Emerald Health LLC (Medical Billing Services)

Independent medical practices lose real revenue when billing partners fail to keep up. Emerald Health was founded in 2010 specifically to solve that problem. Dr. Arun Rajan, a board-certified neurologist, built the company after cycling through billing vendors who overpromised and underdelivered, including at his own practice. Rather than accept the status quo, he developed a billing model from the ground up. Sixteen years later, that model has collected more than $200 million for clients and holds a denial rate consistently under 3%, making Emerald Health a proven medical billing BPO company serving independent practices across the USA. The core service is medical billing built for the specialties where coding complexity is highest and billing errors cost the most. Emerald's team handles claim scrubbing and submission, denial rework and resubmission, payment posting and reconciliation, and specialty-specific coding expertise. Beyond billing, the company provides end-to-end revenue cycle management, covering eligibility verification, prior authorization, accounts receivable recovery, aging follow-up, and reporting dashboards that give practice owners full visibility into every dollar. For practices dealing with administrative staffing gaps, Emerald also provides HIPAA-compliant virtual staff who integrate directly into existing workflows, a back-office outsourcing solution designed to function as an extension of the practice rather than a separate vendor relationship. Emerald Health works exclusively with independent and ambulatory practices, particularly in specialties where the margin for revenue cycle error is lowest. The company currently serves more than 20 practices nationwide, with hands-on experience across neurology, family medicine, and other specialties that demand precise, coding-aware billing. Operations span three locations: Massachusetts, Texas, and Chennai, India. This footprint supports broad coverage and responsive turnaround across multiple time zones. Day-to-day revenue cycle work is led by Senthil Vel, Director of Revenue Cycle, who brings more than 18 years of medical billing expertise to the role, including a decade running Emerald's own operations team. Technology infrastructure and HIPAA compliance are overseen by co-founder Sathesh Parameswaran, whose enterprise systems background shapes the company's security protocols and operational continuity. Practices looking to reduce denial rates, recover aging accounts receivable, or fill administrative staffing gaps can schedule an introductory conversation through the Emerald Health website. There are no setup fees and no hidden costs.
