Our Story

So, how did we become an industry leader in medical billing and consulting in the US? Before you outsource billing and collections to us, here is our story.

Missing Piece began in the early 2000s when Deana Sewell, CEO and founder, helped a friend whose child was diagnosed with autism. Deana was able to get her friend’s medical insurance policy to change their original decision and cover the critical ABA therapy services their child needed.

Realizing that there were many families facing this situation who didn’t know the intricacies of how to bill insurance for ABA therapy, Deana left her executive position at a bank to establish Missing Piece Billing & Consulting Solutions in Kokomo, Indiana. Deana and expert medical billing consultants at Missing Piece pioneered the process for ABA billing and helped lay the groundwork for insurance coverage so those needing ABA therapy services could access them. Soon, the company released innovative ABA therapy practice management software and expanded to include additional services like occupational therapy billing.

Over the years, Missing Piece has grown significantly, serving ABA providers across the U.S. and expanding their billing services to a variety of behavioral health providers. While the Missing Piece team has grown, the mission and values that Deana founded the company on have remained the same. That is to be the best outsourced medical billing consultant company that works with care and compassion. The top benefit of outsourcing ABA billing to Missing Piece is that it allows practices to give their patients more of their time and the quality care that they deserve.

What Clients Say..

Like most small businesses, our success is predicated upon personal relationships and a consistent revenue stream.  Since opening, Missing Piece Billing has been a great partner and an essential element of both.  They guided us through the billing and authorization process and took the lead on contracting and patient invoicing, allowing us to focus on serving our families.  As our company has grown from 1 to 100, I can say with great confidence that we would not be where we are today without them.

Missing Piece delivers. Your problems are solved before you even notice, and you benefit from knowledge gained by Missing Piece via other clients’ problems even before they are yours to suffer. They are ahead of the game at every turn, be it denials for improperly reviewed claims, contracting issues, or auth utilization, they have you covered. We could not replace their services with ten full time staffers, and they cost far less than that each month.

Partnering with Missing Piece to handle our insurance and billing needs came at the perfect time for our organization.  Payment and issues with claims consumed a large portion of our week.  Once we started working with the team at Missing Piece, we experienced faster turnaround with payment, billing and authorizations were streamlined, and credentialing couldn’t be easier.  Their dedicated team is always there to support our business and has given us back the time to focus on patient care.

When we began the process to become a Medicaid and insurance provider, a friend advised us to call Missing Piece for help.  As it turns out, that was the best piece of advice we got in relation to this journey.  The folks at Missing Piece have been there every step of the way, providing us with guidance, support, and taking many hours of work onto their workload.  We are so grateful!
