What Larsen Billing Service does

Larsen Billing Service is a privately held medical billing and revenue cycle management company founded in 2001 by Christine Romney and headquartered in the Salt Lake City, Utah area. The firm operates a fully remote team of 40+ billing, coding, credentialing, auditing, and patient relations professionals, serving hundreds of healthcare practices nationwide across multiple specialty verticals including mental health, OBGYN, pain management, primary care, midwives and birth centers, and urology. Its core technology platform is CollaborateMD, a third-party practice management system which Larsen configures, populates, and manages on behalf of each client, including payer EDI and ERA enrollments.

The company's revenue model is transaction-based, charging commissions typically in the 5%-8% range on client collections as detailed in industry benchmarks it cites. Service offerings span the full revenue cycle from patient registration and insurance verification through coding, claims submission, denial management, payment posting, and accounts receivable follow-up, with adjacent services in credentialing and contracting, compliance and audits, and, more recently, marketing consulting and a midwifery billing training course. Each client receives a dedicated team including billers, coders, account managers, aging specialists, credentialing experts, and patient billing representatives.

Larsen goes to market through a sales-led, relationship-driven motion anchored by educational content (blog, resources), SEO targeting specialty billing keywords, client testimonials, and free consultations. The firm claims national leadership in midwifery and birth center billing with 600+ accounts. It is founder-owned with no institutional investors and operates without geographic restrictions within the United States.
