The Rheumatology Reimbursement Landscape
The clinic bills for care. The economics run on the drug.
In rheumatology, infused biologics dominate the top line — so the practice lives or dies on a buy-and-bill margin that is thin, spread-based, and under active attack.
Infliximab and other IV agents make the medication the largest revenue line by a wide margin, but the money is a spread, not a fee. Medicare pays these Part B drugs at ASP+6% (before sequestration), while commercial plans price off AWP or WAC — so the same vial earns very different margin depending on the payer, the contract, and the acquisition cost you actually paid. E/M visits, infusion administration codes, laboratory panels, and DEXA scans round out the P&L, but none of them approaches the scale of the drug.
At the same time, payers are moving aggressively to pull that drug line out of the office. White- and brown-bagging mandates and specialty-pharmacy carve-outs threaten to strip in-office infusion margin entirely; biosimilar substitution resets the spread on every new ASP cycle; and medical-versus-pharmacy-benefit steerage decides whether the practice touches the drug at all. Layer on step therapy, prior authorization, and the rapid PE consolidation of rheumatology and infusion platforms, and the same infusion suite can be worth dramatically different amounts depending on how it is contracted and defended — which is precisely where Fulcrum works.
