What CSI Pharmacy does

CSI Pharmacy, founded in 2014 by James Sheets, PharmD, IgCP and headquartered in Nash, Texas, is a privately held specialty infusion pharmacy that delivers immunoglobulin (Ig) therapy — both intravenous (IVIg) and subcutaneous (SCIg) — and select specialty biologics to patients with rare and chronic diseases in their homes. The company describes itself as the largest nationwide independent specialty infusion pharmacy; it is licensed in all 50 states, operates eight specialty pharmacy locations across TX, MA, CT, OH, FL, and CA, and maintains a network of 400+ IgNS-certified home infusion nurses serving 4,000+ patients referred by 4,000+ physicians. CSI's core service bundle combines dispensing and home delivery of high-cost specialty drugs with in-home nursing, intake coordination, insurance verification and prior authorization, financial assistance navigation, patient advocacy, and continuous outcomes monitoring through its proprietary Clinical Outcomes 360° Program. The company carries URAC and ACHC accreditations and was the first multi-location specialty pharmacy to receive ACHC Distinction in Ig Therapy (jointly created with the Immunoglobulin National Society) in 2026.

The revenue model is built around recurring specialty pharmacy revenue: CSI bills insurance plans for Ig and biologic infusions as an in-network provider with most major payers, with prior authorization and benefit verification handled in-house. Revenue is supplemented by manufacturer copay programs and nonprofit foundation grants (PAN Foundation, The Assistance Fund, Healthwell, Patient Advocate Foundation, NORD) that reduce patient out-of-pocket costs and support continued therapy adherence. Pricing is not publicly disclosed. GTM is hybrid: enterprise field sales targeting neurologists, immunologists, and specialists via condition-specific enrollment forms; patient/community-led acquisition through disease-specific foundations, the 5,000+ member IVIG & SCIG Facebook support community, and patient conferences; plus content marketing via the company blog. Differentiation rests on IgNS-certified clinical staff, the Clinical Outcomes 360° outcomes program, all-50-state distribution, and reported patient metrics including an NPS of 98 (vs 76 industry average), 98% satisfaction with fill time, and 96% of patients stating they would be very unhappy to switch pharmacies.

Revenue model

1. Specialty Infusion Pharmacy Services: CSI Pharmacy generates revenue through billing insurance plans for specialty infusion medications (Ig therapies and biologics), prior authorizations, and ongoing treatment coordination. The company is in-network with most major insurance providers and handles benefit verification and prior authorization on behalf of patients.
2. Financial Assistance Coordination: CSI helps patients access manufacturer assistance programs, nonprofit foundation grants (PAN Foundation, The Assistance Fund, Healthwell Foundation, Patient Advocate Foundation, NORD), and payment plans. While these services reduce patient burden, they facilitate treatment access and ongoing revenue.

Direct peers

• Option Care Health: Largest U.S. independent provider of home and alternate-site infusion services, offering home Ig therapy, specialty biologics, and home infusion nursing across all 50 states—CSI's most direct national-scale competitor. CSI's CSO Randy Broyles previously held executive roles at predecessor entities (Walgreens-Optioncare).
• KabaFusion: National home infusion company specializing in IVIg, SCIg, and other immunoglobulin therapies for chronic and rare diseases. Operates Ig-certified clinical staff and a similar provider-referral-driven model to CSI, making it a direct competitive peer in home Ig infusion.
• Soleo Health: Privately held specialty infusion provider offering home and alternate-site administration of specialty biologics and Ig therapy. Competes head-to-head with CSI for the same referring physician and patient segments across multiple states.

Broad incumbents

• Accredo (Express Scripts/Evernorth): One of the largest U.S. specialty pharmacies, owned by Cigna's Evernorth/Express Scripts, distributing specialty biologics and Ig products. Represents the vertically integrated PBM-owned model that competes with independents like CSI through captive payer relationships.
• OptumRx (Optum Infusion Pharmacy): Specialty and home infusion pharmacy arm of UnitedHealth Group's Optum, with national scale and direct in-network access through UnitedHealthcare. CSI's CSO Randy Broyles previously held executive roles at Optum Infusion Pharmacy, underscoring the competitive overlap.
• Coram CVS Specialty Infusion Services: CVS Health's home infusion and specialty pharmacy business, providing IVIg and other biologic infusions nationally. A vertically integrated incumbent competing for the same patient population and provider referrals as CSI.

Emerging players

• Vital Care Infusion Services: Franchise-based home infusion network with locations across the U.S. offering specialty biologics, Ig therapy, and home infusion services. A partial-overlap competitor with a more decentralized model than CSI's centrally managed pharmacy locations.
• Nufactor: Specialty home infusion pharmacy focused on immune globulin and other chronic disease therapies. Niche competitor with overlapping clinical focus in Ig therapy and similar referral-based patient acquisition model.
• PromptCare (PromptCare Infusion / InTouch Pharmacy): Specialty home infusion and enteral nutrition company providing Ig therapy and biologics in the home setting. Mid-size competitor with overlapping clinical and operational model in home-based specialty infusion.

Others

• Diplomat Pharmacy (now Optum Specialty Infusion): Formerly one of the largest U.S. independent specialty pharmacies, now part of Optum. Listed here because of direct leadership lineage—CSI's CSO Randy Broyles previously held executive roles at Diplomat Specialty Infusion Group—and shared historical positioning as a large independent specialty pharmacy.
