Experience You Can Trust
Over 28 years of medical billing expertise dedicated to supporting hospitals, physicians, and patients.
Hello, my name is Stefanie McArn, Certified Professional Biller, (CPB). I am a medical biller for both hospital and professional billing. I have over 23 years of dialysis billing experience and spent the past 5 years billing a variety of inpatient and outpatient hospital services. Altogether I have over 28 years of billing experience, my love of this profession has grown exponentially.
My experiences throughout my career birthed a compassion in me for physicians, patients, and families. My integrity and tenacity for physicians and hospitals to be 100 percent reimbursed for the amazing services they provide in the great state of Michigan, has kept me fully engaged and invested with understanding the need for accuracy in the ever growing and evolving field of medical billing.

"Stefanie assisted with my struggling billing department. She initiated training of new staff and offered continued support with weekly follow up calls ensuring that the team continued on the correct track. She also assisted in collecting over $1,000,000 in outstanding claims that dated 2-3 years. She is a gem!!!"​
