learn how these drug pricing changes affect patient out-of-pocket costs and coverage.
What this means for practices in 2026: Stelara is now subject to both biosimilar competition and Medicare negotiated pricing. Practices administering Stelara should evaluate how both factors affect acquisition costs and reimbursement starting January 1. The Medicare $2,100 out-of-pocket cap (up from $2,000 in 2025) may also reduce patient payment barriers for high-cost infusions.[2]
The Inflation Reduction Act requires drug manufacturers to pay rebates to Medicare when drug prices increase faster than inflation. As a result, Medicare beneficiaries pay reduced coinsurance on 64 Part B drugs as of Q1 2025.[8] These are physician-administered drugs, many of which are infused or injected in specialty practices.
For Medicare patients receiving infusions of affected drugs, the coinsurance is calculated on an inflation-adjusted (lower) payment amount rather than the actual ASP.[8] This can result in meaningful out-of-pocket savings for patients and may reduce collection risk for practices.
