Built specifically for CMS TEAM model launching January 2026 — mandatory episodic payment reform for 5 major surgical procedures. Up to $100M revenue impact per health system. ## Company Overview Rainfall Health is an AI platform built specifically for the CMS Transforming Episode Accountability Model (TEAM), which took effect January 1, 2026 — mandatory episodic payment reform requiring participating hospitals to manage the total cost and quality of care for 90 days following five major surgical procedures: lower extremity joint replacement, surgical hip fracture, spinal fusion, coronary artery bypass graft, and major bowel procedures. The company raised $15 million in Series A financing in February 2026. TEAM creates both risk and opportunity: hospitals that manage episode costs below benchmarks earn bonuses of up to 20% of the episode payment, potentially representing $100+ million in annual revenue for a large health system. Hospitals that exceed benchmarks face penalties. Rainfall's AI platform helps health systems identify which patients are at risk for high-cost post-acute care, coordinate discharge planning, and track episode performance in real time. The regulatory lock-in effect for early adopters is significant: TEAM participation creates a 5-year commitment to episode-based payment, and hospitals that deploy Rainfall's analytics in the first year develop institutional workflow dependencies that make switching costly. This creates a defensible moat for Rainfall among the 750+ hospitals participating in TEAM. ## Frequently Asked Questions ### What does Rainfall Health do?
