MTSL Group

MTSL Group gives physician practices a better option than handling administrative work in-house or building a full internal team. Based in Portland, Oregon, this medical billing and revenue cycle management outsourcing company covers the back office work that takes time away from patient care. For independent practices and small groups across the United States, MTSL operates as a cost-effective BPO company that handles billing, credentialing, and practice administration without the overhead of hiring full-time staff. The billing and coding service is where most engagements start. MTSL's billers are certified coders who review chart notes and verify CPT, HCPCS, and NDC codes for accuracy before submission. The process includes claim scrubbing, collections, appeals, and follow-up on unpaid claims, with directly related expenses like postage and supplies covered as part of the service. Provider credentialing is another core offering. MTSL manages the entire enrollment and contracting process, submitting applications, making calls to insurers, and following up every 30 days until credentialing is complete. Each step is logged and delivered to the client on a regular tracking spreadsheet. For practices that prefer to manage billing in-house, MTSL also runs customized provider training covering account setup, verification of benefits, claim scrubbing, appeals, and patient collections. MTSL's clients are primarily independent physicians and small specialty practices that need professional administrative support but cannot justify a full internal billing department. The company serves providers in occupational medicine and general practice, and its work extends to bookkeeping and broader business management for clients who want more comprehensive back office support. MTSL was founded in 2011 by a team that had previously run a large medical practice together. When that practice was acquired by a national company, the group put their combined expertise to work for smaller providers. That origin still shapes how the company operates: the focus is on practices underserved by large billing clearinghouses, practices that need a team willing to actually communicate with them. Since 2011, MTSL has expanded its services to physician practices across the United States while keeping the hands-on support that smaller providers depend on. Practices looking to reduce administrative overhead and stabilize billing revenue can contact MTSL Group directly to discuss their situation and explore whether outsourcing their revenue cycle management is the right move.
