ANEX Anesthesia Group

What ANEX Anesthesia Group does

ANEX Anesthesia Group (legal entity ANEX, S.C.) is a physician-owned anesthesiology practice headquartered in Waukesha, Wisconsin, and the largest Wisconsin-based, physician-owned anesthesiology practice in southeastern Wisconsin. Founded in 1994, the group fields 32 or more board-certified or board-eligible MD anesthesiologists (no CRNAs) with combined experience exceeding 500 years, including subspecialty coverage in cardiothoracic, pediatric, pain medicine, and regional anesthesiology. The group delivers general anesthesia, monitored anesthesia care, and regional anesthesia techniques on-site at ProHealth Care's Waukesha Memorial Hospital, Oconomowoc Memorial Hospital, and ProHealth Care Moreland Surgery Center, and is the exclusive anesthesia provider at Bluemound Surgery Center.

The practice's differentiated clinical offering is the Enhanced Recovery After Surgery (ERAS) protocol co-developed with Orthopedic Associates of Wisconsin and ProHealth Care for total knee replacement patients, combined with ultrasound-guided Adductor Canal Nerve Blocks and continuous catheter infusion via the On-Q pump system for up to 72 hours of outpatient post-operative pain control. Documented outcomes include 1-2 day discharge timelines and reduced opioid consumption relative to conventional pathways. The underlying "technology" is procedural know-how and protocolized multi-modal analgesia rather than software or platform infrastructure.

ANEX generates revenue through professional service agreements with healthcare facilities; pricing is not publicly disclosed and billing inquiries are routed to Fusion Anesthesia Solutions, LTD. The go-to-market is exclusively enterprise field sales into hospital systems and ASCs, with no direct-to-patient acquisition motion. Patient acquisition flows entirely through facility referrals at ProHealth Care locations and Bluemound Surgery Center, making the practice's commercial footprint identical to its facility partner footprint in Waukesha County.
