Case Study: John Muir Health achieves 99.3% payer revenue yield and 40% denial reduction with Waystar

John Muir Health Drives game changing denial reduction

John Muir Health faced shrinking margins from new payment models and needed a yield‑focused revenue cycle overhaul as part of its REVINATION program. Their patient accounting reporting didn’t match the health system’s goals and internal teams were already stretched, so John Muir evaluated vendors and selected Waystar to augment REVINATION with a denial avoidance strategy across hospitals, the physician network and medical group.

Waystar’s advisory team analyzed historical data, customized reporting, targeted high‑impact denial types, led education and organized denial‑prevention workgroups using solutions including Denial Avoidance (plus Eligibility, Claims Manager and Remit Management). With Waystar’s support John Muir achieved a 99.3% payer revenue yield over three years, cut denials by 40%, earned a top‑quartile Epic Financial Pulse ranking for denial management, and freed two FTEs for professional billing.
