Our Story

Physicians’ Management Solutions, Inc first opened its doors in Bullhead City, AZ in 2002. Committed to being the most respected Medical Billing Service in the tri-state area, PMSI quickly gained a reputation for excellence and expanding its services to Southern California where its corporate office is now located. 

With super friendly and knowledgeable staff, we offer full service medical billing and consulting services for all your medical practice needs. While we specialize in cardiology, neurology, pain management and internal medicine, our clients are diverse and range from large specialty groups to small individual practices.

We view our relationships with our clients as partnerships, our clients’ success is our success. We assign a personalized Account Manager and Claims Specialist to each of our clients and use highly efficient and accurate processes leaving little room for errors. This means minimized rejection rates and maximized reimbursements.

Medical Billing

Our comprehensive billing services include electronic claims submission and remittance with thorough claims follow up and aging analysis; an extensive balancing system that ensures the accuracy of all payments and charge posting; regular patient statement generation; and courteous billers who are always available for patient inquiries.

Eligibility, Verification, Authorizations & Referrals

To help your front office and to ensure a consistent and maximized revenue cycle, we offer insurance eligibility verification as well as authorization and referral services.

Practice Consulting and Credentialing

Enjoy all the benefits of partnering with PMSI including handling your billing and managing other areas of your practice. We offer expert credentialing and contract negotiations in addition to general practice consulting.

Why Choose PMSI?

Accurate and thorough billing

We take your collections seriously and work to ensure that all payments are made by both insurance carriers and patients within an acceptable time frame.

Extensive check-and-balance method

We keep impeccable records to ensure that no charges or payments are lost or unaccounted for.

Timely and efficient system

Aging is done regularly and claims which are not paid are followed up in a timely manner. Secondary claims are sent out within one day of payment of the primary claims. Patient statements are sent out regularly.


We make every effort to ensure that no claim goes out without an appropriate, payable diagnosis, and if there is a denial, we investigate and get every possible payment. Nothing is neglected or “shoved under the rug” as is often the case with in-house or “too-busy” billers.

Great customer service

We’re always friendly and courteous, and available during working hours to patients who have questions regarding their accounts.

Tech-savvy and up-to-date systems

We process most claims electronically to ensures faster reimbursement. We use a web-based dropbox, as well as web-based scanning and storage.

Experienced and qualified staff

Our staff are experienced in both electronic and paper claims, and are well versed in a large variety of medical software. We have experts in coding, billing, accounting, collections, aging, workers-comp, contracts, and credentialing.

Individual attention backed by a team-approach

We assign an Account Manager and Claims Specialist to each client for personalized and specific attention, but also take a team approach for information gathering, problem solving, and the sharing of expertise. Thus, our physicians are assured the attention and skill of not just one person, but a whole group of professionals with a wide range of knowledge and experience.

Minimized rejection rates

Medical necessity and scrubbing checks substantially minimize rejection rates.

All transactions 100% HIPAA compliant and securely encrypted

With the rising success of her company, Cynthia became certified in Corporate Healthcare Compliance at George Washington University, and EMR Implementation by GE Healthcare.
