— JANA S., HR MANAGER, GROUP PRACTICE
When I hired Marla to take over our Billing, our Accounts Receivable was a disaster due to a string of previous billers who had done their job incorrectly. As an Executive Director and a nurse, billing is something I need to happen to keep the business running, but that I didn’t understand well, nor did I have time to dig into and I was STRESSED! Marla took the time to sit down and understand the issues that had created the problem, as well as our workflows and goals for the organization. She has turned around our accounts receivable, collecting over $400,000 in claims that had been denied prior to her starting. For a small non profit, this was a game changer! Our days to collect is a fraction of what it was prior to her starting, which has made a tremendous difference in our cash flow. When I have a question or don’t understand something, Marla is extremely responsive and explains things in a way I understand, with a great sense of humor. When I need to make financial presentations- she helps me gather and frame the information correctly. Not only has she turned around our billing process, but helps with Medicare reports that keep us in compliance, and is always willing to assist with other bookkeeping tasks. Our increased rate of collections not only lets me focus on the mission of delivering care at the end of life, but has made it financially possible for me to give raises to my staff to retain the best nurses! If you are looking for a self-directed and competent biller so you can focus on your organization- look no further
— JESSICA S., EXECUTIVE DIRECTOR, HOSPICE OF LARAMIE, LARAMIE, WY
Marla is the most intelligent medical biller I have had the privilege to work with. She currently manages my entire Accounts Receivable and understands the unique intricacies of Durable Medical/Home Infusion billing. No one will work harder to make sure you are paid every penny you deserve!
— JENNA S, PharmD, OWNER QUALITY IV CARE, LARAMIE, WY
Working with Marla has always been an extremely positive experience. She is very professional and an excellent communicator. I would absolutely recommend her for billing and coding services. She will certainly go above and beyond for your business.
— KIM W., MD OBGYN
I've had the pleasure of knowing Marla for almost 10 years. She is very knowledgeable in the area of medical billing, both outpatient and inpatient. Beyond that she works very well with providers, staff, peers and patients.
— AMY S., PRACTICE MANAGER, MULTI-SPECIALTY PRACTICE
More and more health care providers have ceased offering to help us patients manage our health insurance. It’s a hugely complex service that costs a lot to a business that we need to be focused on providing quality care, not dealing with how it’s paid for. This trend pushes the insurance relationship upon us patients. We need to submit our own claim forms, which require such things as diagnosis codes and treatment codes, the main language of the health insurance industry. Without Marla’s help, I would be hopelessly lost in this process. Marla is easy to reach, responds quickly and is incredibly patient with my endless questions. She clearly knows the insurance industry inside and out so she gets me the answers I need very quickly and without needing any back and forth to understand her replies. As the insurance-avoidance trend among the caregiving community increases and my wife and I are aging (anyone else?), we will be reaching out to Marla at 307 Billing more and more for help submitting our claim forms.
— DAVID P., PATIENT, LOVELAND, CO
Despite the complexity of my billing requirements, Marla and her team managed everything seamlessly. I was consistently impressed by the prompt and clear communication from Marla. A truly positive and efficient billing team, I wholeheartedly recommend them to anyone in need of top-notch billing services.
