PMSi

What PMSi does

PMSi (Physicians' Management Solutions, Inc.) is a privately held, founder-owned medical billing and physician practice management company headquartered in Torrance, California, with additional offices in Las Vegas, Nevada and Bullhead City, Arizona. Founded in 2002 by Cynthia (Sadiya) Mirza after she established a community clinic in Southern Nevada in 1999, the company delivers outsourced revenue cycle management, eligibility verification and authorizations, credentialing, contract negotiation, and general practice consulting to medical practices of all sizes — from individual practitioners to large specialty groups — across the Southwestern United States, with particular specialization in cardiology, neurology, pain management, internal medicine, and pulmonology.

The company's service model is people-led rather than software-led: each client is assigned a dedicated Account Manager and Claims Specialist, supported by a team with expertise across coding, billing, accounting, collections, aging, workers' compensation, contracts, and credentialing. The underlying technology stack is conventional rather than proprietary — a web-based platform supporting electronic claims submission, remittance processing, scrubbing checks, and a web-based document dropbox and storage system — integrated with multiple third-party EMR and billing systems including GE Centricity Practice Solutions (now Athena Practice Solutions), AthenaOne, Practice Fusion, and RXNT. The CEO also previously served as a consultant to one of GE Healthcare's largest VARs to train staff and implement Centricity EMR.

PMSI generates revenue primarily through monthly subscription-style billing engagements whose pricing varies by the size and needs of each practice, supplemented by professional-services revenue from credentialing, contract negotiations, and consulting. Distribution is direct: enterprise field sales targeting larger specialty groups, combined with an inside-sales motion through phone (1-800-693-9020), email, website contact forms, and regional SEO landing pages for Los Angeles, Las Vegas, and Torrance. The company claims 100% HIPAA-compliant encryption across all transactions and emphasizes a personalized, team-approach service model as its core differentiator.
