California Medical Billing

About California Medical Billing

California Medical Billing & Revenue Management (CMB) was founded in 2003 by Jennifer Tullius with a focused mission: ensuring California physicians receive the reimbursements they've earned. Headquartered in Rancho Cucamonga, CA, CMB operates as a 100% US-based billing and revenue cycle management firm exclusively serving medical practices across California. The company offers a proprietary 5-Point Revenue System designed to improve claim acceptance rates, with a reported 98% collections rate in 2024 and over $34 million in revenue collected for client practices. CMB's service portfolio spans three RCM365 tiers—Precision RCM (billing and collections), End-To-End Revenue Optimization (staffing, billing, and collections), and Comprehensive RCM Partnership (billing, credentialing, and consulting)—as well as standalone credentialing support, new practice consulting, and RCM consulting. The team specializes in navigating California-specific insurance environments, including CA HMO, CA Medicare, and CA Medi-Cal regulations, providing physicians with full transparency through detailed billing reports and account access. CMB positions itself as a revenue advocacy partner rather than a simple data-entry service.
