AMBSI

AMBSI is a medical billing and revenue cycle management company based in Manhattan, serving healthcare providers across New York City and the Tri-State area. With more than 1,200 billing and coding experts and over 1,500 satisfied customers, AMBSI functions as a specialized outsourcing partner for practices and facilities that want to improve reimbursement performance without adding internal administrative overhead. The company's services cover every stage of the revenue cycle. Eligibility verification, claim preparation and submission, payment posting, denial follow-up, accounts receivable recovery, prior authorization support, medical credentialing, and provider enrollment are all part of the offering. AMBSI's dedicated AR service analyzes aging receivables to identify unpaid claims, rejected claims, underpayments, and stalled appeals that quietly limit what a practice collects. Performance reporting gives providers visibility into where revenue is being lost and what is being done about it. AMBSI's client base includes independent practices, multispecialty medical groups, ambulatory surgery centers, pain management specialists, anesthesia providers, and hospitals. The team currently serves providers across more than 75 specialties. Because billing rules and payer requirements vary significantly by specialty, AMBSI structures its workflows around each organization's specific payer mix, staffing setup, and practice-management systems rather than applying a one-size process. Operating from its Manhattan office at 276 5th Avenue, Suite 704, AMBSI supports healthcare organizations throughout Manhattan, Brooklyn, Queens, the Bronx, Long Island, Westchester County, and Rockland County. The team works with multiple EHR platforms, so providers do not need to replace their existing systems to get started. HIPAA-compliant data handling and structured denial-prevention workflows are built into every engagement, with the goal of catching billing errors before submission rather than chasing them after the fact. For healthcare providers considering back-office outsourcing to a US-based BPO company, AMBSI offers a direct path to more consistent billing performance. Rated 5.0 by healthcare providers, the team is available at (800) 996-0076 or info@ambsi.com to discuss specific practice needs, review AR challenges, or outline a revenue cycle management engagement.
